Solution 1

C#

System.Net.IPHostEntry host = System.Net.Dns.GetHostEntry("COMPUTERNAME");
foreach (var ipAddress in host.AddressList)
{
    // Loop all ip-addresses. This object has a lot of properties v4/v6 etc..
    Console.WriteLine(ipAddress);
}

Hi,

see this link for some code:
http://www.dijksterhuis.org/converting-an-ip-address-to-a-hostname-and-back-with-c/[^]
I can use this code to look up the IP-Address of a server called "Panic":

C#

private void button1_Click(object sender, EventArgs e)
{
   IPHostEntry NameToIpAddress;
   NameToIpAddress = Dns.GetHostEntry("Panic");
   int AddressCount = 0;
   foreach (IPAddress Address in NameToIpAddress.AddressList)
      Console.WriteLine("IP Address {0}: {1}", ++AddressCount, Address.ToString());
}

Solution 3

C#

string strHostName="localhost";
IPHostEntry ipEntry = Dns.GetHostByName( strHostName );
IPAddress [] addr = ipEntry.AddressList;

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