      p ipaddr1                    #=> #<IPAddr: IPv6:3ffe:0505:0002:0000:0000:0000:0000:0001/ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff>

      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>
