This hidden in the default output, but you can request it if you'd like:
❯ echo "google.com" | ./zdns A --name-servers=8.8.8.8 --result-verbosity=long | jq .

"data": {
"additionals": [
{

I noticed ZDNS does not provide header flags (QR, RD, RA, etc) that you would see if you ran dig.
dig A "google.com" @8.8.8.8

With ZDNS,
echo "google.com" | ./zdns A --name-servers=8.8.8.8
:{ "data": {"additionals":[{"flags":"","type":"EDNS0","udpsize":512,"version":0}], "answers":[{"answer":"142.251.214.142","class":"IN","name":"google.com","ttl":102,"type":"A"}], "protocol":"udp", "resolver":"8.8.8.8:53"}, "name":"google.com", "status":"NOERROR", "timestamp":"2024-02-17T22:33:07Z" }
I expected the ZDNS A module to be similar to dig, and it would be useful to have the flags. If there’s a way to get the flags that I’m not aware of, please let me know
