Discussion on: Daily Challenge #31 - Count IPv4 Addresses

[Philip Hallstrom]

Ruby, and totally cheating by using it's IPAddr class :)

def ips_between(from, to)
  IPAddr.new(to).to_i - IPAddr.new(from).to_i
end

[Massimo Artizzu]

This actually made me chuckle... lol cheating indeed 😁

[Andreas Jakof]

And it was my first idea as well... IPv4 Addresses are 4byte integers... so the easiest way is to subtract them. 😎
