na_hosts - host name data base
/etc/hosts
The hosts file contains information regarding the known
hosts on the network. For each host an entry should be
present with the following information:
Internet-address official-host-name aliases
When both IPv4 and IPv6 addresses are configured for a
particular host, there will be a separate entry in the
file for each address. Items are separated by any number
of blanks and/or tab characters. A ``#'' indicates the
beginning of a comment; characters up to the end of the
line are not interpreted by routines which search the
file. The maximum line length is 1022 characters. There
is no way to continue an entry past the end of the line.
This file may be created from the official host data base
maintained at the Network Information Control Center
(NIC), though local changes may be required to bring it up
to date regarding unofficial aliases and/or unknown hosts.
IPv4 network addresses are specified in the conventional
``.'' (dot) notation. IPv6 addresses are specified in any
of the conventional forms i.e., the colon delimited compressed
form or the mixed IPv6 and IPv4 notation. Host
names may contain any alphanumeric character, but not
field delimiters, newline, or comment characters.
