You will find here several tools I find useful. I wanted to have them on my blog so I don't have to search the internet for the information. More importantly, I know that what I will get will be error free and can be trusted (no ads here).
What is my IP?
This page displays your IP and several other information: continent code and name, country code, name and capital, region code and name, city, zip code, latitude, longitude and metro code (depending on your IP some information may not be available).
