Google declared their free DNS service, Google public DNS:
To try it out: Configure your network settings to use the IP addresses 126.96.36.199 and 188.8.131.52 as your DNS servers.

By using Google Public DNS you can:
- Speed up your browsing experience.
- Improve your security.
- Get the results you expect with absolutely no redirection.
What do you think about it? Should I use those DNS servers? One reason to use them is I cannot open the web sites banned by the government (such as YouTube!).
