To many people, tracing an IP address probably seems like what you would see in a movie: an elite hacker working on a laptop to expose someone’s physical location, revealing an address in a country halfway around the globe.

As with most things Hollywood, the reality isn’t that glorious or complicated. You’ll never get a specific geolocation on a map. Though it is true that a talented hacker can do a lot of things, anyone can learn to trace an IP address.

Admittedly, the IP address tracing methods we’re going to show you are simple and will only show information about the internet service provider (ISP), city and state. To obtain revealing information, you’d need to employ tactics of dubious legality or get law enforcement involved. That said, there are reasons to learn a simple IP trace.

Learning how to track an IP address is a good way to trace an email or look into the whereabouts of a company or URL. Knowing how to look up an IP address, as well as hide your own IP address, is also part of knowing how to protect your privacy and yourself while using the internet.

Though there are a lot ways to stay safe on the internet, everyone should learn how to trace IP addresses, just like they should learn how to change a tire. In this quick and easy guide, we’ll show you to do it. If you live in the United States, check out our explanation of how to get a U.S. IP address, too.

What Is an IP Address

The “IP” of “IP address” stands for “internet protocol.” If you haven’t checked out our IPv4 vs IPv6 guide, now is a good time to do so because it provides context here.

To us, an IP address looks like a string of letters and numbers, but that strand of characters is how a computer or mobile device using the IP/TCP suite — the internet — is identified online. In other words, an IP address is a unique identification code that gets linked to your online activity.

Many may wonder how trackable an IP address is and if it could lead back to them. The answer is yes and no. Your IP address is trackable down to the city, state and ISP.

Your IP address alone won’t reveal your address or geographical location, though. A talented black-hat hacker could track an end-user to their living room, but they’d be using more than just an IP address.

Find Your Own IP Address

Before attempting to trace someone else’s IP address, it’s fitting to learn how to find your own. There’s a couple of quick and dirty ways to do so: online tools and the command line interface of your preferred operating system. Which you use will come down to preference or convenience.

Find Your IP Address on Windows

  • Press the Windows key + R
  • In the run window, type “cmd” and press enter
  • In the command prompt, type “ipconfig/all” and press enter

On Windows 10, that will provide you with multiple lists of information detailing your connections and network adapters, as well as IPv4 and IPv6 IP addresses. The IP address you’re looking for will say something similar to “IPv4 (preferred).”

Find Your IP Address on macOS

  • Press cmd + space
  • Type “terminal” and press enter
  • In the command window, type “ipconfig”

As it did above, that will return several lines of network information. The IP address you’re looking for is likely under the “en0” section next to “inet.”

Find Your IP Address on Linux

  • Press ctrl + alt + T
  • In the terminal window, type “hostname -I” (that’s a capital “I” as in “India”) and press enter

That should return your IP address. Because Linux is open source and there are many distributions, the method for accessing the command line or your IP address could be different. Generally, the above method should work for Debian, Ubuntu and Mint.   

If you’d rather not dabble in the arcane arts of command line text, you can use IP-lookup web tools, such as

Get IP Addresses From Email

Emails carry the IP addresses of the senders in what is called a header. Email headers are similar to digital envelopes, containing important information about the receiver and sender. We don’t usually see headers because modern email clients hide them by default. They’re there, though, and every client should have an option to view them.

It’s worth mentioning that most popular email services use mail servers, so the IP address in the header will point to a corresponding mail server, rather than the user who sent the message. Still, evaluating the header could help identify spam or phishing attempts and keep your inbox safe.

In Gmail

  • Open the message
  • Select “more” — look for three vertical dots next to the “reply” arrow
  • Click “show original”

In Mail for macOS

  • Go to the message in your inbox
  • Open the “view” menu and select “message”
  • Select “all headers” or “long headers”

Outlook 365 for Windows

  • Double-click the message to open it in a separate window
  • Click “file” then select “properties”
  • Header information will be in the “internet headers” box

Email headers contain complicated blocks of data that is usually longer than the message itself. To get an IP address, you’re looking for “received” lines. Alternatively, you can copy the header and paste it into a header analyzer, such as this one from Google. Another one can be found at

Get IP Addresses Using Command Prompt

There are a couple of ways to track an IP address with command line tools. The simplest is the “ping” command. It allows your computer to ping a host and receive a reply. In doing so, you’ll get the IP address of that host.


  • Press the Windows key + R
  • In the run window, type “cmd” and press enter
  • In the command prompt, type “ping host hame” (for example: “ping”)
  • If the connection is successful, it will return an IP address for the host


  • Press cmd + space
  • Type “terminal” and press enter
  • In the terminal window, type “ping host name”

Another powerful command is “netstat,” which is available for macOS and Windows. It will allow you to view active connections across all applications and ports. Netstat can be used with several syntax options to filter the information it returns, but we’ll spare you those details. Instead, we’ll just run “netstat -an.” That will show all open ports and list addresses.

Before doing this, we recommend closing applications and processes you don’t need. That will help limit output to connections you want to see.


  • Press Windows key + R
  • In the run window, type “cmd” and press enter
  • In the command prompt, type “netstat -an” and press enter


  • Press cmd + space
  • Type “terminal” and press enter
  • In the terminal window, type “netstat -an” and press enter

This will return several lines of text, detailing open ports, IP addresses and connection statuses. You’ll need to sift through them to find the IP address you’re looking for.

Tracing an IP Address

Though you can’t trace an IP address to a physical location or use it to reveal personal information about someone behind a computer, you can use it to get a better idea about a company, URL or email. Below, we’ll outline a couple of ways to get more information once you have an IP address.

First, we’ll use another command via your command line interface. It is called “tracert” or “traceroute.” Route tracing is commonly used to find real IP addresses through proxies. (Using a proxy is the easiest way to hide your IP address, and you can read our best free proxy guide for more information.) 

Route tracing is available on Windows and macOS devices, it and allows you to get detailed information about network paths. Like the aforementioned “netstat,” it comes with several syntax options for augmenting results, but we’ll keep it simple.

In the instructions below, “IP address” means the numerical IP address you want to trace. You can also insert a URL.


  • Press the Windows key + R
  • In the run window, type “cmd” and press enter
  • In command prompt, type “tracert IP address”


  • Press cmd + space
  • Type “terminal” and press enter
  • In the terminal window, type “traceroute IP address”

Another method is to take an IP address and use an online lookup tool, such as the one at the website, and clicking “IP lookup.” Paste the IP address into the search bar, then click “get IP details.”

The Whois Lookup by Domain Tools is also a great resource. There, you can insert an IP address or domain name and get detailed information — even an email address you can report abuse to.

Final Thoughts

If all that sounds unnerving, don’t worry. There’s little personal data to be had with just an IP address. Still, there are plenty of other reasons you might not want your IP address out there. They include ISP snooping, web tracking, content blocking and targeted ads, just to name a few. Covering your digital footprint is easy and never a bad idea.

The best way to hide your IP address is to use a virtual private network. We routinely test and update our list of the best VPN providers, so you’ll want to start there, or we can just send you to our ExpressVPN review because it is our all-around favorite service.

You could also use a browser like Tor, which will also obscure your IP address to an extent, but this browser isn’t a perfect solution. To learn more about the Tor browser and anonymous browsing, read our anonymous browsing guide and our VPN vs proxy vs Tor guide.
