Click on 'Admin' in your Shoutcast servers control panel.
You are then directed to your Shoutcast servers 'Status Page'. Next, click on the 'Server Login' link in the top right hand corner of the page.
Next the servers login box will appear. The username to login is 'admin' and the password is the same as your control panels 'Administrator' password.
Once logged in, across the top of the servers 'Status Page' is various administrator options. Click on the 'Ban List' option.
You can then ban a single IP or an entire subnet address from within this section. Just enter the IP address that you wish to ban or the subnet address of the entire subnetwork that you wish to ban.
*ICECAST USERS - Unfortunately with Icecast servers it is not possible to ban IP's yourself from within your 'Admin' page. However, we can block any IP's or a subnet for you ourselves. So please contact us here if you require this on your Icecast account.
