"DNS name has too many labels" error


#1

My domain is: a.e.f.f.0.b.8.0.1.0.0.2.ip6.arpa

It produced this output: Error requesting challenges: 400 b’{\n “type”: “urn:acme:error:malformed”,\n “detail”: “DNS name has too many labels”,\n “status”: 400\n}’

The maximum number of DNS labels is hard coded as 10, I need at least 14 for this to work.

That’s not a “domain” in the most commonly used sence, it’s the address for a PTR record, i.e., reverse DNS.

Why would you want a certificate for a reverse DNS? :hushed:


#3

It’s a hostname but the template for “Help” calls it a “domain” and I didn’t correct it.

Why shouldn’t I be able to get a certificate for any hostname that has A/AAAA records?


#4

Well, there are a number of arguments against a heck of a lot of subdomains, e.g., preventing DNS-spam.

Furthermore, I’m not sure why you would have A/AAAA-records for a reverse DNS? It’s very much not common.
