Your IP address is a unique identifier issued by your Internet service provider. An IP address from Charter Communications will have the same format as an IP address issued by any other Internet provider, for example “192.168.100.100.” Each set of numbers in between each period can be anywhere from one to three integers. Many Web services use your unique IP to authenticate you as a user of your machine. Changing your IP can help to reset some of these authentication settings and make your computer appear as a fresh, new device to whatever network you are connecting to.
