Jay wants a router that can access the fastest DNS on the net. Leo says that would be a great feature. Steve Gibson has a program that can find them, but Leo doesn't know of any routers that have that built in.
In order for the internet to work, you essentially need a giant phone book. When you enter in a web address, the browser needs the IP address (the equivalent of the phone number) of that particular server. So when you enter in the website, the browser starts "asking around". It first asks the operating system, and if it knows, it will give it the address to get there. If it doesn't, it will next go to the router, and if the router doesn't know, it will query the internet service provider. It will eventually query one of the 13 master domain servers spread out all over the world. This is called DNS, or domain name system. Not all DNS are created equal either. Some may be slower than others, and some may even send you to advertising pages when you type in an address that doesn't exist.
Leo recommends running the DNS Benchmark at grc.com on Windows, or Namebench on Mac. Then he can decide which DNS he wants to use. He could use the DNS from his ISP, or he could choose something else like Google DNS or Leo's choice, OpenDNS.
