MCPlay.pw
This is something I created almost a year ago, and a year later it is still frequently being used by multiple servers. Also I noticed that I never created a topic here, so here it is.
What does it do?
This 'thing' will change your numerical ip (e.g. 174.38.12.210:25567) to a ip without a port (e.g. myminecraft.mcplay.pw)
What does it cost?
Nothing! DNS is done by Cloudflare so it doesn't cost me anything.
It's up for quite some time
