Hello Is it possible to send a DNS request packet with zero QDCOUNT using dig?
I'd like to test this behaviour from RFC 7873: For servers with DNS Cookies enabled, the QUERY opcode behavior is extended to support queries with an empty Question Section (a QDCOUNT of zero (0)), provided that an OPT record is present with a COOKIE option. Such servers will send a reply that has an empty Answer Section and has a COOKIE option containing the Client Cookie and a valid Server Cookie. Thank you, Egon Kocjan
