What is an IP Address?
An IP address is a fixed length sequence of digits that exclusively identifies computers on networks based on the IP communication protocol, such as the Internet. Each network device is assigned a unique IP address (for example: 220.127.116.11), enabling data transmission to and particular devices.
Without an IP address, services such as Internet browsing, e-mail dispatch and receipt, printing and file transfer would not be possible.
