An Internet Protocol (IP) address is a numerical label assigned to each device such as PC, tablet or smartphone connected to a computer network that uses the Internet Protocol for communication. Any device that is connected to the IP network must have a unique IP address within the network.
The IP address serves two main functions:
-
Host or network interface identification.
-
Location addressing.
We all are familiar with the postal address which is used to deliver a postal mail to your home. Similarly, an IP address is a numerical address that can be accessed over the Internet which signifies the globally unique IP address assigned to a computing device.
The public IP address is assigned to a computing device to allow direct access over the Internet and it’s globally unique. The private IP address is the address space allocated by the Network Information Center (InterNIC) to allow organisations to create their own private network.
Why do I need to know my IP address?
If you know your IP address, it can help you in troubleshooting many network problems and other Internet connection issues.
