DotTK offers free .tk domain names, as well as paid .tk domain names ($6.95/year). The free domainâ€™s come with a twist though – a Free .TK Domain automatically expires when it does not receive the required minimum of 25 unique visitors during the previous 90 day period. DotTK supports frame redirects, and also allows you to use your own name servers to seamlessly integrate your .TK domain into your website. DotTK also offers their own DNS service in-case youâ€™d rather use that. If you do not set your website to properly redirect or if the DNS is still updating your .TK domain will display a parking page with advertisements.
