The subnet number is 128.12.32.0, with a maximum of 16 subnets, a maximum of 4096 hosts, and an address range of 128.12.32.0 - 128.12.47.255.
Explanation:
Subnet numbers are used to determine to which subnet a given IP address really belongs. If you want to build more subnets than that, you'll need a bigger address space. You can only use that many hosts in a single subnet. If you know the address range for a subnet, you'll know what addresses may be used inside that network.
Subnet mask for address 128.12.34.71 is 128.12.32.0, highest amount of subnets is 16, max number of nodes is 4096, and address range is 128.12.32.0 - 128.12.47.255.
