How to Get the Client IP Address in ASP.NET Core?

Retrieving the Client IP Address in ASP.NET Core

Original Problem:

The traditional method, Request.ServerVariables["REMOTE_ADDR"], for obtaining the client IP address in ASP.NET Core MVC 6 is now obsolete.

Updated Solution:

Due to recent API updates in ASP.NET Core, a new approach is necessary to retrieve the client's IP address. As noted by Damien Edwards, the following code provides the correct solution:

<code class="language-csharp">var remoteIpAddress = request.HttpContext.Connection.RemoteIpAddress;</code>

This revised method utilizes the Connection property within the HTTP context to successfully retrieve the remote IP address, effectively replacing the outdated Request.ServerVariables["REMOTE_ADDR"] method.
