SeeIP is a simple IP address API that returns the Internet address of the calling server.
You can use it without any real limit.
It's open source, and 100% free to use.
It will always be online and secure.
No user information is ever logged no matter what. We value privacy.
SeeIP is funded by Alpha Geek Solutions, LLC, you don't need to worry about the website disappearing or the SSL certs expiring, which we've had some trouble with in the past and is one of the main reasons why we wanted to fund and serve an open public IP API ourselves.
Please note that the IP location database, which for this API is Maxmind, may not contain all information about a given IP. In this case, only the available data is displayed.
