[DNSOP] Caching of negative zone (non-authoritative) responses

2019-07-08 Thread Michael J. Sheldon

Section 1: Current issues #1 says "use TXT or new RR? (ATB: new RR, but TXT for now)" Is there a single person here who believes this? Once implemented as TXT, I give the odds of seeing a specific type record being implemented as less than zero. Pick one, don't tease. Section 2: I am
