A network with 6 bits remaining for the host portion will have how many usable host addresses?

There are 6bits in host portion , so possible host addresses are 2⁶ = 64,

so there are 64 addresses are possible

but, onlyt 62 addresses are usable, because

1)first address is used as network id: that is all six bits are zeros :000000

2)last address is used as broadcast address : that is all six bits are ones : 111111

so, only 62 addresses are usable..
