Dear Sir,
When I am query through dig for nkn.in domain without any additional parameter, It is showing 3 ADDITIONAL records. And when I am query through dig for same nkn.in domain with +dnssec parameter, It is showing 4 ADDITIONAL records but there are only 3 answers in ;;ADDITIONAL SECTION. Why is it so???????
