Get All IP Addresses on Machine

Question

How can I get all of the IP addresses attached to the machine that my application (C# NET Console app) is running on? I need to bind a WCF service to the primary IP address,

Answer 1

I think this example should help you.

// Get host name
String strHostName = Dns.GetHostName();

// Find host by name
IPHostEntry iphostentry = Dns.GetHostByName(strHostName);

// Enumerate IP addresses
foreach(IPAddress ipaddress in iphostentry.AddressList)
{
    ....
}

Edit:

"There's no such thing as a "primary" IP address.

The routing table determines which outward-facing IP address is used depending on the destination IP address (and by extension, the network interface, which itself can be virtual or physical)."
