ASP.NET Core – How to Get the Client’s IP Address

asp.net-coreip-address

Previously in other version of asp.net, I used these properties of HttpRequest:

Request.ServerVariables["REMOTE_ADDR"]
Request.UserHostAddress

How can I achieve the same in ASP.NET Core?

You can use IHttpContextAccessor:

private IHttpContextAccessor _accessor;
public Foo(IHttpContextAccessor accessor)
{
    _accessor = accessor;
}

Now you get IP address this way"

var ip = _accessor.HttpContext.Connection.RemoteIpAddress.ToString();

The API has been updated. Not sure when it changed but according to Damien Edwards in late December, you can now do this:

var remoteIpAddress = request.HttpContext.Connection.RemoteIpAddress;
