Server Fault is a question and answer site for system and network administrators. It's 100% free, no registration required.

Is there a desktop or online tool that will query multiple name servers (dozens ideally) to get an idea if and how a DNS record change is propagating?

I know of many free tools, but they only check one name server. I'm thinking something more along the lines of the awesome namebench utility.

Maybe I don't understand it well enough, but I get frustrated sometimes after making changes and not knowing if they are propagating properly.

Be sure to set the TTL to the time you want it to take to propogate everywhere ahead of time. If somebody asks the dns server for a result, and the TTL has expired, the dns server should check again. – becomingwisest Feb 4 '11 at 1:18
