Barry Margolin pointed out an amusing interaction between two stupid DNS tricks on the bind-users list: https://lists.isc.org/pipermail/bind-users/2014-May/093171.html
If you have an authoritative server with "ANAME" or "CNAME flattening" support, and the target of the ANAME is a CDN that does source-based answer selection, then the synthetic A / AAAA records will be based on the auth server address rather than the client address, unless you have some special arrangement between the auth server and the CDN like edns-client-subnet support.

Good, occasionally poor. _______________________________________________ DNSOP mailing list DNSOP@ietf.org https://www.ietf.org/mailman/listinfo/dnsop
