How to Locate an IP Address From an Email

Ethan Martinez

Emails can feel like tiny paper planes flying across the internet. But each one may carry a travel sticker. That sticker is hidden inside the email’s full header. If you know where to look, you may find an IP address that helps show where the message came from.

TLDR: To locate an IP address from an email, open the email’s full header and look for lines that say Received. The earliest trusted Received line may show the sender’s mail server IP address. You can then paste that IP into an IP lookup tool to see a rough location. But remember, it may show a server location, not the sender’s house.

First, what is an IP address?

An IP address is like a street address for a device or server on the internet. It looks something like this:

When an email moves from one mail server to another, those servers can leave notes in the header. These notes can include IP addresses. Think of them as footprints in wet cement.

But here is the twist. The IP address you find is often not the sender’s exact device. It may be the IP address of Gmail, Outlook, a company mail server, or a marketing email service.

What is an email header?

An email header is the hidden tech part of an email. You normally see the simple stuff:

But the full header has much more. It can show the route the email took. It can include mail servers, security checks, message IDs, and sometimes IP addresses.

It is a bit like checking the back of a concert ticket. The front is pretty. The back has rules, codes, and tiny text that only detectives enjoy.

Why would you want to locate an IP address?

There are many honest reasons to check an email IP address. For example:

Stay on the safe side. Do not use this information to harass, threaten, or stalk anyone. An IP address is not a treasure map to a person’s sofa. It is usually a clue, not a final answer.

Step 1: Open the full email header

Different email apps hide headers in different places. The good news is that they are usually only a few clicks away.

In Gmail

  1. Open the email.
  2. Click the three dots near the reply button.
  3. Choose Show original.
  4. A new page opens with the full header.

In Outlook on the web

  1. Open the email.
  2. Click the three dots or More actions.
  3. Choose View message source or View message details.
  4. Copy the header text.

In Apple Mail

  1. Open the email.
  2. Click View in the menu.
  3. Choose Message.
  4. Select All Headers or Raw Source.

In Yahoo Mail

  1. Open the email.
  2. Click the three dots.
  3. Choose View raw message.

Now you have the secret scroll. It may look messy. Do not panic. You only need a few parts.

Step 2: Look for “Received” lines

The most useful lines often start with Received:. There may be several of them. That is normal.

Each server that handled the email may add a new Received line. The newest one is usually at the top. The oldest one is usually near the bottom.

Here is a simple example:

Received: from mail.example.com (mail.example.com [203.0.113.24])
by mx.yourmail.com with ESMTP;
Tue, 10 Oct 2026 12:45:09 +0000

In this example, the IP address is:

203.0.113.24

That is the clue you are looking for.

Step 3: Find the earliest trusted IP address

This part matters. Do not just grab the first IP address you see. Email headers are stacked like pancakes.

The top pancake is usually added last. The bottom pancake is usually added first.

So, you may want to start near the bottom and move upward. Look for the first real-looking public IP address in a Received line.

But be careful. Some IP addresses are private. They are used inside local networks. They will not help you locate anything public.

Common private IP ranges include:

If you see those, skip them. They are like “inside the building” room numbers. You want a public street address.

Step 4: Use an IP lookup tool

Once you find a public IP address, copy it. Then paste it into an IP lookup website. Search for terms like:

The tool may show you:

This can be useful. But do not treat it like GPS. IP location can be wrong. Sometimes it shows the location of a data center. Sometimes it shows the office of an internet provider. Sometimes it shows a city hundreds of miles away.

Important: Gmail and Outlook may hide the sender’s IP

Here is the not-so-spicy truth. Many big email services protect user privacy. Gmail, Outlook, Yahoo, and others often do not reveal the sender’s home IP address.

Instead, you may only see the IP address of their mail servers. That means you might learn that the email came through Google. You probably will not learn where the sender was sitting.

This is good for privacy. It is bad for internet detectives who hoped to solve the mystery before lunch.

Watch out for fake headers

Email headers can be tricky. Some parts can be forged. Spammers love tricks. They may add fake Received lines to confuse people.

That is why you should trust the lines added by your own email provider more than random lines inside the message. If the email is serious, such as a threat or fraud attempt, do not play hero. Save the email. Report it to your email provider, your workplace security team, or local authorities.

Quick example

Imagine you get a strange email. You open the full header. Near the bottom, you see this:

Received: from unknown (HELO laptop) ([198.51.100.77])
by mail.example.net with ESMTPA;
Mon, 12 Jan 2026 09:15:22 +0000

You spot 198.51.100.77. You paste it into an IP lookup tool. It says the IP belongs to an internet provider in a certain region.

Nice clue. But still, it does not prove the sender’s exact location. They could be using a VPN. They could be on public Wi-Fi. They could be sending through a remote server. The internet loves disguises.

What if there is no useful IP address?

That happens a lot. If the sender used a major webmail service, you may not find a personal IP. If the message came from a newsletter platform, you may only see that platform’s servers.

In that case, look at other clues:

Those clues can be more useful than an IP address.

Final thoughts

Locating an IP address from an email is not magic. It is more like reading a travel log. Open the full header. Find the Received lines. Pick a public IP address. Then use an IP lookup tool.

Just keep your detective hat balanced. The result is usually a rough clue, not a perfect location. Use it to spot suspicious emails, understand routing, and stay safer online. And if something feels dangerous, report it instead of chasing it yourself.
