Ecco la correzione:
q: 128.127.128.127/15
a: 128.126.0.0 - 128.127.255.255

Per l'anding eccolo (non lo avevo cancellato):

128.127.128.127/255.255.255.64
10000000 (128)    01111111 (127)    10000000 (128)    01111111 (127)
11111111 (255)    11111111 (255)    11111111 (255)    01000000 (64)
-----------------------------------------------------------------------------------------------------
10000000 (128)    01111111 (127)    10000000 (128)    01000000 (64)

10000000 (128)    01111111 (127)    10000000 (128)    01111111 (127)
00000000            00000000             00000000            10111111
-----------------------------------------------------------------------------------------------------
10000000 (128)    01111111 (127)    10000000 (128)    11111111 (255)

Quindi, se non mi sono sbagliato,
128.127.128.64 - 128.127.128.255
