[*] create table 12: rc=0
[*] empty table:
    test 1.2.3.4    -> rc=-1  (not found)
[*] append 10.1.2.0/24: rc=0
    test 10.1.2.9   -> rc=0  (FOUND in table)

    test 99.0.0.1   -> rc=0  (FOUND in table)
    test 200.1.1.1  -> rc=-1  (not found)
[*] after /33: 99.0.0.1 matches (stored as 0.0.0.0/1 catch-all)
    while 200.1.1.1 does not -- the unbounded shift stored the
    wrong mask and it is live in the lookup tree.
