I recently set up Minecraft server (with port forwarding) and I was using a No-IP domain for it (foo.sytes.net.) I purchased a domain for the server, so I didn't have use a No-IP subdomain (minecraftserver.com). I purchased the domain through GoDaddy.
I've attempted to set a subdomain for my site (play.minecraftserver.com) to forward to my No-IP site, but discovered this doesn't work. No-IP is a great service as it can check if your IP address changes, but GoDaddy can't do this, otherwise I would have simply set the subdomain to my IP and Minecraft port.
Is there a way to give myself a static IP address or use No-IP with GoDaddy so I can use a subdomain with my Minecraft server?
