Thanks a lot for raising it! I will get it fixed quickly.
What you think of the service overall?
The JSON output looks comprehensive though I dug that out from the browser's developer console; when using the form on the frontpage, I run into CORS issues -- if you pop the browser's console, it becomes self-explanatory.
Thanks. I put a lot of effort in building an API which would expose as much IP related data as possible and and at the same time which would have a fast response time.
I will look into this CORS issue. Thanks for pointing that out.
FYI the CORS issue has been solved. Thanks again for reporting.
