Question

how to get ip address of machine in c#

Answer 1

First google result or another one

Answer 2

IPAddress[] localIPs = Dns.GetHostAddresses(Dns.GetHostName());

Your machine doesn't have a single IP address, and some of the returned addresses can be IPv6.

MSDN links:

• Dns.GetHostAddresses
• IPAddress

Alternatively, as MSalters mentioned, 127.0.0.1 / ::1 is the loopback address and will always refer to the local machine. For obvious reasons, however, it cannot be used to connect to the local machine from a remote machine.

Answer 3

This article shows everything.

Better if you can do a small research before asking a question.

Answer 4

 IPHostEntry ip = DNS.GetHostByName (strHostName);
 IPAddress [] IPaddr = ip.AddressList;

 for (int i = 0; i < IPaddr.Length; i++)
 {
  Console.WriteLine ("IP Address {0}: {1} ", i, IPaddr[i].ToString ());
 }

Answer 5

My desired answer was

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