IPWhat Is My IPv4 Address and How to Find It?
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:
- Press Windows key + R
- Type cmd and press Enter
- Type ipconfig and press Enter
- Look for "IPv4 Address" under your active network adapter
- The number next to it (e.g., 192.168.1.5) is your private IPv4
On Mac:
- Click Apple Menu >; System Preferences
- Click Network
- Select your active connection (Wi-Fi or Ethernet)
- Your IPv4 address appears in the main panel
On iPhone / iPad (iOS):
- Open Settings
- Tap Wi-Fi
- Tap the (i) icon next to your connected network
- Look for "IP Address" — this is your private IPv4
On Android:
- Go to Settings
- Tap About Phone or About Device
- Tap Status or Network
- 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.
Frequently Asked Questions
What is an IPv4 address?
An IPv4 address is a 32-bit numerical label assigned to a device on a network, written as four decimal numbers separated by dots (e.g., 192.168.1.1).
What does IPv4 stand for?
IPv4 stands for Internet Protocol version 4, the fourth version of the Internet Protocol used to identify devices on a network.
How do I check my IPv4 address?
You can check your public IPv4 by visiting iptrackertools.com/my-ipv4-address or use system settings (like ipconfig on Windows) to find your private IPv4.
What is the difference between public and private IPv4?
A public IPv4 is assigned by your ISP and visible on the internet, while a private IPv4 is assigned by your router and used within your local network.
Can two devices have the same IPv4 address?
Yes, devices can share the same public IPv4 through NAT, but each device on a local network has a unique private IPv4.
Why is IPv4 running out?
IPv4 has a limited number of about 4.3 billion addresses, and the rapid increase in internet-connected devices has exhausted most of them.
What is IPv6 and how is it different from IPv4?
IPv6 is a newer version of the Internet Protocol with a much larger address space, using a different format with colons instead of dots.
How can I find my IPv4 on Windows?
Open Command Prompt, type ipconfig, and look for "IPv4 Address" under your active network adapter.
How can I find my IPv4 on mobile devices?
On iPhone or Android, go to Wi-Fi settings and check the IP Address field under your connected network.
Do I always have an IPv4 address?
Yes, most devices still have an IPv4 address, often alongside an IPv6 address in modern networks.
When do I need my IPv4 address?
You need it for tasks like port forwarding, setting firewall rules, troubleshooting networks, gaming servers, or verifying VPN connections.
Is my IPv4 address permanent?
Not always, most ISPs assign dynamic IPv4 addresses that can change over time unless you have a static IP.
Is it safe to share my IPv4 address?
Generally, sharing your public IPv4 is not highly dangerous, but it can expose your approximate location and network, so it’s best to be cautious.
