Usage

require "ip_address"

Some samples:

address0 = IP["127.0.0.128"]
address1 = IP["10.0.0.0"]?
address2 = IP.new("127.0.0.0")
address3 = IP.new?("127.0.0.0")

address4 = IP["2001:0db8:123:4567:89ab:cdef:1234:5678"]
address5 = IP::Address["1::2"]?
address6 = IP.new("::1")
address7 = IP::Address.new?("::0")

block0 = IP["127.0.0.0/8"]
block1 = IP::Block["10.0.0.0/8"]?
block2 = IP.new("127.0.0.0/8")
block3 = IP::Block.new?("127.0.0.0/8")

block0 = IP["127.0.0.0/8"]
block1 = IP::Block["10.0.0.0/8"]?
block2 = IP.new("127.0.0.0/8")
block3 = IP::Block.new?("127.0.0.0/8")

loopback = IP::Address::IPv4.loopback

block0.includes?(address0)
