C# asp.net Get Ipv4 ip address of a client [duplicate]

Question

My below code is getting ivp6 ip address am not sure how to get ipv4 in the same manner.

 string ipAddress = "";
           if (Dns.GetHostAddresses(Dns.GetHostName()).Length > 0)
           {
               ipAddress = Dns.GetHostAddresses(Dns.GetHostName())[0].ToString();
           }

string strHostName = System.Net.Dns.GetHostName(); IPHostEntry ipEntry = System.Net.Dns.GetHostEntry(strHostName); IPAddress[] addr = ipEntry.AddressList; In IPAddress array you can will get both the IP'S IPV4 and IPV6 — Ravi Kanth

This code: Dns.GetHostAddresses(Dns.GetHostName())

Will return an array of all IP addresses assigned to the local machine. When you assign to the ipAddress variable, you are using "[0]", which only takes the first IP address in the list.

Look at the entire array and you might find that you are indeed getting the IPv4 addresses too.

Take at look at the example in the documentation for GetHostAddresses. It shows how to loop through the results.
