Retry DNS only after timeout

Open imsnif opened this issue 5 years ago • 5 comments

Right now, when we do our reverse-dns queries (getting the hostname of an ip address), if the request failed, we retry immediately. This can cause a lot of connections (also visible in the app!) to be opened if a request repeatedly fails.

It would be nice if we have some sort of progressive backoff mechanism for this... something like: wait for 1 second before retrying, then wait for 2, 4, etc.

Correct me if I'm wrong, currently we will retry every second?

Yep. I have a bit of a spotty internet connection though, so sometimes my whole connections pane is filled with our own DNS requests for minutes on end (which we somehow classify as unknown, btw). I thought this can make things a little friendlier.

Hi @imsnif I would like to work on it. Could you please give me start point?

@imsnif it looks like this was never completed and is quite old. Still relevant? Happy to pick it up
