Do your servers have a static IP?
Yes, all the accounts have static IPs.
A Static IP Address is simply a “permanent” address that remains associated with your audio streaming address. For example, a SHOUTcast typical streaming address is http://ipaddress:port, if you don’t have a static IP address your IP will change every now and then. You will have to correct the audio streaming address in your players and on the links you have on your website every now and then.
Also if the listeners have saved your streaming address to listen to your station and your streaming has not a Static IP, you will have to send them the new address so they can listen to.
Static IP is very convenient
