I'm not too worried about someone r00ting my 10.1.1.x name servers - but 
the point's well taken... ;)

Curses.  I can control resolv.conf, but I didn't think that the DHCP 
server was required to give out the name servers in any particular 
order.  So, I don't know for sure that all of the machines are getting 
the same main server.  They probably are, and my situation is far from 
"overloading" the name servers, but it just strikes me as kinda crummy 
to not take advantage of local data when possible.

Eh, I'm off to find a bind discussion list.

Thanks.
