the customary way of doing this would be to use say your Gentoo box to
run both a full DNS and DHCP server (the ISC versions) and to configure
DHCP to update DNS when it hands out an IP address.
The trick is not to just masquerade (or forward) all DNS requests but
rather create your own local domain (and reverse domain for finding
names from ip addresses) and have the DNS server handle those
authoritatively and merely serve as a caching server for everywhere
else.
