The file associates Internet (IP) addresses with official network names
and aliases. This allows the user to refer to a network by a symbolic

A line cannot start with a blank (tab or space character). Items are
separated by any number or combination of blanks. A character indi‐
cates the beginning of a comment. Characters from the up to the end of
the line are not interpreted by routines which search the file. Trail‐
ing blanks are allowed at the end of a line. For the Internet, this
file is normally created from the official network database 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 networks.
Network numbers can be specified in conventional Internet dot notation
using the routine from the internet address manipulation library (see
inet(3N). Network names can contain any printable character other than
a white space, new-line, or comment character.
