may be required to bring it up to date regarding unofficial aliases and/or
unknown hosts. As the data base maintained at is incomplete, use of the
name server is recommended for sites on the Internet. Network addresses
are specified in the conventional ‘‘.’’ (dot) notation using the routine from
the Internet address manipulation library, Host names may contain any
printable character other than a field delimiter, newline, or comment character.
