How to know someone IP

Can we hack someone by using IP ?

An ip address will do nothing, it will not reveal your email password or anything of that sort. The only thing that an ip address tells someone is the type of your internet provider.

The only thing I can think of that is happening is maybe its someone you know that is changing it. It could be someone that knows your password, and if that is not possible, then it could be a neighbor. If you have a wireless router set up with your internet then it could actually be that someone is intercepting your data.

(If you do not know if you have a wireless router, follow the internet line from your computer untill you get to a box, if that box has an antenna, then you have a wireless router. If there is no line comming from your computer, then you have a wireless connection. If there is no antenna on your box, then it is probibly not wireless, however... it is still possible.)

The easiest way to prevent someone from taking data from your wireless connection is to set up a password. If you type your router's ip address in your address bar, there should be a page from your router come up on the screen, and you can change it from there.

(If you do not know your ip address then go to "My Network Connections" and right click on your connection then click on status, then click on support, then click details. Your servers ip adress will be called "Default Gateway"(I think) and it will have a number like 192.168.1.1)

 The easiest way to obtain the Yahoo messenger IP address is to get that person to send you an email. Then, you can view the header of the email. The header will contain your IP address as well as the sender of the email.
