Hi Authors, For section 5.3, I think 2 things should be explicitly stated. 1. hairpinning should be supported on the 4over6 concentrator 2. when 4-in-6 packets received, the inner ipv4 src ip address should be checked against outter ipv6 src ip to see if they are match. (Actually, this should be mentioned in security consideration section)
