Speaking of using a DNS proxy, does anybody know of anybody else doing this besides Foundry??
Radware's WSD (Web Server Director) plays DNS server for clients wanting to resolve a hostname to the IP of a close (from a network latency perspective) server farm.
It isn't a DNS proxy, though. It's acting as the authoritative DNS server for specific hostnames delegated to it by the servers authoritative for the parent zone.
Resonate does that, too. And so does Cisco's global Director (I think).
Is that what you were after?

Kind of. What we're trying to do here is provide a back-up only approach for Internet service via NAT and VRRP/HSRP at the customer premise. The problem is with people hosting applications on-site that require DNS (www,MX,etc.). Trying to avoid using BGP as a back-up mechanism in this case (for obvious reasons), if I could find a product that could act as a authoritative DNS with a TTL of 0 or something, and only send replies for applications when the primary IP was down or unreachable, and then statically NAT our address over to the primary address at the customer premise, I think we could have a pretty good solution for providing back-up Internet service, including web, mail, etc. applications. I will definitely take a look at all the listed products and would appreciate anyone's input on this matter. Thanks! Brantley
radware also had that rather original triangle data flow mechanism i mentioned. frankly speaking, i don't know what happened to it. in its intact form, it doesn't work anyway. -- dima.
