Speaking as myself, CF is wrong here. They need to have the zone active before changing the registrar details. Otherwise, the first requests between changing the NS and adding it to the servers will be incorrectly handled. This is pretty normal with forward-zones as well. -peter On 2025 Jan 30 (Thu) at 13:35:17 +0200 (+0200), Hank Nussbacher wrote: :We have a customer with an inverse object (in-addr.arpa) whereby the 3 :nameservers listed are long extinct and need to be replaced. : :So the customer went to Cloudflare and paid to use their 2 nameservers :(specifically harley.ns.cloudflare.com :and teagan.ns.cloudflare.com). : : :Yet, when I go to RIPE to update their inverse record I get many standard :errors that the nameservers do not exist yet to serve this inverse domain. :The customer tried to create the zone in cloudflare, but CF asks them to :change the DNS in the RIPE object, but to change the RIPE object they need :first to have an active DNS zone…. : : :So what is one to do in such a case? : : :Thanks, : :Hank -- Mother is the invention of necessity.
