Hi Folks,
I have a question if I run "dig NS EMBLEY.COM @a.gtld-servers.com", I receive:

;; AUTHORITY SECTION:
EMBLEY.COM. 172800 IN NS rick.ns.cloudflare.COM.
EMBLEY.COM. 172800 IN NS rose.ns.cloudflare.COM.
;; ADDITIONAL SECTION:
rick.ns.cloudflare.COM. 172800 IN A 173.245.59.139
rick.ns.cloudflare.COM. 172800 IN AAAA 2606:4700:58::adf5:3b8b
rose.ns.cloudflare.COM. 172800 IN A 173.245.58.141
rose.ns.cloudflare.COM. 172800 IN AAAA 2606:4700:50::adf5:3a8d

Rose and Rick are not in-bailiwick records required for the resolution
of cloudflare.com (that use ns3-ns7.cloudflare.com as authoritative
NS).

So, why these records are in the .com authoritative server? Is it
optimization for Cloudflare?

Thanks,
Raffaele
