Random Notes
------------
 
* Can go from IPAddr integer representation back to human-readable IP format using NetAddr:
 
  irb(main):091:0> ip=IPAddr.new("208.79.88.0/24")
  => #<IPAddr: IPv4:208.79.88.0/255.255.255.0>
  irb(main):092:0> ip.to_i
  => 3494860800
  irb(main):093:0> NetAddr.i_to_ip(_)
  => "208.79.88.0"
 
* There is also a NetAddr.ip_to_i(), so using IPAddr is unnecessary
 
* Look into NetAddr::CIDR#subnet
