Google has set-up DNS Resolving Service couple days before. I used for days and it is great!
For those who don't know. The Server address is:

8.8.8.8 
.or.
8.8.4.4

This shall be an impact to another DNS provider, OpenDNS, since they earns alot from those Ads in their unknown-host page.
OpenDNS DNS Server:

208.67.222.222
.or.
208.67.220.220

Fellow Gentooers. Code snippet in my /etc/conf.d/net (DSL by PPPoE, change to meet your device)

dns_servers_ppp0="8.8.8.8 8.8.4.4 208.67.222.222 208.67.220.220"
