Hi,

How can I get the IP address of a network card in my machine? I have the
NetworkInterface object corresponding to that card

Thanks!

Some old code from the shelf:

using System;
using System.Net.NetworkInformation;

namespace EE
{
public class MainClass
{
public static void Main(string[] args)
{
NetworkInterface[] nics =
NetworkInterface.GetAllNetworkInterfaces();
foreach(NetworkInterface nic in nics)
{
if(nic.GetPhysicalAddress().ToString().Length > 0 &&
nic.GetIPProperties().UnicastAddresses.Count > 0)
{
Console.WriteLine(nic.GetPhysicalAddress() + " " +
nic.GetIPProperties().UnicastAddresses[0].Address);
}
}
}
}
}

Hi,
Let me explain you what is IP address and MAC adress. IP address is a
logical address which is in 32 bit given by either manuallyor by the system
administrator or through DHCP dynamically. MAC address is a physical address
which is in 48 bits. It is given by the manufacturer and that can not be
changed and it is in permanent in nature.

When assign a IP Address this address will map to the MAC address, Now the
logic is that as you are knowing MAC just you have to pick up IP.

See in case of Virtual LAN one NIC may ge assigned with more than one IP.
Then whic IP is active that IP Address you will get.

My guess is that everybody here knows, so why explain it
when nobody asked.
