   interface on the machine, you can create a [[http://man.openbsd.org/man5/hostname.if.5][=hostname.if(5)=]] file
   with the name =/etc/hostname.<if>=, where =<if>= is the name of the

-  possible to write out the full subnet mask after our IP, separated

   Now we run [[https://man.openbsd.org/man8/netstart.8][=netstart(8)=]] to reconfigure the interface according to the
   file we've just edited.
