You can also add .surf to the end of any .bit address on any computer. eg. http://zerotorrent.bit can be accessed via https://zerotorrent.bit.surf from regular DNS.
Note: Using a web proxy doesn't have the full security features of viewing dot-bit domains from the Namecoin blockchain resident on your own machine (or your own DNS server). A proxy can be compromised or hijacked with a man-in-the-middle attack. It can also be taken down by a number of methods. Click here to find out more

http://bit.surf/ is a Namecoin web proxy. It allows you to view .bit domains (Namecoin domains) without installing any software. It's kind of like "training wheels for Dot-Bit." We're offering this service free as a labor of love because we believe in Namecoin and believe in the open-Internet anti-censorship and better security features of Dot-Bit domains over standard ICANN-controlled domains. (.com, .net, .eu, etc.)
This proxy has the advantage of you not needing to install anything. But it doesn't have the full security features of viewing dot-bit domains from the Namecoin blockchain resident on your own machine. A proxy can be compromised or hijacked with a man-in-the-middle attack. It can also be taken down by a number of methods. Not so when using the blockchain on your own machine.
If you'd like to use the full range of protection of resident blockchain dot-bit viewing, please download MeowBit or FreeSpeechMe and follow the directions. Both are free (no cost) and free software (open source / GNU licensed.)

You can also use the service by just appending .surf to the end of any .bit address. eg. http://nx.bit can be accessed via http://nx.bit.surf from regular DNS.
This was previously built on a slightly modified version of knProxy+ Namecoin + NMControl
