/31 prefix: hosts, network and broadcast

[PJO2]

Hello,

in the gem code, a /31 network has a network address, a broadcast address and has no host address.
For instance the 1.2.3.4/31 subnet will return 1.2.3.4 as network add, 1.2.3.5 as broadcast and each_host returns immediatly.

My understanding of the RFC 3021 about /31 prefixes is the contrary :
no network, no broadcast and 2 hosts available.

Tested with the following code:
require 'ipaddress' net=IPAddress "1.2.3.4/31" puts "network:", net.network puts "hosts:" net.each_host { |host| puts host } puts "broadcast:", net.broadcast
