An IP Address (Internet Protocol Address) is a unique identifier assigned to each device on a network. Thus, allowing it to communicate with other devices. It serves as both the address and the location of the device. Similar to how a street address works for mail delivery. There are two main types of IP addresses: IPv4 and IPv6.

IPv4 is the most used version and consists of four sets of numbers (octets) separated by periods, such as 192.168.1.1. It supports about 4.3 billion unique addresses, but due to the increasing number of devices, IPv4 addresses are becoming exhausted.

IPv6 was introduced to solve this issue by providing a much larger address space. It uses eight groups of four hexadecimal digits separated by colons, like 2001:0db8:85a3:0000:0000:8a2e:0370:7334. This allows for a virtually unlimited number of addresses. Ensuring that future devices can be connected to the internet without running out of address space.
