What is an IP Address?
An IP (Internet Protocol) address is an addressing system that allows devices to communicate with each other on the internet. Each device is assigned a unique IP address when it connects to the internet. This address is essential for devices to exchange data with each other.
IP addresses come in two main types:
- IPv4: Composed of four numbers separated by dots, like 192.168.1.1.
- IPv6: Longer and more complex addresses like 2001:0db8::1428:57ab.
IP addresses are vital for the internet to function. Data packets reach their destination through these addresses.
