Is there a way to remove the server ip on the server banners? For example my minecraft server banner shows the actual ip. I would like to replace it with the mc.mywebsite.com

I am trying to avoide the little kids ddosing because the got the actual ip.

There is not currently a feature to replace the IP of the page on the image banners with the DNS of the page due to space constraints. If you use DNS on your server page, it will replace some of the locations where the server's IP is listed, but not all locations.

However, keep in mind that it only takes an extra 2 seconds to get the IP the DNS name points to. The fact of using a DNS address does not provide any sort of DDOS protection.
