Hello,

If we see this on our DNS server logs (BIND 9.11):

04-May-2022 12:55:37.675 edns-disabled: info: success resolving 
'sour.woinsta.com/A' (in 'woinsta.com'?) after disabling EDNS

- are we correct to say that with BIND 9.16, that query wil always fail because 
EDNS won't be disabled anymore ?
- is there any tuning that needs to be done ?
- with BIND 9.11: how many times does BIND try before disabling EDNS ? from 
what we can see in the logs, BIND seems to first try all NS and as they all 
fail, then it disable EDNS and then retries. Is it correct ?

Thanks,
Veronique
