Borrow 12 bits from where?
Each octect is 8 bits. So Class A networks, the "10." uses 8 bits, leaving 24 bits to use between subnet and hosts. so if you use 12 bits for subnets, you have 12 bits for hosts or:
subnets - 4096
hosts - 4094 -

ok 16 bits, for subnets?
if so, that means the "Class A" uses 8 bits.
and i guess you mean 16 for subnets so 16 bits for subnets
leaving 8 bits for hosts
for:
subnets = 2^16 or 65536 subnets
hosts = 2^8 or 254 hosts -

So 16 is your mask? 255.255.0.0?
Your range would be 10.0.0.1 - 10.0.255.254 -
