如何在ASP.NET CORE中获取IPv4，IPv6，网络IP和访问者的MAC地址？

我已经使用下面的代码，但只获得:::1值。

var remoteIpAddress = Request.HttpContext.Connection.RemoteIpAddress; 

Answer 1

:::1是本地主机地址。你是对的。相反，你可以使用JavaScript代码。下面是代码为：

var myIP; 
    window.RTCPeerConnection = window.RTCPeerConnection || window.mozRTCPeerConnection || window.webkitRTCPeerConnection; //compatibility for firefox and chrome 
    var pc = new RTCPeerConnection({ iceServers: [] }), noop = function() { }; 
    pc.createDataChannel(""); //create a bogus data channel 
    pc.createOffer(pc.setLocalDescription.bind(pc), noop); // create offer and set local description 
    pc.onicecandidate = function (ice) { //listen for candidate events 
     if (!ice || !ice.candidate || !ice.candidate.candidate) return; 
     myIP = /([0-9]{1,3}(\.[0-9]{1,3}){3}|[a-f0-9]{1,4}(:[a-f0-9]{1,4}){7})/.exec(ice.candidate.candidate)[1]; 
     console.log('my IP: ', myIP); 
     $('#IpAddress').val(myIP); 
     pc.onicecandidate = noop; 
    };
