NAME

6       ParseUtil::Domain - Domain parser and puny encoder/decoder.
7

SYNOPSIS

9         use ParseUtil::Domain ':parse';
10
11           my $processed = parse_domain("somedomain.com");
12           #$processed:
13           #{
14               #domain => 'somedomain',
15               #domain_ace => 'somedomain',
16               #zone => 'com',
17               #zone_ace => 'com'
18           #}

DESCRIPTION

21       This purpose of this module is to parse a domain name into its
22       respective name and tld. Note that the tld may actually refer to a
23       second- or third-level domain, e.g. co.uk or plc.co.im.  It also
24       provides respective puny encoded and decoded versions of the parsed
25       domain.
26
27       This module uses TLD data from the Public Suffix List
28       <http://publicsuffix.org/list/> which is included with this
29       distribution.

140        Everyone is permitted to copy and distribute verbatim copies
141        of this license document, but changing it is not allowed.
142
143                                   Preamble
144
145         The license agreements of most software companies try to keep users
146       at the mercy of those companies.  By contrast, our General Public
147       License is intended to guarantee your freedom to share and change free
148       software--to make sure the software is free for all its users.  The
149       General Public License applies to the Free Software Foundation's
150       software and to any other program whose authors commit to using it.
151       You can use it for your programs, too.
152
153         When we speak of free software, we are referring to freedom, not
154       price.  Specifically, the General Public License is designed to make
155       sure that you have the freedom to give away or sell copies of free
156       software, that you receive source code or can get it if you want it,
157       that you can change the software or use pieces of it in new free
158       programs; and that you know you can do these things.
159
160         To protect your rights, we need to make restrictions that forbid
161       anyone to deny you these rights or to ask you to surrender the rights.
162       These restrictions translate to certain responsibilities for you if you
163       distribute copies of the software, or if you modify it.
164
165         For example, if you distribute copies of a such a program, whether
166       gratis or for a fee, you must give the recipients all the rights that
167       you have.  You must make sure that they, too, receive or can get the
168       source code.  And you must tell them their rights.
169
170         We protect your rights with two steps: (1) copyright the software, and
171       (2) offer you this license which gives you legal permission to copy,
172       distribute and/or modify the software.
173
174         Also, for each author's protection and ours, we want to make certain
175       that everyone understands that there is no warranty for this free
176       software.  If the software is modified by someone else and passed on, we
177       want its recipients to know that what they have is not the original, so
178       that any problems introduced by others will not reflect on the original
179       authors' reputations.
180
181         The precise terms and conditions for copying, distribution and
182       modification follow.
183
184                           GNU GENERAL PUBLIC LICENSE
185          TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
186
187         0. This License Agreement applies to any program or other work which
188       contains a notice placed by the copyright holder saying it may be
189       distributed under the terms of this General Public License.  The
190       "Program", below, refers to any such program or work, and a "work based
191       on the Program" means either the Program or any work containing the
192       Program or a portion of it, either verbatim or with modifications.  Each
193       licensee is addressed as "you".
194
195         1. You may copy and distribute verbatim copies of the Program's source
196       code as you receive it, in any medium, provided that you conspicuously and
197       appropriately publish on each copy an appropriate copyright notice and
198       disclaimer of warranty; keep intact all the notices that refer to this
199       General Public License and to the absence of any warranty; and give any
200       other recipients of the Program a copy of this General Public License
201       along with the Program.  You may charge a fee for the physical act of
202       transferring a copy.
203
204         2. You may modify your copy or copies of the Program or any portion of
205       it, and copy and distribute such modifications under the terms of Paragraph
206       1 above, provided that you also do the following:
207
208           a) cause the modified files to carry prominent notices stating that
209           you changed the files and the date of any change; and
210
211           b) cause the whole of any work that you distribute or publish, that
212           in whole or in part contains the Program or any part thereof, either
213           with or without modifications, to be licensed at no charge to all
214           third parties under the terms of this General Public License (except
215           that you may choose to grant warranty protection to some or all
216           third parties, at your option).
217
218           c) If the modified program normally reads commands interactively when
219           run, you must cause it, when started running for such interactive use
220           in the simplest and most usual way, to print or display an
221           announcement including an appropriate copyright notice and a notice
222           that there is no warranty (or else, saying that you provide a
223           warranty) and that users may redistribute the program under these
224           conditions, and telling the user how to view a copy of this General
225           Public License.
226
227           d) You may charge a fee for the physical act of transferring a
228           copy, and you may at your option offer warranty protection in
229           exchange for a fee.
230
231       Mere aggregation of another independent work with the Program (or its
232       derivative) on a volume of a storage or distribution medium does not
233       bring the other work under the scope of these terms.
234
235         3. You may copy and distribute the Program (or a portion or derivative of
236       it, under Paragraph 2) in object code or executable form under the terms of
237       Paragraphs 1 and 2 above provided that you also do one of the following:
238
239           a) accompany it with the complete corresponding machine-readable
240           source code, which must be distributed under the terms of
241           Paragraphs 1 and 2 above; or,
242
243           b) accompany it with a written offer, valid for at least three
244           years, to give any third party free (except for a nominal charge
245           for the cost of distribution) a complete machine-readable copy of the
246           corresponding source code, to be distributed under the terms of
247           Paragraphs 1 and 2 above; or,
248
