Is it possible to have redundant DNS? What I am thinking of is having two completely different ISP's provide two different Internet connections to an office. The idea is that if one goes down the other will be available. I am trying to figure out however when that happens how would remote folks looking to access home.com by DNS name be able to as the DNS for that would be assigned to one of the static IP's via a DNS provider. Could I have same DNS name point to two different static IP's? Could I use a service like DYNDNS to do this?
