The hostid program just calls the gethostid() function from the C library.

Comment 2 Jakub Jelinek 2004-12-10 12:46:31 UTC

If /etc/hostid doesn't exist (where you can set hostid to anything you want),
gethostid returns IP address of your hostname.
So it depends on how have you configured your networking.
7f0100 means your hostname's IP address is on lo interface, just don't do that.
