Overload some records for intern use

[Johan VAN RYSEGHEM]

Hello all,

my problem is quite simple, but I've tried a lot of different setups, 
none worked :(

My company's DNS are hosted by an third-operator. In the zone 
"websiteburo.com", there are several A records, pointing on our 
different servers.
My problem is: a few of these servers are hosted locally in our offices, 
so i'd like to setup a DNS server which would:
1/ return local addresses for a subset of records
2/ forward the queries to the external server if it cannot answer

Of course i could probably write a batch which retrieves the zone from 
the external server and rewrites some records with local addresses, but 
I think there could be a more elegant way to do this.

Help would be welcome

Thanx in advance
