Hello dnsop,

here is a quiz for experienced RFC archeologists:

https://tools.ietf.org/html/rfc1035#section-5.2
section 5.2. Use of master files to define zones
does not mention NS at apex at all, but it does explicitly mention SOA
at apex. Can it be interpreted as if NS at apex is not mandatory?

Funnily enough
https://tools.ietf.org/html/rfc1035#section-5.3
has an example which as NS at apex, but it is not clear from the text above.

Is it mandatory or not? Should I submit erratum for RFC 1035?

Thank you for clarification.
