IP Address

[QUESTION] What is my IP address?
[ANSWER] Example of an IP address:

209.249.20.210

Every computer connected to the Internet has a unique identifier called an IP address. On many networks, the IP address of a computer is always the same. On other networks, a random IP address is assigned each time a computer connects to the network. This is what we are referring to when we ask if you have a static or a dynamic IP address. If a system uses dynamic addressing, the IP can change quite often, but is usually within a close range of numbers
