Last week I needed to check a large number of sites to see how many of them were still hosted by my employer’s legacy system. After clicking through about 80 of them I realized it would have been much smarter to just ping them and see what IP address they were living at. I looked for a tool that would do that for me, but didn’t find one that would accept a list of domains and look them all up at once. So I made one.
DomainToIPConverter.com may be a new favorite among my tiny web apps. It accepts a list of host names and looks up the IP address of the server each is pointing to. That’s it. Please enjoy this potentially useful app that does exactly one thing.
