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 Peter van Dijk <peter.van.d...@powerdns.com>于2017年4月13日周四 上午3:10写道： > On 11 Apr 2017, at 20:16, Paul Wouters wrote: > > > On Tue, 11 Apr 2017, Tony Finch wrote: > > > >> ANAME > >> records are not just for zone apexes.
