You can use one or multiple custom domain names for your UniFi server to fully white label your service. Here is how:
Ping your HostiFi server name to get the IP address
Create an A record at your DNS provider with your custom domain name or names, and point them to the IP address of your HostiFi server
Send an email to support@hostifi.com or live chat us to let us know you are ready for the SSL to be installed for the new name, if using multiple names include all of the names each time you request a new certificate
We will install the SSL and follow up with you shortly
