OpenDNS seems good
OpenDNS provide DNS servers that they claim are faster than the ones your ISP provide. I’d have to say I agree. They’re probably also more reliable. I’m trying them out at work today, and I’ll probably give them a go at home. Seems like a cool idea anyway — they have servers is various locations around the US, and now in London. (No servers in Australia though, so probably won’t provide massive gains there, unless your ISP is really crap.)
They also block phishing sites, and do typo correction (e.g. “bellyphant.cmo” => “bellyphant.com”). They also do a search if you type in a totally wrong domain name that they can’t fix — this is where they make their money (they show advertisements). I think you can turn all these features off though.
It seems like a good idea to me. Anything that makes the internet slightly faster is good!
