WHAT IS AN IP ADDRESS?

In a massive network like the Internet, how does one computer find another? How does a request know where to go, and how does the reply know where to return?

An IP address is the fundamental identifier used to route data between devices.

WHAT YOU’LL LEARN

  • What an IP address actually is
  • Why computers need network addresses
  • IPv4 vs IPv6 (the transition)
  • Public vs Private IP addresses
  • How devices get an IP (DHCP)
  • How data travels across networks (routing)
  • The relationship between domains and IPs (DNS)
  • Basic troubleshooting commands (ping, ip addr)

WHY IT MATTERS

IP addresses are the postal service of the digital world.

Without them, networking, the internet, and remote administration would be impossible.

Understanding IP addresses means understanding how your computer talks to the rest of the world.
