How to Detect a Fake IP Number

Updated April 17, 2017

If you own a website and are the administrator of your own forum or message board, or if you run a blog where people can leave comments, you will have access to your members' IP addresses. An IP address is a number assigned to Internet users by their Internet service provider (ISP). These numbers change frequently and are different than other IP numbers, depending on a person's location. Sometimes, you will run into a problem with odd messages being posted on your message board or forum. If this happens, you will probably have suspicions and want to check whether the member's IP address is fake. There is a way to do this that is easy and reliable.

Locate the IP address or addresses you want to check. Copy and paste the number to Notepad or Wordpad on your computer so you don't lose it and have quick and easy access to it.

Navigate to an IP tracing website. An Internet search will bring up many options, or you can go directly to

Delete your IP address from the fill-in field. Enter the IP address you want to check in its place. Click the button that reads "Track IP, host or website."

Look over the information that comes up. It will show the city, state and country where the IP address originates from, as well as the Internet service provider and the host of the IP. If this information is missing, or you get a message that says it cannot be traced, the IP address is most likely a fake.


Often, when you cannot trace an IP address, it is a fake IP only meant to post spam advertisements.


Any time you track a fake IP meant to spread spam on your website, forum or blog, you should ban it in your domain's cpanel, or contact your site administrator to do it for you if you don't have access to do so yourself.
