What is this tool?

This tool is essentially similar to the "dig" tool and is more advanced than our nslookup. When you change your name servers and need to verify your changes are being seen throughout the world the traversal tool looks at what each root server is returning. If any are not correct then all subsequent DNS servers that look up your domain from that root server are going to be getting incorrect information.

How do the results help me?

Displays which DNS servers the world thinks are responsible for your domain and what information they are returning.
