The fun bit is that an auth server implementing some kind of proxying ANAME is in a position very like Google and OpenDNS. That is, if the target of the ANAME is a hostname provided by Akamai or CloudFlare or whoever, and if the auth server is going to proxy the answer faithfully, then it has to implement client-subnet.
