Inspired by last week's conversation, I experimented with MAC
randomization on my laptop. And I DoS'd my own network by exhausting
its DHCP pool.

My very naive script reset the MAC after every network hiccup, so the
router kept seeing an entirely new device and giving it a new IP
address. Slowly. Until they were all gone. I "solved" my problem the
stupid way by rebooting the router and lowering the DHCP timeout from
24 to 3 hours.

A production script would be clever about resetting it only on new
associations, and not on every brief reassociation. However, still
something to keep in mind when deploying networks that encourage this
sort of thing. ;)
