ipnodes - The IP node name database
The ipnodes file contains information regarding the known
IP nodes (both IPv4 and IPv6) on the network. For each
node a single line should be present with the following
information: IP_address canonical_nodename aliases
Items are separated by any number of blanks or tab characters,
or both. The # (number sign) indicates the beginning
of a comment; characters up to the end of the line
are not interpreted by routines which search the file.
Network addresses, both IPv4 and IPv6, are specified in
the IPv6 notation using the inet_pton() routine from the
Internet address manipulation library. Node names may
contain any printable character other than a field delimiter,
newline, or comment character.
Functions: getaddrinfo(3), getnameinfo(3), inet_pton(3)
