Networking Basics: Understanding IPs, DNS, and VPNs

Networking is the backbone of modern IT. Let’s break down three fundamental concepts: IPs, DNS, and VPNs.

1. What is an IP Address?

An IP (Internet Protocol) address uniquely identifies a device on a network. It can be IPv4 (e.g., 192.168.1.1) or IPv6 (e.g., 2001:db8::ff00:42:8329).

2. Understanding DNS (Domain Name System)

DNS translates human-friendly domain names like example.com into IP addresses that computers understand.

3. What is a VPN (Virtual Private Network)?

A VPN encrypts your internet connection, providing privacy and security, especially for remote work.

Conclusion: Understanding these basics helps IT professionals configure and secure networks effectively.
