var iplist = Dns.GetHostEntry(Dns.GetHostName()).AddressList.Where(ip => ip.AddressFamily == AddressFamily.InterNetwork).ToList();
foreach (var ip in iplist)
{
     listBox1.Items.Add(ip.ToString());
}

string localIP = Dns.GetHostEntry(Dns.GetHostName()).AddressList
            .FirstOrDefault(ip => ip.AddressFamily == AddressFamily.InterNetwork && ip.ToString().StartsWith("10"))?.ToString();
string computerName = Environment.MachineName;
