I'm about to add Nameservers into Helm, but I don't know where I get these from? How do I know what they are, and what the IPs of them are?
A name server is a program that translates names from one form into another. For example, the Internet relies on Domain Name Servers (DNS) that translate domain names into IP adresses.
You need to create your own nameservers for use with hosting your domains.
These are set-up on a domain of your choosing, with your registrar. You should refer to your service provider / registrar on how to do this. Once the service provider / registrar has given you the nameserver details, you can add them into Helm.
