IP Networking Basics for Beginners

Published: June 15, 2023

An introductory guide to IP networking, covering essential concepts like IP addresses, subnet masks, and how data travels across networks.

What is an IP Address?

An IP (Internet Protocol) address is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. It serves two main functions: host or network interface identification and location addressing.

Understanding Subnets

Subnetting is the practice of dividing a network into two or more smaller networks. This increases routing efficiency, enhances security, and reduces the size of broadcast domains. A subnet mask is used to determine which part of an IP address is the network address and which part is the host address.

How Routing Works

Routing is the process of selecting a path for traffic in a network or between multiple networks. Routers are network devices that forward data packets between computer networks. They perform the traffic directing functions on the Internet.

Mastering these basics is crucial for anyone looking to delve deeper into network administration or cybersecurity.
