[DNSOP] DNS privacy and AS 112: the case of home.arpa

2017-12-11 Thread Stephane Bortzmeyer
During the discussions about draft-bortzmeyer-dname-root or about draft-wkumari-dnsop-internal, there have been many remarks about the risk for privacy if we delegate things to AS 112: unlike the root (or .arpa), AS 112 is managed by many different people we don't know and cannot know. So, leaked r

[DNSOP] Please review in terminology-bis: QNAME

2017-12-11 Thread Paul Hoffman
Greetings again. Some of the new terms added to the terminology-bis draft (https://datatracker.ietf.org/doc/draft-ietf-dnsop-terminology-bis/)since RFC 7719 can expose what some (but not all) people perceive as lack of clarity in RFC 1034/1035. This week, we hope you will look at the definiti
