file contains information regarding
the known hosts on the DARPA Internet.
For each host a single line should be present
with the following information:
.HP 10
official host name
.br
.ns

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.
.PP
Network addresses are specified in the conventional
``.'' notation using the \fIinet_addr\fP() routine
from the Internet address manipulation library,
.IR inet (3N).
Host names may contain any printable
character other than a field delimiter, newline,
or comment character.
