Hi Peter,

one question, will authoritative server return multiple ANAME RRs for the
same domain at one dns query ?

for example,

www.example.com  ANAME  us.www.example.com
www.example.com  ANAME  cn.www.example.com

or  return only one selected ANAME RR for one domain ? (based on
authoritative's policy, resolver ip/client subnet/...)

www.example.com  ANAME  us.www.example.com

thanks
