When your ISP DNS fail -- use Public DNS

Imagine that when your ISP DNS fail, you will find no where to access website, because we are relying very heavy on DNS. So in this case you should find an alternative DNS.

1. Google Public DNS: 8.8.8.8, 8.8.4.4
2. OpenDNS: 208.67.222.222, 208.67.220.220
3. Symantec DNS: 198.153.192.1, 198.153.194.1



I prefer Google Public DNS, because it is very easy to remember. I have one experienced when my school DNS fails no body can access website, but I can because I know the address of Google Public DNS. So start to remember it, someday it will help you.
