It may be legit on your network, but people generally don't do that.... If they publish a aaaa record, it usually has a legit v6 address in it. That said, what they have done breaks in dns64 networks. This could be a real downer for them in the near future if they dont remove this aaaa. I am sending this mail in attempt to head of impending disruptions for www.rt.com for some subset of users. And www.rt.com is one of only two sites in the alexa top 25,000 websites to do this thing. http://www.employees.org/~dwing/aaaa-stats/ipv6-map.2016-07-07_0800.txt So, again, it would be great if www.rt.com could remove the aaaa.
