[1mNAME
     [0mhostid - display identifier of current host system

[1mSYNOPSIS
     hostid

DESCRIPTION
     [0mThe _h_o_s_t_i_d command prints the identifier of the current host
     in hexadecimal.  This numeric value is expected to be unique
     across all hosts and is derived from the host's Ethernet
     network hardware address.	If the host has no network inter-
     face hardware, the value will be reported as 0: in this case
     alternative action should be taken to determine a unique
     identifier for the host.

[1mSEE ALSO
     [0mgethostid(2)

[1mNOTES
     [0mThe identifier is presently reported as a 32-bit number:
     this is not guaranteed to be unique since Ethernet network
     hardware addresses are unique only as 48-bit quantities.