249           c) accompany it with the information you received as to where the
250           corresponding source code may be obtained.  (This alternative is
251           allowed only for noncommercial distribution and only if you
252           received the program in object code or executable form alone.)
253
254       Source code for a work means the preferred form of the work for making
255       modifications to it.  For an executable file, complete source code
256       means all the source code for all modules it contains; but, as a
257       special exception, it need not include source code for modules which
258       are standard libraries that accompany the operating system on which the
259       executable file runs, or for standard header files or definitions files
260       that accompany that operating system.
261
262         4. You may not copy, modify, sublicense, distribute or transfer the
263       Program except as expressly provided under this General Public License.
264       Any attempt otherwise to copy, modify, sublicense, distribute or transfer
265       the Program is void, and will automatically terminate your rights to use
266       the Program under this License.  However, parties who have received
267       copies, or rights to use copies, from you under this General Public
268       License will not have their licenses terminated so long as such parties
269       remain in full compliance.
270
271         5. By copying, distributing or modifying the Program (or any work based
272       on the Program) you indicate your acceptance of this license to do so,
273       and all its terms and conditions.
274
275         6. Each time you redistribute the Program (or any work based on the
276       Program), the recipient automatically receives a license from the original
277       licensor to copy, distribute or modify the Program subject to these
278       terms and conditions.  You may not impose any further restrictions on the
279       recipients' exercise of the rights granted herein.
280
281         7. The Free Software Foundation may publish revised and/or new versions
282       of the General Public License from time to time.  Such new versions will
283       be similar in spirit to the present version, but may differ in detail to
284       address new problems or concerns.
285
286       Each version is given a distinguishing version number.  If the Program
287       specifies a version number of the license which applies to it and "any
288       later version", you have the option of following the terms and
289       conditions either of that version or of any later version published by
290       the Free Software Foundation.  If the Program does not specify a
291       version number of the license, you may choose any version ever
292       published by the Free Software Foundation.
293
294         8. If you wish to incorporate parts of the Program into other free
295       programs whose distribution conditions are different, write to the author
296       to ask for permission.  For software which is copyrighted by the Free
297       Software Foundation, write to the Free Software Foundation; we sometimes
298       make exceptions for this.  Our decision will be guided by the two goals
299       of preserving the free status of all derivatives of our free software and
300       of promoting the sharing and reuse of software generally.
301
302                                   NO WARRANTY
303
304         9. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
305       FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
306       OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
307       PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
308       OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
309       MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
310       TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
311       PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
312       REPAIR OR CORRECTION.
313
314         10. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
315       WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
316       REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
317       INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
318       OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
319       TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
320       YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
321       PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
322       POSSIBILITY OF SUCH DAMAGES.
323
324                            END OF TERMS AND CONDITIONS
325
326               Appendix: How to Apply These Terms to Your New Programs
327
328         If you develop a new program, and you want it to be of the greatest
329       possible use to humanity, the best way to achieve this is to make it
330       free software which everyone can redistribute and change under these
331       terms.
332
333         To do so, attach the following notices to the program.  It is safest to
334       attach them to the start of each source file to most effectively convey
335       the exclusion of warranty; and each file should have at least the
336       "copyright" line and a pointer to where the full notice is found.
337
338           <one line to give the program's name and a brief idea of what it does.>
339           Copyright (C) 19yy  <name of author>
340
341           This program is free software; you can redistribute it and/or modify
342           it under the terms of the GNU General Public License as published by
343           the Free Software Foundation; either version 1, or (at your option)
344           any later version.
345
346           This program is distributed in the hope that it will be useful,
347           but WITHOUT ANY WARRANTY; without even the implied warranty of
348           MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
349           GNU General Public License for more details.
350
351           You should have received a copy of the GNU General Public License
352           along with this program; if not, write to the Free Software
353           Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston MA  02110-1301 USA
354
355       Also add information on how to contact you by electronic and paper
356       mail.
357
358       If the program is interactive, make it output a short notice like this
359       when it starts in an interactive mode:
360
361           Gnomovision version 69, Copyright (C) 19xx name of author
362           Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
363           This is free software, and you are welcome to redistribute it
364           under certain conditions; type `show c' for details.
365
366       The hypothetical commands `show w' and `show c' should show the
367       appropriate parts of the General Public License.  Of course, the
368       commands you use may be called something other than `show w' and `show
369       c'; they could even be mouse-clicks or menu items--whatever suits your
370       program.
371
372       You should also get your employer (if you work as a programmer) or your
373       school, if any, to sign a "copyright disclaimer" for the program, if
374       necessary.  Here a sample; alter the names:
375
376         Yoyodyne, Inc., hereby disclaims all copyright interest in the

