Description

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.

Contributor guide

Research direction
Examine the current DNS retry logic in the reverse dns implementation and propose a progressive backoff strategy (e.g., exponential backoff with jitter).
