how much can be learned from my ip address?

How much personal information really can be learned if someone just has my computers I.P. address? Since people say I.P. address is not personally identifiable, but can it be possible that it is?

 

Hi,
If you have static ip and somehow you volunteer info that someone can use piece by piece to try to assemble a picture of you. But otherwise, no meaning to it.

They can learn nothing more than where you are (which country in the world, or rather the country of your ISP) and your ISP's details. Other than that, nothing about you yourself.

Unless you have chosen to register a range of static IP addresses with the authorities, in which case they can learn more about you from the entries in the register held by organisations such as ARIN and RIPE, who operate with ICANN.
