After having it on my site for over a year, I have exposed the GrabIP API (I can’t believe I have a something I can even call an API) for random IP Address checks. Simply send a request to the system in the following format, and it will tell you which IP Block it resides in.

The database is not as precise as some of the other ones that are available, but it was never designed as a tool of precision. I wanted a way to determine where visitors to my site were coming from, and I didn’t need the level of detail available in some of the for-fee IP lookup databases.

A somewhat outdated write-up on the GrabIP system is available here.

I will be exposing the GrabIT2 API soon.
