Could you please be more specific? When you say "for the specific service", do you mean DNSSEC? And do you mean the signing of DNS zones using DNSSEC, when you refer to clients of that service? Perhaps you missed my microphone comments at the last IETF? Specifically that GoDaddy will be turning on DNSSEC for the vast majority of its DNS hosting customers? This represents about 40% of the DNS zones on the Internet. (The exact time frame is not set in stone, but we expect this to be done in the first half of 2020.) Given that this significantly alters the calculus, I don't think that is a good enough reason to object in and of itself anymore. The other aspect of this is the asymmetry involved in the defenses against impersonation: - The choice to sign a DNS zone is under control of the zone owner - The choice to deploy RPKI on routes (to protect against BGP hijacking) is under control of the IP prefix holder - Both methods rely on third parties to cooperate to achieve the protections offered - RPKI routing filters are now widely deployed, and RPKI registrations are substantial - The remaining issue is DNSSEC validation; many (most?) of the public recursive operators do this already The logic should be, defend against all feasible attacks, rather than justifying the non-defense in one area (DNSSEC for DNS) based on the assertion that another area is not being defended (RPKI for BGP).
