hostid(1C)                      TCP/IP 5.4.2                      hostid(1C)


NAME
       hostid - set or print identifier of host system

SYNOPSIS
       hostid [ identifier ]

DESCRIPTION
       The hostid command (without an argument) prints the identifier of the
       current host in hexadecimal.  This numeric value is expected to be
       unique across all hosts and is normally set to the host's Internet
       address.  The superuser can set the hostid by specifying identifier
       as an argument.  The parameter required at boot time is defined in

           /etc/tcpip.params

and is used in

    /usr/sbin/init.d/rc.tcpipport.

EXAMPLE
       To specify a host with Internet address 128.211.10.4:

       hostid 80d30a04

SEE ALSO
       hostname(1C), gethostid(2), sethostid(2), hostname(5).

NOTE
       Most programs look up the host name in the hostname database, rather
       than use hostid.
