Compatibility with Cloudflare DNS

[etkaar]

Is nsupdate.info compatible with Cloudflare DNS without an abstraction layer?

[ThomasWaldmann]

If you want to use a DNS server with the nsupdate.info software or the instance of it at https://nsupdate.info/, then the DNS server needs to support "dynamic updates" (like e.g. bind9 and powerdns do).

If have no idea what Cloudflare uses or whether they support that, check their docs, ask them, or just try it.

And of course, not only the DNS sw needs to be capable of doing that, the dynamic update feature must also be enabled by its configuration.
