Hi I have a question from my boss that I would like a better answer for than what I told him. We have 4 DNS servers across our main Datacenter and one Disaster recovery site. We have forwarders configured on each server for several DNS servers on the Internet.
The question was asked if there was a reason we do it that way instead of having all DNS requests forwarded to one DNS server and then have only that one configured with forwarders for outside the network. I told him it was mainly for redundancy and if everything was going to one server and that one goes down so would the Internet.
Are there other reasons this should not be done or maybe I am all wrong and the one server is the correct way to go. Any help is appreciated.
Thanks,
