I've been having some reliability issues with my ISP's DNS servers. Does anyone have any experience with OpenDNS or the Level 3 (18.104.22.168 - 22.214.171.124) DNS servers?
OpenDNS appears to have some nice filtering features I may want to use for my kids, but appears to have an annoying redirect for unknown addresses. Not that I can fault them for trying to make a few bucks through the redirect.
I've heard Level 3's servers just return a "page not found" error, which would be more desirable. But it doesn't have the server side filtering.
Also, both use a form of "anycast", which from my understanding redirects requests to fastest available server. Does this have any ill effects on secure sessions like online purchasing where you don't want the POSTDATA lost by switching connections?
