IP address (Internet Protocol address) is a unique numerical label assigned to each device connected to a computer network that uses the Internet Protocol to communicate.Types of IP Addresses
1. IPv4 (Internet Protocol version 4): A 32-bit address that consists of four numbers separated by dots (e.g., 192.0.2.1).
2. IPv6 (Internet Protocol version 6): A 128-bit address that consists of eight groups of four hexadecimal digits separated by colons (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334)
