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:

  1. Press Win + R at the same time to open the Run box.
  2. Type “CMD” and press Enter.
  3. In the Command Prompt, type “IPCONFIG” and press Enter.
  4. 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):

    1. Open the Apple menu and choose System Settings.
    2. Select Network.
    3. Choose your active connection (Wi-Fi or Ethernet).
    4. 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.
