NAME

6       "getaddrinfo" - command-line tool to "getaddrinfo(3)" resolver
7

SYNOPSIS

9       getaddrinfo [options...] host service
10

DESCRIPTION

12       This tool provides a convenient command-line wrapper around the
13       getaddrinfo(3) resolver function. It will perform a single lookup and
14       print the returned results in a human-readable form. This is mainly
15       useful when debugging address resolution problems, because it allows
16       inspection of the getaddrinfo(3) behaviour itself, outside of any real
17       program that is trying to use it.
18

OPTIONS

20       --host, -H HOST
21               Hostname to resolve. If not supplied, will use the first
22               positional argument
23
24       --service, -S SERVICE
25               Service name or port number to resolve. If not supplied, will
26               use the second positional argument.
27
28       -4      Restrict to just "AF_INET" (IPv4) results
29
30       -6      Restrict to just "AF_INET6" (IPv6) results
31
32       --stream
33               Restrict to just "SOCK_STREAM" results
34
35       --dgram Restrict to just "SOCK_DGRAM" results
36
37       --proto PROTO
38               Restrict to just results of the given IP protocol
39
40       --passive
41               Set the "AI_PASSIVE" hint; results will used to bind() and
42               listen() rather than connect()
43
44       --canonical
45               Retrive the canonical name for the requested host
46
47       --help  Display a help summary and exit
48

OUTPUT FORMAT

50       Each line of output will be given in a form that indicates the four
51       result fields of "ai_family", "ai_socktype", "ai_protocol" and
52       "ai_addr". The first three are printed in the form of a socket(2) call,
53       either symbolically or numerically, and the latter is printed as a
54       plain string following it. For example
55
56        socket(AF_INET , SOCK_STREAM, IPPROTO_TCP) + '127.0.0.1:80'
