In the definition of RRset, the bit about TTLs needing to be the same seems out of place for this terminology document. That is an operational requirement. Disagree. To some people, TTLs are operational, to others they are part of the master file format. For the latter, this sameness applies to the definition.
No, the zone file can contain different TTLs. As far as I know most implementations choose to reduce the TTLs for all RRs in an RRSet to the lowest value.
What I am saying is that whether the TTLs are the same (correct) or the TTLs are different (incorrect), it doesn't change the definition of RRset, which is the set of RRs with the same name/class/type. Therefore the requirement that the TTL be the same is not a useful statement for the definitions doc, whether it's operational or standards-based.
I agree. John _______________________________________________ DNSOP mailing list [email protected] https://www.ietf.org/mailman/listinfo/dnsop
