This page displays the public IP address assigned to your computer. This shows the IPV4 address. To view IPV6, open command prompt & use the command ipconfig. Along with IPV6 public IP address, this command will display even the local IP address if your computer is connected to internet through a router or switching device.

What is my IP?

It is also called as Internet Protocol Address. It is assigned by your Internet Service Provider. The whole purpose of IP address is to uniquely identify any device in the network. There are 2 possible IP addresses that can be assigned to a device connected to internet.

Local IP Address - assigned by router or switch
Public IP Address - assigned by ISP

These IP addresses ensure that internet data queries (in other words Internet data packets) & responses are sent to & received by correct devices in the network (or Internet). It is similar to the way the mail system works. Based on the person address, the postal system deliver the mail to the correct person. An IP address is assigned to a networking device attached to the computer rather than addressing the computer itself. Related Topic: Ip Address Related Topic - Find Local Ip Address
