Yes, I am aware that at this point there are hundreds of websites that offer you to lookup your IP and such.

But how much of those domains do you actually remember, and don't have to google all the time to find them?

That's where WhatIsMy.Online comes in. An easy to remember domain name, and using the URL structure incredibly easy to get the information that you want, without having to google it.

Even better, I specifically designed it to work great with APIs. Need the data in a certain format? Just provide the content-type in the Accept header.
