Here is some of the code in question:

IPAddress addr;
if (host == "*")
    addr = IPAddress.Any;
else if (IPAddress.TryParse(host, out addr) == false){
    try {
        IPHostEntry iphost = Dns.GetHostByName(host);
       if (iphost != null)
            addr = iphost.AddressList[0];
            addr = IPAddress.Any;
   } catch {
        addr = IPAddress.Any;
