How is this requirement different from other requirements ? If the document said 'provide ipv6 in this and such way' I'd understand your concern. But if the document just says 'root servers must answer queries over ipv6' I simply don't get your concern, or how this is 'telling folks how to operate their networks'. Every network design is a response to a set of requirements. Usually these set of requirements that answer a set of needs from a group of users. How is this different? Here the user group is the Internet as a whole. The Internet as a whole needs IPv6. As pointed out, other documents already exist that already say this. I could even argue that *the requirement already exists in the current BCP corpus*, I´m just saying here that it does no harm to make it explicit for root server operators. Now, how they solve it, that is operational, and that is the realm of each operators. Carlos
