dig failed to recover from BADVERS
The ednscompliance:DiG's EDNS negotiation
test failed on main
.
It seems that dig +norec +edns=100 soa .
failed to recover from BADVERS
as the dig
output only has:
;; BADVERS, retrying with EDNS version 0.
But it failed to get the answer after retry with +edns=0
, e.g.:
;; BADVERS, retrying with EDNS version 0.
; <<>> DiG 9.19.2-dev <<>> +norec -p 5300 @10.53.0.1 +edns soa .
