Does cloudflare support `nsupdate` aka `RFC 2136`

Hello, wonderful people! While going through the ddclient documentation, I came across the nsupdate protocol. Since I’ve recently moved my domain management to Cloudflare, I was curious whether Cloudflare’s DNS servers support the RFC 2136 DNS Update protocol. Additionally, if it's supported, could anyone guide me on how to obtain a "TSIG" key through the Cloudflare DNS dashboard? Thanks in advance!

Hello, can't answer that for sure but using an CF API key (token/passord) with ddclient for regular DNS updates works just fine in my experience, cheers! Curious however so like to follow up :p

Did you use dyndns v2?

No plain cloudflare protocol, so not sure, i'll share a working config ipv4 only for example.com:

daemon=600
syslog=yes
pid=/var/run/ddclient/ddclient.pid

use=web, web=checkip.dyndns.org/, web-skip='Current IP Address:'

protocol=cloudflare,
zone=example.com,
ttl=1,
login=token,
password=API_KEY
example.com,www.example.com

daemon=600
syslog=yes
pid=/var/run/ddclient/ddclient.pid

use=web, web=checkip.dyndns.org/, web-skip='Current IP Address:'

protocol=cloudflare,
zone=example.com,
ttl=1,
login=token,
password=API_KEY
example.com,www.example.com

The problem really is that I want something not bound to a vendor

I understand 😉

Anyway, I'll read some RFCs and see what happens. Thank you for your help
