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 organizations 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.
