What is the best advice for handling network and internet DNS routing?
Posted on 2007-08-08
I have a DNS Server that an outside company configured. Today, all outgoing www traffic stopped dead. Our computers are all configured to send DNS requests to that server at 192.168.100.2. I quickly figured that since we were still receiving email and our VPN was still up that it was a DNS problem and not that our T1 data line hadn't gone out. So I looked in DNS and our www record appeared to have the address of our old email server instead of the internet DNS server that we use. I replaced the address in the www record with a valid DNS server address.
1. Is it correct to say that that mail server had been handling all of our internet DNS requests?
2. Can I add multiple www records for other DNS servers or is there no point?
3. Since we have DHCP running, would it be better to not use the www record and just set up DHCP to hand out the 192.168.100.2 network DNS server address and also the internet DNS servers?
