[Dnsmasq-discuss] dhcp-lease-max is only for DHCPv4?

Other thoughts (maybe dumb, but could be easily overlooked):
  - An easy-ish thing to check in the source: is the counter wide enough
    (16-, 32- or 64-bits)?
  - What happens when max is set to 4, 16, etc.?
    o Is there a maximum before the limit fails to limit?
    o Does it always assign max+1 leases?
  - Do each of the clients have different MAC addresses?
The answers could yield a clue.
