Hello,
RFC 2870 (Root Name Server Operational Requirements) say
2.7 Root servers SHOULD NOT answer AXFR, or other zone transfer,
queries from clients other than other root servers.
The update, RFC 7720 (DNS Root Name Service Protocol and Deployment
Requirements)
don't even mention AXFR at all.
All I found is https://tools.ietf.org/html/rfc7720#section-2
o MUST implement core DNS [RFC1035] and clarifications to the DNS
[RFC2181].
Is AXFR a strict requirement for root-servers today?
Andreas
