OS X 10.11 El Capitan - Flush DNS

On OS X 10.11 El Capitan, flushing DNS uses the same commands as 10.9 and previous. If you've seen the news, the last 10.10.4 betas showed that Apple has removed discoveryd and discoveryutil.


To flush your DNS on OS X 10.11, issue this command in terminal:

sudo dscacheutil -flushcache;sudo killall -HUP mDNSResponder;say flushed

    sudo dscacheutil -flushcache;

    ^ That's only for Snow Leopard, you can safely remove that part of the command.

    I can't get it to work. On my vps I rebound the IP in dns and restarted the service. I went to my off-provider alternate vps, flushed its cache (windows server) and pinged the new domain - it has the new ip. On OSX, using this command, ping still resolves to the old IP.
