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 04 '11 at 01:18

  • Note, whatsmydns.net has the option for IPV6 too if you select AAAA records, hadn't really noticed before – jb510 Mar 09 '13 at 21:45
