How does it refresh DNS in Mac OS X?

IF Yosemite

sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.discoveryd.plist

sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.discoveryd.plist

IF Mavericks || Mountain Lion || Lion

sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.mDNSResponder.plist

sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.mDNSResponder.plist

IF Lower than Lion

sudo dscacheutil -flushcache

So if you meet the situation that your computer is something wrong with remote host resolving, please repeat the command(s) above!
