Where can I get a free domain name?

You can get a free domain at .TK registry: http://www.dot.tk/en/index.html

These are known to be spammy, though.

Hi, There are large number of domain registrar ,who can provide a domain for your website.But mostly free domain registrar would be providing sub domains.So instead of getting a domain for free just get a paid domain .By getting a paid domain name you will get your own domain.If you are interested in getting a paid domain ,you can use the site http://www.9cubehosting.com/cheap_domains/.
