Previously we were replying with A response for AAAA queries which was causing an error in some clients e.g nginx. The new approach waits for 1 second and then replies with NODATA. This approach allows for more semantic reply even when client uses same Transaction ID for both A and AAAA questions. Signed-off-by: Nino Kodabande <[email protected]>

There was a problem hiding this comment.
The change looks ok to me, and should fix the situation from rancher-sandbox/rancher-desktop#3447 (comment).
I'm slightly worried about the arbitrary delay of 1 second (why not 0.5 or 2 seconds?), but I think it should work fine as long as the machine isn't already overloaded.
@AkihiroSuda please merge, if you have no objections!
