How to view where DNS has propagated all over the world

I just wanted to quickly share a nice tool that I use all of the time when transferring sites to different servers or just changing DNS entries. Sometimes it's hard to tell how long or if the DNS for your domain has updated in other regions in the world. In this case, I use WhatsMyDns.net. It's a neat tool that allows you to look up the current DNS listing for common entries (I really only ever need to use A or CNAME) in quite a few servers located around the world. Since DNS propagates differently by geographic region, this tool is a very good overview as to how users are accessing your site.

Also, if you're like me and constantly need to check your IP address and don't want to always search google for "whats is my ip", I'd recommend you bookmark whats my info, a simple, non-bloated site that gives you what just you're looking for.
