16 Represents constants used in DHCP protocol, defined in RFC 1533, RFC
17 2132, RFC 2241, RFC 2485, RFC 2563, RFC 2937, RFC 3004, RFC 3011, RFC
18 3046.

21 As mentioned above, constants can either be imported individually or in
22 sets grouped by tag names. The tag names are:
23 · bootp_codes
25 Imports all of the basic BOOTP constants.
27 (01) BOOTREQUEST
29 (02) BOOTREPLY
30 · htype_codes
32 Imports all HTYPE (hardware address type) codes.
34 (01) HTYPE_ETHER
36 (06) HTYPE_IEEE802
37 (08) HTYPE_FDDI
38 Most common value is HTYPE_ETHER for "Ethernet".
40 · dhcp_message
42 Import all DHCP Message codes.
44 (rfc2132)
46 (01) DHCPDISCOVER
48 (02) DHCPOFFER
49 (03) DHCPREQUEST
50 (04) DHCPDECLINE
51 (05) DHCPACK
52 (06) DHCPNAK
53 (07) DHCPRELEASE
54 (08) DHCPINFORM
55 (09) DHCPFORCERENEW
56 (rfc4388)
58 (10) DHCPLEASEQUERY
60 (11) DHCPLEASEUNASSIGNED
61 (12) DHCPLEASEUNKNOWN
62 (13) DHCPLEASEACTIVE
63 Nb. Previously Cisco used 13 for DHCPLEASEQUERY. If you need to
65 decode or encode packets to communicate with such a system, you
66 might simply use the integer rather than the constant - or use the
67 updated constant and comment in your code appropriately.
68 · dho_codes
70 Import all DHCP option codes.
