Understanding IP Addresses

Before we dive into the steps for connecting to your Raspberry Pi, it’s crucial to understand what an IP address is and why it is essential for networking.

What is an IP Address?

An IP address (Internet Protocol address) is a unique numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. An IP address serves two primary functions: identifying the host or network interface and providing the location of the device within the network.

Types of IP Addresses

There are two main types of IP addresses you might encounter:

IPv4: The most commonly used IP address, consisting of four numbers separated by periods (e.g., 192.168.1.1).
IPv6: A newer version designed to replace IPv4, which uses hexadecimal numbers and colons (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334).

For most home networking scenarios, IPv4 is sufficient.
