I've always used the LOC to Maps web page to check to see whether my DNS LOC records work properly. I decided to try to rewrite this application using modern web technologies to see how well it would work.
The result is my DNS LOC lookup page. This page is all done with Javascript and XML-RPC and Google Maps with a Python XML-RPC back-end.
Some names to try might be:
- hewgill.net
- macnugget.org
- ivo.nu
- yahoo.com
Let me know whether it works for you and if you find any problems!
