I have an isc-dhcp-server running in a Docker container, which I configured with one subnet of 100 available IP @.
When starting my laptops (they are all running Linux OS), when they are requesting IP@, they are all offered with the same one by the DHCP server, even though they have different MAC@.
When I have a look at the /var/lib/dhcp/dhcpd.leases file, I see different "lease" lines, one per laptop, but with the same IP@.
Is there a specific configuration to make sure that the DHCP server assigns different IP@ or do you see what could be wrong here?
