i've never seen someone hide their master internally (where dhcp runs),
only externally (to keep it from getting hacked or ddos'd).  yymv.

would it make sense to add syntax to dhcpd.conf allowing you to select
the address to which updates will be sent, thus bypassing res_findzonecut()?
(this is the logical equivilent of specifying the server when running the
nsupdate shell-level command.)
