How to clear DNS cache in OS X 10.10.5?

How to clear DNS cache in OS X Yosemite 10.10.5? I am wondering what is the command to clear the DNS cache using terminal?

Note: I have never tested this.

In Terminal.app, type

sudo killall -HUP mDNSResponder

You may also download CleanMyMac. It provides a nice interface for flushing DNS cache.
