  Nothing would get done in the world, if we didn't have insomniacs.
           Or at least, nothing would get done at night.

>Description:
Option parsing for arp is dependent on order of the options: arp -na only
shows numeric ip-adresses, arp -an does hostname-lookups (wich it shouldn't).
>How-To-Repeat:
arp -na; arp -an and observe the difference.
>Fix:
first check for the n option, then parse the other options.
