An IP address, which stands for Internet Protocol address, is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. IP addresses serve two primary functions:
Host or Network Identification: They identify a particular device or host on the network. In the context of the Internet, every device that connects to the Internet, including your computer, smartphone, or web server, is assigned a unique IP address. This address is used to locate and communicate with the device on the network.
Routing: IP addresses are essential for routing data packets between devices on a network and between different networks on the Internet. Routers and other networking devices use IP addresses to determine where to send data packets so they reach their destination.
There are two primary versions of IP addresses in use:
IPv4 (Internet Protocol Version 4): This is the most common version and consists of sets of four numbers separated by periods (eg, 192.168.0.1). IPv4 addresses are 32-bit in length and have a limited address space, which has led to exhaustion of available IPv4 addresses in many regions. To alleviate this problem, IPv6 was developed.
IPv6 (Internet Protocol Version 6): IPv6 was introduced to address the limitations of IPv4. IPv6 addresses are 128 bits long and are usually specified in hexadecimal format (eg, 2001:0db8:85a3:0000:0000:8a2e:0370:7334). IPv6 provides a much larger pool of IP addresses, ensuring that the Internet continues to grow and accommodate an increasing number of devices.

IP addresses can be dynamic or static:
Dynamic IP address: These addresses are usually temporarily assigned to devices by a DHCP (Dynamic Host Configuration Protocol) server. They may change periodically when the device reconnects to the network.
Static IP Address: These addresses are configured manually and do not change unless reconfigured by the network administrator. They are often used for servers or devices that require a fixed, unchanging address.
In short, an IP address is a fundamental component of computer networking and is used for device identification and data routing on the Internet and other IP-based networks.
