Hi, hackers.
I have a question: why ipv4 netmask is displayed by ifconfig in hex format?
Isn't dot-decimal notation more human-readable? Will the attached patch
break something in the very bad way?
Who's using IPv4 anymore? ;-)
Seriously though, if you give a small amount of time to learning the
hex -> binary translations then you would see how convenient it is to
use hex rather than decimal when representing what are ultimately
binary numbers.
