In this article, we will delve into the world of Wi-Fi addresses, exploring what they are, why they are important, and most importantly, how to find yours.
Understanding Wi-Fi Addresses
Before we dive into the process of finding your Wi-Fi address, it’s essential to understand what it is and its significance. A Wi-Fi address, also known as the MAC (Media Access Control) address or IP address, is a unique identifier assigned to your device or router. This address allows devices to communicate with each other over a network, ensuring that data is sent to the correct destination. There are two types of Wi-Fi addresses: IP addresses and MAC addresses.
IP Addresses
An IP address is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. IP addresses serve two main functions: they identify the host or network interface and provide the location of the host in the network, allowing data to be routed across the internet. There are two versions of IP addresses: IPv4 and IPv6. IPv4 addresses are 32-bit numbers, typically written in dotted decimal notation, consisting of four numbers separated by dots. IPv6 addresses, on the other hand, are 128-bit numbers, written in hexadecimal notation, making them much longer than IPv4 addresses.
MAC Addresses
A MAC address is a unique identifier assigned to network interfaces for communication at the data link layer of a network segment. MAC addresses are used to identify devices at the data link layer of the OSI model, below the IP layer. They are typically written in hexadecimal format, with six pairs of characters separated by colons. MAC addresses are hardcoded into network interface controllers (NICs) during the manufacturing process and cannot be changed.
