Designing a high availability DNS resolver?
Greetings,
I've got two DNS resolvers (no zone files) on IP's 10.100.0.8 and 10.100.0.9.
The DNS clients on the network some have 10.100.0.8 and 10.100.0.9 but some don't have both included (former management) out of about 500 machines.
So I need some sort of high availability that will listen on both IP's and will failover (and bind to the failed IP) should one of the DNS servers not resolve something after X amount of time.
Any of you guys know of any solutions out there; or if it's been done before?
I could program something; but it'd take quite a while to do.
