What is IP Address

An IP address (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: identifying the host or network interface, and providing the location of the host in the network.

There are two versions of IP addresses in use today: IPv4 and IPv6. IPv4 addresses are 32-bit numbers typically represented in dot-decimal notation (e.g., An IPv4 address is divided into two parts: the network address and the host address. The network address is used to identify the network, and the host address is used to identify a specific device on that network.

IPv6 addresses, on the other hand, are 128-bit numbers represented in hexadecimal notation, separated by colons (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334). IPv6 addresses are divided into two parts: the 64-bit network prefix and the 64-bit interface identifier. The network prefix identifies the network, and the interface identifier identifies a specific device on that network.

An IP address can be either static or dynamic. A static IP address is one that is manually configured and does not change. A dynamic IP address, on the other hand, is one that is assigned automatically by a DHCP (Dynamic Host Configuration Protocol) server.

IP addresses are important because they allow devices to communicate with each other over a network, and they allow devices to connect to the internet. They also provide a way for network administrators to manage and organize devices on a network, and to control access to the network.

It's important to note that IP addresses are not permanent and are assigned by Internet Service Providers (ISPs), and may change periodically.