395       Preamble
396
397       The intent of this document is to state the conditions under which a
398       Package may be copied, such that the Copyright Holder maintains some
399       semblance of artistic control over the development of the package,
400       while giving the users of the package the right to use and distribute
401       the Package in a more-or-less customary fashion, plus the right to make
402       reasonable modifications.
403
404       Definitions:
405
406         - "Package" refers to the collection of files distributed by the Copyright
407           Holder, and derivatives of that collection of files created through
408           textual modification.
409         - "Standard Version" refers to such a Package if it has not been modified,
410           or has been modified in accordance with the wishes of the Copyright
411           Holder.
412         - "Copyright Holder" is whoever is named in the copyright or copyrights for
413           the package.
414         - "You" is you, if you're thinking about copying or distributing this Package.
415         - "Reasonable copying fee" is whatever you can justify on the basis of media
416           cost, duplication charges, time of people involved, and so on. (You will
417           not be required to justify it to the Copyright Holder, but only to the
418           computing community at large as a market that must bear the fee.)
419         - "Freely Available" means that no fee is charged for the item itself, though
420           there may be fees involved in handling the item. It also means that
421           recipients of the item may redistribute it under the same conditions they
422           received it.
423
424       1. You may make and give away verbatim copies of the source form of the
425       Standard Version of this Package without restriction, provided that you
426       duplicate all of the original copyright notices and associated
427       disclaimers.
428
429       2. You may apply bug fixes, portability fixes and other modifications
430       derived from the Public Domain or from the Copyright Holder. A Package
431       modified in such a way shall still be considered the Standard Version.
432
433       3. You may otherwise modify your copy of this Package in any way,
434       provided that you insert a prominent notice in each changed file
435       stating how and when you changed that file, and provided that you do at
436       least ONE of the following:
437
438         a) place your modifications in the Public Domain or otherwise make them
439            Freely Available, such as by posting said modifications to Usenet or an
440            equivalent medium, or placing the modifications on a major archive site
441            such as ftp.uu.net, or by allowing the Copyright Holder to include your
442            modifications in the Standard Version of the Package.
443
444         b) use the modified Package only within your corporation or organization.
445
446         c) rename any non-standard executables so the names do not conflict with
447            standard executables, which must also be provided, and provide a separate
448            manual page for each non-standard executable that clearly documents how it
449            differs from the Standard Version.
450
451         d) make other distribution arrangements with the Copyright Holder.
452
453       4. You may distribute the programs of this Package in object code or
454       executable form, provided that you do at least ONE of the following:
455
456         a) distribute a Standard Version of the executables and library files,
457            together with instructions (in the manual page or equivalent) on where to
458            get the Standard Version.
459
460         b) accompany the distribution with the machine-readable source of the Package
461            with your modifications.
462
463         c) accompany any non-standard executables with their corresponding Standard
464            Version executables, giving the non-standard executables non-standard
465            names, and clearly documenting the differences in manual pages (or
466            equivalent), together with instructions on where to get the Standard
467            Version.
468
469         d) make other distribution arrangements with the Copyright Holder.
470
471       5. You may charge a reasonable copying fee for any distribution of this
472       Package.  You may charge any fee you choose for support of this
473       Package. You may not charge a fee for this Package itself. However, you
474       may distribute this Package in aggregate with other (possibly
475       commercial) programs as part of a larger (possibly commercial) software
476       distribution provided that you do not advertise this Package as a
477       product of your own.
478
479       6. The scripts and library files supplied as input to or produced as
480       output from the programs of this Package do not automatically fall
481       under the copyright of this Package, but belong to whomever generated
482       them, and may be sold commercially, and may be aggregated with this
483       Package.
484
485       7. C or perl subroutines supplied by you and linked into this Package
486       shall not be considered part of this Package.
487
488       8. The name of the Copyright Holder may not be used to endorse or
489       promote products derived from this software without specific prior
490       written permission.
491
492       9. THIS PACKAGE IS PROVIDED "AS IS" AND WITHOUT ANY EXPRESS OR IMPLIED
493       WARRANTIES, INCLUDING, WITHOUT LIMITATION, THE IMPLIED WARRANTIES OF
494       MERCHANTIBILITY AND FITNESS FOR A PARTICULAR PURPOSE.
