Thank you for the detailed explanation.

> The meaning of this message is described in the FAQ.

> ntop does address resolution asynchronously, and there is a queue of items
> remaining to be resolved.  On a busy network, there can be a lot, especially
> @ startup.  But once things settle down, there rarely are many.  So we just
> put a limit on the queue.
>
> If ntop finds a packet from that unresolved host later on and the queue
> isn't full, it gets added and resolved then.  So typically, after a few
> minutes things settle down.
>
> If this happens during a run, it can be a sign that ntop can't access the
> dns server.  If your DNS server has changed, the only way I know to change
> where ntop is looking is via a restart.  However, remember that ntop also
> sniffs DNS packets that other hosts send/receive - as a way of avoiding the
> overhead of our own DNS queries.

> Either way, you can ignore it - it just won't show you all of the
> translations from IP addresses to names.
