What Is an IP Address?

Imagine an IP address as your device’s home address on the internet. Each device connected to the web has its own IP, allowing it to send and receive information, like emails or web pages.

There are two main versions of IP addresses: IPv4 and IPv6.

IPv4 vs. IPv6: What’s the Difference?

  • IPv4: The earlier version using 32-bit numbers. We started running out of these addresses due to the huge number of connected devices.
  • IPv6: The newer version with 128-bit addresses, offering an enormous pool of addresses, ensuring we won’t run out anytime soon.

What Types of IP Addresses Are There?

Two main types of IP addresses exist:

  • Static IP: A fixed address, like having the same phone number forever. Useful for servers that need a permanent address.
  • Dynamic IP: Changes over time, like a phone number that updates occasionally. Common for personal devices like laptops or smartphones.

What Is an IP Address For?

IP addresses serve several key functions:

  • Locate devices: Identifies where a device is on a network, like finding a friend’s house on a map.
  • Connect devices: Lets devices “talk” to each other, sending messages or files.
  • Send data: Ensures data you send reaches the correct destination, like addressing a package properly.

Did You Know There Are Different Classes of IP Addresses?

IP addresses are divided into classes based on network size:

  • Class A: For large networks (like a big city).
  • Class B: For medium-sized networks (like a neighborhood).
  • Class C: For small networks (like a single street).
  • Class D: For broadcasting messages to multiple recipients (like a WhatsApp group).
  • Class E: Reserved for experimental and future use.

How Does an IP Address Protect You?

Your IP address can act like a security measure. If someone does something suspicious online, it can be tracked through their IP and blocked, helping keep the internet safer for everyone.
