People don’t want CNAME at the apex. They want a pointer to a server for a service at the apex. CNAME provided a pointer to a server when the prefix was www. This can be done a number of ways. 1) Prefix + name in rdata. 2) Service specific type + name in rdata. 3) Generic type + service and name in rdata. This is DNS choices from the IAB. ANAME is a extremely complicated version of 2 for HTTP which may be morphed into 1 with a well known service name for other services but will always have the risk of being misinterpreted. There are much simpler ways to achieve 2 than ANAME for HTTP. Mark -- Mark Andrews
