What is an IP Address?

An IP address is a unique identifier assigned to a device on a network. It is used to communicate with other devices on the network. There are two main types of IP addresses:

• IPv4 (Internet Protocol version 4): This is the most widely used type of IP address, which is 32-bit in length and separated by dots (e.g., 192.168.1.1).
• IPv6 (Internet Protocol version 6): This is a newer type of IP address, which is 128-bit in length and usually written in a format like 2001:0db8:85a3:0000:0000:8a2e:0370:<prefix>.

Why Check Your IP Address?
