How to Find the IP Address of Your Computer

An IP address is a unique identification number given to your computer when it is connected to a network. There are two types of networks that you can connect to — private and public. When connecting to the internet, your computer receives a public IP address.

When connecting to a local area network (LAN), such as your home network made up of your own devices, your computer gets a private IP address.

Public IP Address

Finding out your public IP address is really simple. You can Google it or use another web based service to find it:

Google result for 'my ip'

Google result for ‘my ip’

Private IP Address

To find the private IP address of your computer, you can use Command Prompt or the Control Panel.

The Command Prompt Way

Launch Command Prompt via Start > All Programs > Accessories.

In Command Prompt’s window, type and enter the following command:

The output will look something like this:

ipconfig results in Command Prompt

ipconfig results in Command Prompt

Look for a line called IPv4 Address — that’s your private IP address.

The Control Panel Way

Go to Control Panel > Network and Internet > Network and Sharing Center.

In the View your active networks section, click on the link next to Connections:.

View your basic network information and set up connections

Then, in the Network Connection Status window click on the Details… button.

And, finally, in the Network Connection Details window, find the line saying IPv4 Address.

network-connection-details-ipv4-address

Network Connection Details

That’s your private IP address.

Router Lookup

You can also look up both your public and private IP addresses via accessing your router’s settings.

Open your browser, then type and enter your router’s address.

Usually, it’s one of the following:

If it’s none of the above, ask your internet service provider (ISP) for the correct address.

You will probably need a user name and password to access your router’s settings. If not, you should set it up, so that they are required. It is really not secure to allow access to your router to anyone.

I can look up my public IP address using my Cisco router’s page at Status > Gateway:

Router status — IP address

Router status — IP address lookup

And to look up my private IP address, I go to Status > Local Network:

Router status — IP address lookup (alternative way)

Router status — IP address lookup (alternative way)

The layout of the router’s page will be slightly different for each vendor. But the basic concept will be very similar.
