>But, which DNS server is dhcpd going to try to update?
If you specified a zone declaration in the dhcpd.conf file then it
will use the specified server. If not then it will use the correct
"correct server" is the authoritative server listed in the zones SOA
record - so if your dns is correctly set up then it will all happen
automagically. Of course, if you have bogus data in your dns then the
dhcp server will attempt to update the wrong place.

All this is, of course, as "as seen by the dhcp server" which will
consult the servers specified in your resolv.conf file to find the
SOA record for the zone being updated.
