I'm Migrating Windows Form Class Library to Metro App Class Library. In that there's a code-block which gives the IPAddress from the Host Name, below,

```
IPHostEntry ipHostInfo = Dns.GetHostEntry(Address);   
IPAddress ipAddress = ipHostInfo.AddressList[0];// IPAddress.Parse(address);
IPEndPoint endPoint = new IPEndPoint(ipAddress, Port);

```

eg:

Address : `talk.google.com`

ipAddress : `xx.xxx.xxx.xx` 

But I've seen that there is no `IPHostEntry` or `Dns` or `IPAddress` in Metro App System.Net. .

If anybody knows means please tell me the replacement for these in windows 8 metro app.
