You’ll probably want to clear both for good measure if you’re trying to reset all DNS caches on the Mac.From OS X 10.10.4 moving onward to 10.10.5, including 10.11, Apple has ditched discoveryd and has replaced it (or rather, reverted back to) m DNSResponder.However, a common DNS caching application sometimes used is the Name Service Caching Daemon (nscd).It’s most likely not installed by default so there is no need to flush the cache.
