Hi,
let me introduce to you OpenDNS. It's a free DNS (domain name server) which has got a lot of features that improve your web experience.
First of all, it speeds up your current internet connection, because OpenDNS has a very extensive DNS cache.
It also allows allows you to block domains (custom) or use single content filters (phising, porn...) in one computer or the whole network.
It has an URL correction feature which helps to correct tipos, e.g.: .cmo -> .com
Finally, you can set up shortcuts in your address bar, e.g.: you type 'host', 'http://www.trap17.com/' loads.
I've been using this for a few weeks now and it is really useful. I hope you'll like too!
