hi!
Reset the DNS cache in OS X - Apple Support
lists:
OS X Yosemite
Use the following Terminal command to reset the DNS cache:
sudo discoveryutil mdnsflushcache
OS X Mavericks, Mountain Lion, and Lion
Use the following Terminal command to reset the DNS cache:
sudo killall -HUP mDNSResponder
Was there a change again, 10.10.4 (which should be Yosemite as well) returns an error for me (tried different macs), though the HUP on the
mDNSResponder process seem to work.
| system.log:Jul 9 18:35:33 mac.local sudo[54403]: | user: TTY=ttys010 ; PWD=/Users/user ; USER=root ; COMMAND=/usr/bin/killall -v -HUP mDNSResponder |
system.log:Jul 9 18:35:33 mek.local mDNSResponder[94]: SIGHUP: Purge cache
Maybe its time for Apple to update the documentation (left a comment there as well).
