Thank you! I've changed that.

Yes, quite a lot of random traffic seems to be captured, some of it
identifiable as coming from other devices on my network (e.g. a
macbook is mentioned, and I think mdns is "Bonjour" traffic?).
10.0.0.1 is my router obviously.
Here's several seconds of traffic captured with "tcpdump -l -i iwm0 |
tee output" during which I gave the command "dhcpleasectl iwm0" with
the output "iwm0 [Init]" and no ip address assigned.
