The leftmost 0 means that the leases are infinite, they never expire,
which might explain why you're running out of leases.

There can be duplicate leases per MAC address, but there should never be
duplicate leases for an IP address. So I'm interested in finding out how
you've contrived this situation. Please could you share as much
information as possible about network and dnsmasq configuration?


Cheers,

Simon.
