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

[Simon Kelley]

There's a possible difference between the number of clients and the 
number of DHCP leases, since leases can expire to be deleted by the client.

Are you saying that the number of simultaneous DHCP leases increases 
without bound, or that the 513th client gets a lease? Have you checked 
the number of leases in the dnsmasq.leases file?
