[Bug 1497450] [NEW] DNS lookup code in get_ports needs to be optimized

 

Public bug reported:

Kilo's get_ports code can be found at http://pastebin.com/PjVG2KFt while
Liberty's get_ports code can be found at http://pastebin.com/wpmTx8H7

The difference in the two code paths (the DNS code) leads to an
execution time difference shown in http://ibin.co/2G72PkX2eshD
