Understanding IP Addresses
Before diving into the practical steps, let’s start with the basics. An IP address (Internet Protocol address) is a unique string of numbers separated by periods or colons that identifies each computer using the Internet Protocol to communicate over a network. Think of an IP address as the unique phone number that allows other devices to locate and connect to your laptop within a network. There are two types of IP addresses: IPv4 and IPv6.
Types of IP Addresses
IPv4
IPv4 addresses consist of four sets of numbers ranging from 0 to 255, separated by periods (e.g., 192.168.1.1). This is the most common format used in homes and businesses.
IPv6
IPv6 addresses are the newer format designed to accommodate the growing number of devices connected to the internet. They consist of eight groups of four hexadecimal digits (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334). While less common on personal devices, it is becoming increasingly important as IPv4 addresses become scarce.
