Hello Khan,

a)

permit 192.168.8.0 0.0.7.255


and


permit 192.168.8.0 0.0.7.0


do different things although in some special cases the second could be used with the same results but no guarantees ...


b)

I don't understand what you mean

I try to guess

if these are the the same octect:

0000 1000

0000 1110


0000 0 match and must match

the last bit match and must match


0000 1000 base address

0000 0110 wildcard mask


hope to help

Giuseppe
