When you type in google.com in the address bar of your browser, it goes to a Domain Name Server to look up the ip address then takes you to the site. This is completely transparent to you, the user.
OpenDNS replaces your current DNS. Configuring it takes about 30 seconds and is free. It will block you from going to phishing and other such nasty sites. This alone makes it worth it.
But there’s more! It’s extremely fast (they serve about one billion DNS requests a day) and you can create shortcuts (like “goog” to go to google ) plus it automatically corrects typos.
They currently have four locations in the US, one in London, and more coming.
