Google Public DNS

I just read an article about Google publishing a Public DNS service. Google Public DNS is a free, global DNS resolution service. Google recommends using their Public DNS server as an alternative to your current DNS servers.

To try it out:

  • Configure your network settings to use the IP addresses and as your DNS server

More information about Google’s Public DNS can be found here.

I will be using Google’s DNS service for testing purposes, because I cannot imagine using them as primary DNS. There are a lot of questions, like:

  • Performance
  • Support

Maybe I will use them as third or fourth DNS forwarders after the DNS servers from my provider.
