Re: [Cbor] Multiple questions with CBOR for DNS

[Carsten Bormann <[e-mail]>]

Well, if 65 % of all queries (number picked out of thin air) are single-question and AAAA, we are adding at least 0.65 bytes to the average question.
Exercise to the reader: How many tons of CO2 is that per year?

(I’m not saying we need to spring for every opportunity to save 0.65 bytes, but this one seems too easy to leave it.)

Grüße, Carsten

Currently, it defaults to 28 (AAAA records), so if we make the type necessary it should be the according record type number. But that exactly should make clear, that we are not just adding a single byte but up to three, as the number space of record types is 1 to 65535.
