Dynamic-DNS allows anybody running their own Minetest server at home to have myworld.minetest.land for their server name, instead of 198.51.147.23, or minetest4.ds2.someisp.ex etc.
Web forwarding allows any Minetest project, player or website to take myproject.minetest.land as a URL.
minetest.land is registered for the next 10 years and pointed at FreeDNS ‐ at least until 2028!
FreeDNS provide apps so that any home computer can keep the chosen domain names automatically pointing to their home IP address.
