A question for the reference

[Jeff Peng]

Hello,

Please see this case:

$ dig funnygamesite.com @k.gtld-servers.net

; <<>> DiG 9.7.3 <<>> funnygamesite.com @k.gtld-servers.net

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.
