Great DNS testing tool

Since that “other provider” went to a paid model and I am cheap this is a great service to have available.

I just needed to use this to diagnose an issue where a server was misconfigured. The domain registar had the correct IP addrresses for the nameservers, but the local zone on ther server had old ones. While I find the concept of DNS simple enough the ins and out of it can be very confusing in my opinion. It is one of those things that I so rarely need to deal wtih that I have to relearn it every time.
