What Is My IPv4 Address and How to Find It?

Updated April 19, 2026 · 4 min read

If you have searched "what is my IPv4 address," you are in the right place. IPv4 is the most common type of IP address used on the internet today, and understanding it helps you with everything from network setup to security. This guide explains exactly what IPv4 is and how to find yours in seconds.

WHAT DOES IPV4 MEAN?

IPv4 stands for Internet Protocol version 4. It is the fourth revision of the Internet Protocol and has been the foundation of internet communication since the early 1980s. An IPv4 address is a 32-bit number written as four groups of decimal numbers separated by dots.

Example: 192.168.1.1 or 203.0.113.45

Each of the four groups (called octets) can range from 0 to 255. This means there are about 4.3 billion possible IPv4 addresses. While that sounds like a lot, the rapid growth of internet-connected devices has nearly exhausted this supply — which is why IPv6 was developed.

WHAT DOES MY IPV4 ADDRESS LOOK LIKE?

Your IPv4 address always follows this format:

[0-255].[0-255].[0-255].[0-255]

Real examples of valid IPv4 addresses:

  • 8.8.8.8 (Google's public DNS server)
  • 192.168.0.1 (typical home router)
  • 103.21.244.0 (Cloudflare)

If you see a long string of letters and numbers separated by colons, that is an IPv6 address — a different format explained below.

HOW TO FIND YOUR IPV4 ADDRESS RIGHT NOW

The fastest method: visit

Your public IPv4 address will appear instantly on screen with no signup needed.

Alternatively, use
iptrackertools.com/what-is-my-ip

which shows both your IPv4 and IPv6 simultaneously.

FINDING YOUR IPV4 ON DIFFERENT DEVICES

On Windows 10 / 11:

  1. Press Windows key + R
  2. Type cmd and press Enter
  3. Type ipconfig and press Enter
  4. Look for "IPv4 Address" under your active network adapter
  5. The number next to it (e.g., 192.168.1.5) is your private IPv4

On Mac:

  1. Click Apple Menu >; System Preferences
  2. Click Network
  3. Select your active connection (Wi-Fi or Ethernet)
  4. Your IPv4 address appears in the main panel

On iPhone / iPad (iOS):

  1. Open Settings
  2. Tap Wi-Fi
  3. Tap the (i) icon next to your connected network
  4. Look for "IP Address" — this is your private IPv4

On Android:

  1. Go to Settings
  2. Tap About Phone or About Device
  3. Tap Status or Network
  4. Look for IP Address

Note: These steps show your private IPv4. Your public IPv4 is different — check it at iptrackertools.com.

PUBLIC IPV4 VS PRIVATE IPV4

You have two IPv4 addresses:

Public IPv4: Assigned by your ISP. Visible to the internet. All devices in your home share this one address. Example: 203.0.113.45

Private IPv4: Assigned by your router. Only visible within your home network. Different for each device. Example: 192.168.1.5

When websites say "we have logged your IP address," they mean your public IPv4.

WHY IS IPV4 RUNNING OUT?

IPv4 can only support about 4.3 billion unique addresses. With over 15 billion internet-connected devices in the world today, the math does not work. Regional internet registries began exhausting their IPv4 pools around 2011–2019.

Solutions include:

  • NAT (Network Address Translation): Lets many devices share one public IPv4
  • IPv6: A new addressing system with practically unlimited addresses
  • IP address recycling: ISPs reuse and rotate addresses among customers

IPV4 VS IPV6: WHICH ONE DO YOU HAVE?

Most devices today are "dual-stack," meaning they have both an IPv4 and an IPv6 address. Your network will prefer IPv6 when both the device and the destination server support it.

IPv4 example: 203.0.113.45
IPv6 example: 2001:0db8:85a3:0000:0000:8a2e:0370:7334

IPv4 is still dominant and you will almost certainly have one. IPv6 adoption is growing but not yet universal.

WHEN YOU NEED YOUR IPV4 ADDRESS

Common reasons people look up their IPv4 address:

  • Setting up port forwarding on a router
  • Configuring a firewall or network rule
  • Connecting devices on a local network
  • Whitelisting your IP for a remote server or database
  • Verifying a VPN is working (your public IPv4 should change)
  • Troubleshooting a network connectivity issue
  • Gaming (setting up a dedicated server)

CONCLUSION

Your IPv4 address is the most fundamental identifier your device uses on the internet. It is a simple four-part number that routes all of your internet traffic. Check your public IPv4 instantly at iptrackertools.com/my-ipv4-address, and use your device settings to find your private IPv4 for local network tasks.
