What is an IP Address, and How Does it Work?

An IP address is a unique identifier assigned to every device connected to the internet. It is a 32-bit or 128-bit binary number that is usually expressed in a human-readable format as a series of four numbers separated by periods (for IPv4) or eight groups of four hexadecimal digits separated by colons (for IPv6).

Every device connected to the internet has an IP address assigned to it, which allows it to communicate with other devices. When you access a website or send an email, your device sends packets of data to the destination device, and these packets are routed across the internet based on their destination IP address.

Different Types of IP Addresses and How They Are Assigned

There are two main types of IP addresses:

  1. IPv4: IPv4 addresses are 32-bit binary numbers that are usually expressed in a human-readable format as a series of four numbers separated by periods. An example of an IPv4 address is 192.168.1.1. IPv4 is the most commonly used IP address format.
  2. IPv6: IPv6 addresses are 128-bit binary numbers that are expressed in a human-readable format as a series of eight groups of four hexadecimal digits separated by colons. An example of an IPv6 address is 2001:0db8:85a3:0000:0000:8a2e:0370:7334. IPv6 is a newer, more advanced format that is gradually replacing IPv4.

What is Dynamic and Static IP Address?

IP addresses can also be classified as dynamic or static. Dynamic IP addresses are assigned by a server using Dynamic Host Configuration Protocol (DHCP), which allows devices to obtain an IP address automatically when they connect to a network. Static IP addresses, on the other hand, are manually assigned by a network administrator and remain the same unless changed manually.

The allocation of IP addresses is managed by the Internet Assigned Numbers Authority (IANA), which assigns blocks of IP addresses to Regional Internet Registries (RIRs) such as ARIN, RIPE, and APNIC. The RIRs then assign blocks of IP addresses to Internet Service Providers (ISPs) and other organizations, which in turn allocate them to individual devices. The allocation process also involves managing IP address space to prevent overlap or conflicts, ensuring that each device has a unique IP address.
