Re: Google DNS --- Figuring out which DNS Cluster you are using

Gee Chris, that's kind of an asinine response. Erik took the time to let us know about what he had found out, with a nice code snippet too. I don't have time in my job to just go surfing around google.com to see what is there. His mail took me about 2 minutes to read and now I know that such

Re: Google DNS --- Figuring out which DNS Cluster you are using

Google DNS --- Figuring out which DNS Cluster you are using

I sent this out on the outage list, with a lots of good feedback sent to me. So I figured it would be useful to share the information on nanog as well. A couple months ago had to troubleshoot a google DNS issue with Google’s NOC. Below is some helpful information on how to determine which DNS
