If you are giving out DHCP addresses, you are almost certainly giving
out DNS server addresses, and you can point that to one or more that
you control (probably on the same box(es) as the dhcp service).  And
that DNS server can answer for your local registered or private domain
names as well as the rest of the world.   And it will work by actually
following network standards instead of relying on ancient proprietary
broadcast schemes.
