It can't, unless you give your machines fixed IPs. e.g., in
your /etc/dhcpd.conf, put something like:

host erdos {
  hardware ethernet 00:80:AD:76:35:7D;
  fixed-address erdos.home;
}

host pythagoras {
  hardware ethernet 00:C1:28:00:EE:E9;
  fixed-address pythagoras.home;
}

and so on for all the other machines you have.  You can also use DHCP to
set
up DNS and default gateways and such for the other machines:

option routers euclid.home;
option netbios-name-servers euclid.home;
option domain-name-servers euclid.home;
option domain-name "home";

Possible.  Bind is a real pain to set up, though. I'm not even sure it's
possible if you have dynamically assigned IPs.
