Description

If the ipaddress is not the address range start, it's not masked to turn it into that. So 1.2.3.4/24 is not stored as address 1.2.3.0 with netmask 24, but as 1.2.3.4 with netmask 24. This is then propagated into the radix tree, where it is used as an exact key in exact lookups, giving unexpected results.
