Hi, thank you for your quick respond. You are absolutely right, I missed this quite important thing 😉  My code works as it should now.

Kær kveðja / Best Regards,

Hello,

You seem to have the type of the arguments wrong. It should rather be:

Pkt4Ptr query4;
Lease4CollectionPtr leases4;
Lease4CollectionPtr deleted_leases4;

We implemented collection of leases in this hook point for DHCPv4 to keep parity with DHCPv6. In most cases, these collections will store at most one lease.
