Let me see if I got you correctly here, you want to point your domain to your radio server, probably not the main site, probably a subdomain like
http://radio.yourdomain.tld/ ?
Here's what you do...
If your streaming server has a static ip
set up an A record in your dns settings *you might not have access to these, but look at the third option if you don't as that may still work for you* pointing to your radio servers ip address as RADIO.YOURDOMAIN.TLD. ( don't forget the trailing dot, unless you use a service like godaddy that does the entrys for you ) to do it correctly just copy your first a record, change the IP and add the subdomain to the beginning of it. * a cname won't work in this instance because cnames can't point to IP addresses *
If your IP is dynamic, go to dyndns.org and set up a free dynamic domain. Next add a CNAME into your dns records that points to the dynamic domain.
If you do not have access to your dns records, you may have a feature known is subdomain forwarding via your ISP. This works like a CNAME, in fact, in some cases it may even be done via a CNAME ( which is better ), however some servers do it via a .htaccess file... lets not worry too much about that just yet. Anyway, like in option two, this method will require a dyndns domain name for the server, and then just set up the subdomain redirect to the dyndns domain.
Your final option, which does not require any modification of dns records, if your on an apache server ( IIS supports this as well, but the method is unknown to me as I've never used it ). If your IP is static, you do not need a dyndns domain, if it is dynamic, you will need a dyndns domain ( or similar dynamic domain name service ) You will need to have modrewrite enabled on your server, and you basically use an .htaccess file to rewrite the url request information to point to your radio servers IP or dyndns domain. First create the subdomain, then in the root of the subdomains folder put a file named .htaccess with the following code --
rewriteEngine on
rewriteBase /
rewriteCond %{HTTP_HOST} ^radio.yourdomain.tld$
rewriteRule ^(.*) http://dyndnsdomain.or.computerip/$1 [L,R=301]
and blam, as long as mod_rewrite is enabled on the apache server, It should work.
Now your final last resort option is to talk to your domain/webserver ISP and get their support to do all the dirty work for you ( except the dyndns domain if you have a dynamic IP, you'll need to set that up on your own regardless )
Hope that's what you wanted and good luck.
