Finding out if my sub-domain is re-directing...

I have a sub-domain that is supposed to re-direct users to an activation server for my software.  It stopped functioning when Blue Host changed their interface.  I have contacted them about setting the re-direct back up and they are supposed to have setup again about 36 hours ago.  However, things are still not working.  How can I "ping" the subdomain to find out what IP address it is resolving to?  As of now, I get the standard "Page cannot be displayed" message where I should get the ASP dump from the page....Any ideas or suggestions would be welcome...Thanks.

On a command-line:
ping subdomain.mydomain.com

Firefox has an extension called Live HTTP Headers that you might find useful.  You visit a URL with Live HTTP Headers open, and it shows you all the headers that get sent back and forth, including redirects.

You can do it via telnet as well.

Try this:

telnet.exe <host> 80  (assuming port 80)

When it connects, you need to paste this text into telnet:
GET /index.html HTTP/1.1    (change page as needed)
host: <host from above>
hostname: <host from above> 
<cr>
<cr>

(Can never remember if you need host: or hostname: -- adding both won't hurt)

Two blank lines above are important. 

You'll get back the raw HTTP response and see if there is a redirect there or not.

Better yet, go to http://web-sniffer.net/
Type in your domain (with subdomain you want to test).

If you expect a redirect, it should be a 3xx status code based on the type of redirect (look up HTTP status codes).

The web site shows the entire response.
