Answer 1

This has changed since the publication of the original answer. Access it through

 httpContext.Features.Get<IHttpConnectionFeature>()?.RemoteIpAddress 

Answer 2

If you have access to the HttpContext , you can get the local / remote IpAddress from the Connection property as follows:

 var remote = this.HttpContext.Connection.RemoteIpAddress; var local = this.HttpContext.Connection.LocalIpAddress; 

Answer 3

HttpRequest.UserHostAddress gives the IP address of the remote client. In ASP.NET Core 1.0, you need to use the HTTP connection function to get the same thing. HttpContext has a GetFeature<T> method that can be used to get a specific function. For example, if you want to get the remote IP address from the controller action method, you can do something like this.

 var connectionFeature = Context .GetFeature<Microsoft.AspNet.HttpFeature.IHttpConnectionFeature>(); if (connectionFeature != null) { string ip = connectionFeature.RemoteIpAddress.ToString(); } 

Answer 4

For aspnet rc1-update1, I found the IP (with port) in the X-Forwarded-For header, which can be accessed from the controller as HttpContext.Request.Headers["X-Forwarded-For"].FirstOrDefault() .
