I've seen this done two ways... one, using the "class c trick" as it was
called by the tech who did it for me involved setting up records like this
in my forward zone:
12.34.56.78 IN CNAME mydomain.com.
then, apparently, their nameservers queried my forward zones, and added
them to their nameservers. that seemed pretty kludgy to me, but i'm told
it's in relatively widespread use (by lazy people).
the other way i saw it done was with a bsd socks firewall that had a dns
proxy set up, which worked a lot better but seemed far more involved.
