If you want to setup your own domain to run on your own instance of gleams, you have two options. You can create a new A Record that points to 18.104.22.168 or change your NameServers to at least two of the NameServers listed below. You can make these changes at your domain registrar and the domain should start resolving to 22.214.171.124 within a few hours. It depends how long it can take, check periodically. It could take several hours to fully propagate. If you choose to switch your NameServers, please notify me and I will create a Domain Zone (will soon be automated) for your domain name. It is preferred that you just create an A Record to point here and manage your DNS elsewhere.
