请参阅我对该问题的评论。



如果您有一些URI并想知道IP地址，则没有一对一的通信，因为任何主机都可以提供多个IP地址。这与ASP.NET或HTTP无关，是DNS的责任。



例如：

Please see my comment to the question.

If you have some URI and want to know IP address, there is no one-to-one correspondence, as any host can serve multiple IP addresses. This is not related to ASP.NET or HTTP and is the responsibility of DNS.

For example:

System.Net.IPAddress[] addresses = System.Net.Dns.GetHostAddresses("www.CodeProject.com");

注意，这是一个IP地址数组，而不仅仅是一个。



如果你需要获得一个IP地址客户端，更确切地说，是HTTP请求（不是响应，因为你总是在服务器端知道并且它实际上没有使用它），你可以使用 HttpRequest.ServerVariables [REMOTE_ADDR];

Note, this is an array of IP addresses, not just one.

If you need to get an IP address of the client, more exactly, of the HTTP request (not response, as you always know it on the server side and it is not actually used), you can use HttpRequest.ServerVariables["REMOTE_ADDR"];
