I set up a full node running Nelson, everything fine. I rented a Server together with a .de domain.
Atm I use my IP as adress of my node. Technical it works fine. But how can I change it to the domain I bought?
DNS if you don't want to pay for managed dns you can set it up locally on your server. if you're using linux with something like bind9 (https://www.vultr.com/docs/setup-your-own-dns-server-on-debian-ubuntu)
it's also worth noting to check your domain registrar because some of them have free DNS services
