ipnodes(4)ipnodes(4)NAMEipnodes - The IP node name database
SYNOPSIS
/etc/ipnodes
DESCRIPTION
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 canoni‐
cal_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 nota‐
tion using the inet_pton() routine from the Internet address manipula‐
tion library. Node names may contain any printable character other
than a field delimiter, newline, or comment character.
