Hello,
Please see this case:

When a resolver query funnygamesite.com from one of the gtld name
servers, will the resolver use the reference (AUTHORITY SECTION and
ADDITIONAL SECTION) directly? or it make another query for
ns1.dnsbed.com and ns2.dnsbed.com and get the authorative answers for them?
Thanks.
