extraDNS: does it work?

Do you think this works, or is yet another time waster?

ExtraDNS saves time by intercepting DNS requests and storing replies in a fast, indexed database. The next time your system needs to resolve the same address, ExtraDNS instantly supplies the reply from its database. This decreases delays when loading a Web page (it also has to resolve addresses for the graphics, banners, and other elements of the page).

All IP numbers are not stored on every DNS server, and browsers usually search for them one by one to resolve the URL. ExtraDNS further speeds up the search process by searching many DNS servers simultaneously.

Theorycraft: Apparently your OS does the same thing so the improved speed will be either in a faster implementation or a longer caching time of the responses. If it was free I'd give it a try but not worth paying money for I'd say.

I second that. And if it caches responses longer than the OS, perhaps it caches them longer than the expiry time sent by the DNS server... that's a BAD idea.

If you don't think windows' DNS cache is good enough, google for treewalk DNS, that might float your boat. And it's free.

I wouldn't pay for DNS lookups.
