How to get IPv4 of a HostName?

Question

I have a client in Windows 8 (RT) and I have an instance of HostName given by the user which can be either IPv4 or DomainName. Now for IPv4, it's OK but for DomainName it is not OK since it tries to connect using IPv6 and no app in the server is serving clients on IPv6 (just IPv4) so I am looking for a way to get the IPv4 of that DomainName and then try to connect.

EDIT: I want it in Windows 8 (RT) SDK not regular .net

What have you tried? Have you looked here, for example: http://stackoverflow.com/questions/6668810/c-sharp-get-ipv4-ipaddress-only — JleruOHeP, Dec 21 '12 at 16:06
Guys let me notice that I am asking it for Windows 8 RT sdk not regular .net cause then it was pretty obvious ! — Peyman, Dec 21 '12 at 23:02
Watch out, the term "Windows RT" is a minefield. See [meta](http://meta.stackexchange.com/q/152477/135887). — Charles, Dec 22 '12 at 01:18
@Peyman, my point being that the tag `windows-rt` should not yet exist, as there *it* is a minefield. — Charles, Dec 22 '12 at 01:24
@Peyman: have you got the solution for this?? If yes, let me know.. — , Dec 26 '12 at 09:10

string host = "www.stackoverflow.com";
System.Net.IPAddress ip = System.Net.Dns.GetHostAddresses(host)[0];

that's not available for WINDOWS 8 RT SDK. – Peyman Dec 21 '12 at 23:01
Note that in general this is not guaranteed to return an IPv4 - IPv6 can be returned. – w128 Jan 10 '14 at 15:29
