Also note it is PLURAL - and not all of them may work at a given time.

True, but i think it rare case that this method returns more then one address, especially in case of internet domains.

Andrey 2010-03-17 12:37:36

Andrey: Try `Dns.GetHostAddresses("google.com");`.

@Brian - six IPs! WOW! so you need to store them all and pick next if one doesn't work.

+2 A:

You could use the GetHostAddresses method:

var address = Dns.GetHostAddresses("www.test.com")[0];

Will this work in vb.net?

Moshe 2010-03-17 12:37:45

no good. what if result set is 0? or more probably more than 1?

Andrey 2010-03-17 12:38:50

@Moshe, of course, it is from BCL

Andrey 2010-03-17 12:39:17

@Moshe: It should if you have access to the `System.Net.Dns` class.

@Andrey: If more than one, it would just ignore the rest. If 0, I guess it would crash :p

Svish 2010-03-17 12:39:59

@Moshe, in VB.NET : `Dim address = Dns.GetHostAddresses("www.test.com")(0)`

Darin Dimitrov 2010-03-17 12:40:28

@Andrey, @Svish - Silly me, but of course. @Darin Dimitrov - Thanks.
