Get specific IP address of PC, regardless of which adapter.

Anthony Gags

Hi There,

i have a program that is trying to get the IP address of any PC on our netowrk

I have been using the below semi-successfully, yet it will only work if an IP address actually exists in the first list.

string HostName = Dns.GetHostName();

Dns.GetHostEntry(HostName).AddressList[0].ToString()

however,

the problem arises when the entry 0 does not exist, and it is actually entry 1 or 2 for that matter..

How can i go around this so that no matter which entry actually has the IP address of 192.168.XXX.XXX, it will p[ick it up and tell me the whole IP.

Thanks in advance

Accepted answer
public static string GetLocalIPAddress()
{
var host = Dns.GetHostEntry(Dns.GetHostName());
foreach (var ip in host.AddressList)
{
if (ip.AddressFamily == AddressFamily.InterNetwork)
{
return ip.ToString();
}
}
throw new Exception("Local IP Address Not Found!");
}

Try this code,
string hostName = Dns.GetHostName(); // Retrive the Name of HOST
Console.WriteLine(hostName);
// Get the IP
string myIP = Dns.GetHostByName(hostName).AddressList[0].ToString();
Console.WriteLine("My IP Address is :"+myIP);
Console.ReadKey();
