#
# p ipaddr1.to_s #=> "3ffe:505:2::1"
#
# ipaddr2 = ipaddr1.mask(48) #=> #<IPAddr: IPv6:3ffe:0505:0002:0000:0000:0000:0000:0000/ffff:ffff:ffff:0000:0000:0000:0000:0000>
#
# p ipaddr2.to_s #=> "3ffe:505:2::"
#
# ipaddr3 = IPAddr.new "192.168.2.0/24"
#
# p ipaddr3 #=> #<IPAddr: IPv4:192.168.2.0/255.255.255.0>
