Hi all,
My server is a caching-only server, and provides recursive service with
"minimal-response YES". when i digged some domain name, my server answered
with all fields « ADDITIONAL RECORDS » and « AUTHORITATIVE NAMESERVERS »
fill with the DNS root server. I think this is WRONG and useless.
/
Just like as following:
% dig @127.0.0.1 plaid.princeton.edu. A
; <<>> DiG 9.11.2 <<>> @127.0.0.1 plaid.princeton.edu. A
; (1 server found)
