And if not, hardcode em. It's not like your usual nameserver will be 
behind a nat anyway, and generally, a DNS server is a DNS server.*


* Yes, there are times when your DNS server might be serving active 
directory DNS that's not otherwise publicly viewable, but it'll still be 
using globally available addressing, and you can restrict queries by IP 
address and range, allowing global use of the same nameserver, while 
only exposing the AD stuff to your internal network.
