наш провайдер (Domru.ru) УЖЕ давным давно перехватывает DNS-сообщения от 8.8.8.8/8.8.4.4 .. и в случае чего -- меняет там записи A-типа.
хотя DNS-сообщения от 2001:4860:4860::8888/2001:4860:4860::8844 -- перехватывать не догадались. (Domru.ru выдаёт IPv6 адреса своим клиентам тоже)
вот доказательства:
$ host -v 2chru.net 8.8.8.8
Trying "2chru.net"
