Are you looking for a domain that look professional for free? Well there are many place you can go to get it. But my favorite is at http://freedns.afraid.org . Afraid.org is a free DNS service where everyone can share their domains with other. By having an account in freedns.afraid.org you can obtain many great domains that were shared by other people. In my opinion many of them were weird, but some of them look professional. Like the one i uses for this site (.info.tm). You can also have other good domains like .biz.tm , .shop.tm, .edu.ms and .pro.vg. You can use those subdomains and host them anywhere you want for free!

There are other free sevice that also offer you free domain like .co.nr , .biz.ly, and some domains offer by v3.com like .i.am , .go.to, etc. But they only offer URL redirection for those subdomain, the others offering free domain only if you host those domain with them.
