We have 2 DNS on BIND9 working as 1 Primary and 1 Secondary, serving our customers in network A. network A is peered with network C without any congestion.
There is another ISP, say network B owner; B and C is peered but very much congested inbetween.
A and B is not directly peered.
So If A>C, no congestion If A>B, need to go thru upstream or thru C (very congested)
Domain ABC.tld has 2 different IPs for network B and C, and is hosted in both network.
The problem network A have at the moment, is the query from the roots from network A will return network B's IP of ABC.tld instead of network C's, resulting our customer's route to the domain requires longer time or time out.
Question: Is it possible for us to set up a forwarder for that specific .tld? we would like to forward the related tld to the DNS in network C.
