Clearing your DNS cache in OS X

Leave a comment

I have to remember this one enough, it’s worth recording here for posterity. To flush the DNS cache in Mac OS X 10.5 and 10.6, run this command in Terminal: 

sudo dscacheutil -flushcache 

To do the same in 10.7 and 10.8, run this command: 

sudo killall -HUP mDNSResponder
