“WTF!!!” are generally the first words out of anyone’s mouth when they find out their website can no longer be accessed by their users. Some times a geek knows why there is a problem. They know they just migrated their site and they realize that they need to turn on, or off DNS forwarding. But many times folks simply have no idea what has happened.
ViewDNS.info is a surprisingly useful website although it looks like it has been designed by the same imaginative team that came up with Craigslist . Basically ViewDNS.info is a collection of troubleshooting tools all listed on a single page that can be run from the web page.
You can run a Port Scanner, Ping, Traceroute and even see if your site can be accessed from China or Iran. Beyond that you can check to see if your IP address is on any Spam Block lists or find the geographic location of an IP address.
There is nothing on the site that is particularly revolutionary, or that can’t be found somewhere else. What makes ViewDNS.info so valuable is that all the tools are on the one page in an easy to use format.
ViewDNS.info is definitely a website that should be in every geeks toolkit.
