[discussion] "Greasing" EDNS options (random extensions against ossification) #84

Open pspacek opened 5 years ago

pspacek commented 5 years ago

Specification: DNS variant of https://datatracker.ietf.org/doc/draft-ietf-tls-grease/

Expected advantage: Enforcing interoperability for not-yet-invented EDNS options. Prevents ossification of EDNS extension mechanism.

Expected disadvantage: A bit surprising EDNS options in queries and packet captures.

Expected implementation complexity for software developers: Small

Expected non-compliance: Very small, DNS flag day 2019 already cleaned vast majority of breakage.

Research to confirm assumptions: TBD
