Local and Public IP Addresses: What You Need to Know
Your computer has two types of IP addresses:
- Local IP Address
- Public IP Address
Below, you’ll learn the difference, why they matter, and how to find each one.
What is a Local IP Address?
Your Local IP Address is assigned by your router or firewall and is used only inside your private network.
Think of it like this:
- Public IP Address: The hotel’s street address (everyone sees it)
- Local IP Address: Your room number inside the hotel (only used internally and likely that multiple hotels will use the same room numbers)
Public IP Address:
- Assigned by your Internet Service Provider (ISP)
- Your Public IP is the IP Address given to your Modem by your Internet Service Provider, and is unique in the world (like “1234 Main St, New York, NY – USA”)
Local IP Address:
- Assigned by your router or modem (they are often one and the same device), or Acumera Firewall
- Not globally unique (like “Room 1234”)
- In your case, the Local IP is given to your computer by your Acumera Firewall.
Can’t I just google it?
Well, yes and no. You can Google your Public IP, but you cannot Google your Local IP.
Here’s why:
Using the above hotel analogy, if you call a restaurant and order food, the restaurant sees the Hotel’s caller-ID, but they cannot see your room number.
Similarly, when you ask Google what your IP address is, Google will see your Public IP. That being said, there is a link in the next section to a web page that may show you your Private IP, depending on your computer. If that doesn’t work, don’t worry: we have instructions for finding a local IP on Windows and Mac as well.
How to Find Your Local IP Address
First, try the easy way:
- Click Here. If you are not able to use the link, follow these steps:
On Windows 10, 11:
- Press Win + R at the same time to open the Run box.
- Type “CMD” and press Enter.
- In the Command Prompt, type “IPCONFIG” and press Enter.
- Look for IPv4 Address.
- It will look like 192.168.xxx.xxx or 10.10.xx.xx (where the x’s represent your unique numbers).

On MacOS (Latest Version):
- Open the Apple menu and choose System Settings.
- Select Network.
- Choose your active connection (Wi-Fi or Ethernet).
- Your IP address will be shown on the right.
How do I find my Public IP Address?
- The easiest way is to simply Google it (you can use any search engine).
- If you’re not able to find it that way, you can call your Internet Service Provider or the Acumera Technical Support Team for assistance.
