Map IPs to HOSTs & HTTPWebRequest

[orlandina]

I am absolutely new to the Network Programming...

Can anyone help me with the following?

I need to dynamically map and IP to a specific host name, and then execute the HttpWebRequest to that host name. Can you suggest how to do that?

The scenario:

I have a list of IPs and I need to map them to "some.web.com," by taking each of the IPs maping it to the host name and checking whether the connection exists, if it exists - do a webrequest....

Thanks in advance.



sample code:

I am trying to create the host entry:
(using internal IPs)

System.Net.IPHostEntry he = new IPHostEntry();
he.HostName = "some.web.com";


System.Net.IPAddress[] ipaddrs = {
System.Net.IPAddress.Parse("192.168.10.40"),
System.Net.IPAddress.Parse("192.168.10.50"),
System.Net.IPAddress.Parse("192.168.10.55"),
System.Net.IPAddress.Parse("192.168.10.60"),
System.Net.IPAddress.Parse("192.168.10.65")
};
he.AddressList = ipaddrs;

Then I need to connect to a site (but I want the connection to use one of the IPs above not the public IP)

HttpWebRequest wr = (HttpWebRequest)WebRequest.Create("http;//some.web.com/folder/file.html");
HttpWebResponse wresponse = (HttpWebResponse) wr.GetResponse();


PLEASE HELP!!!
