Yandex, the Russian search services provider gives free Public DNS. It has three categories: Basic - No filtering Safe - Malware and fraudulent sites filtering Adult - Safe + Adult sites & adult ads filtering. I am trying it and for now the block pages appear in Russian. Website: http://dns.yandex.com Technical details: http://dns.yandex.com/advanced/ They say something about family search. I don't know how to activate it. Probably it works with only Yandex search. EDIT: Terms of use is not yet updated in English website. But it is given in Russian site: http://legal.yandex.ru/dns_termsofuse/ Using google translate
At present I am not using it as it is slow for me. The block page looked the same as given in this Russian site which has reviewed it: -http://i-notes.org/yandex-dns-servera/-
