I want to know if I can setup custom/private name servers on cloudflare, and then have other domains use those name servers too.
For example I currently have NS1 & NS2 records pointed at a name server I’m using outside of cloudflare, and I have several web design clients using those name servers too setup in their registrars.
So, if I setup my name servers on cloudflare can I also add my clients dns records for their domains too?
(I’m picturing adding a new site, and instead of having the options of only greg and fiona my name servers would be an option too)
Depends on what you mean by “set up”. You can simply create X A(AAA) records, point them to an (unproxied) IP address where your own nameserver is running, and use these records for the other domains. You cannot use the Cloudflare nameservers however.
