What is an IP address?
An IP address, or Internet Protocol address, is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. It serves two main functions: host or network interface identification and location addressing.

There are two primary types of IP addresses:
- IPv4 (Internet Protocol version 4): This is the older and more widely used version. An IPv4 address consists of a series of four sets of numbers separated by dots (for example, 192.168.0.1).
- IPv6 (Internet Protocol version 6): This is the newer version developed to address the limitations of IPv4, primarily the exhaustion of available addresses. An IPv6 address is longer and includes both numbers and letters, separated by colons (for example, 2001:0db8:85a3:0000:0000:8a2e:0370:7334).

IP addresses are essential for devices to communicate over a network, as they provide a unique identifier for each device. When you connect to the internet, your device is assigned an IP address, allowing it to send and receive data. IP addresses are crucial for activities like browsing the web, sending emails, and other online communications. Additionally, they play a vital role in networking, helping to route data between devices on the internet.
