One crucial aspect of your internet connection is your IP address. In this article, we’ll delve into the world of IP addresses, exploring what they are, how they work, and how to find your IP address for your WiFi connection.
What is an IP Address?
An IP address, or Internet Protocol address, is a unique numerical label assigned to each device connected to a computer network that uses the Internet Protocol to communicate. It’s used to identify and locate devices on a network, allowing data to be transmitted between them. Think of an IP address as a street address for your device, helping other devices on the network find and communicate with it.
Types of IP Addresses
There are two main types of IP addresses: IPv4 and IPv6.
IPv4 Addresses
IPv4 addresses are the original IP addresses used on the internet. They consist of four numbers separated by dots, ranging from 0 to 255. For example, an IPv4 address might look like this: 192.168.1.1. IPv4 addresses are limited, with a maximum of approximately 4.3 billion unique addresses available.
IPv6 Addresses
IPv6 addresses are the newer, more advanced version of IP addresses. They consist of eight groups of four hexadecimal digits separated by colons, providing a much larger address space than IPv4. For example, an IPv6 address might look like this: 2001:0db8:85a3:0000:0000:8a2e:0370:7334. IPv6 addresses are designed to provide a virtually unlimited number of unique addresses.
How Do IP Addresses Work?
When you connect to a network, your device is assigned an IP address by a DHCP (Dynamic Host Configuration Protocol) server. This server assigns an available IP address from a pool of addresses, ensuring that each device on the network has a unique address.
Here’s a step-by-step explanation of how IP addresses work:
- Your device sends a request to the DHCP server to obtain an IP address.
- The DHCP server assigns an available IP address from its pool of addresses.
- The assigned IP address is sent back to your device.
- Your device uses the assigned IP address to communicate with other devices on the network.
