- tptacek 7y agoWe've been talking on HN about mDNSResponder for over 5 years. It has un-baked DNSSEC support that macOS has never used. mDNSResponder was replaced by another service (Yosemite's Discoveryd) which had zero support for DNSSEC, but instability forced them to revert back. The macOS system resolver does not support DNSSEC, has never supported DNSSEC, and the fact that mDNSResponder has/had DNSSEC code is not an indication that they're embracing it. By the way: I have better sources on this than just my opinion of the source code.
- alwillis 7y agoPay attention to the fact that applications can use the DNSSEC support in the networking framework if they wanted to. That was all.
