What I'd like to do is this... right now my NIC answers 212.12.12.212
(for instance) externally and that's the address I use for Apache's
NameVirtualHost directives. I would also like my NIC to answer on
252.12.12.212 (second network connection) and serve the same VirtualHost
directives...

So, what happens is, in NS1.NAMESERVER.NET (which is on the 212 network)
the A record for my box is 212.12.12.212 and, if that network should
fail, the requests will be answered by NS2.NAMESERVER.NET (which is on
the 252 network) and it has an A record for my box of 252.12.12.212. So,
in effect, the name server's availability actually directs the traffic
to the available network connection.

Does that make sense?
