WebJan 15, 2024 · Using this table, we can determine that we need a minimum subnet size of /27 to support 25 hosts, /29 to support 4 hosts, /25 to support 120 hosts, and so on. Tip: When designing subnets, think about the future expansion of the network. Using a /27 to support a network that needs 30 hosts does not allow for expansion. WebSo if the goal is 7 subnets, start counting up powers of two: 2, 4, 8. At the third power, you reach 8. So that means that you will need to use 3 bits of subnetting in order to create that many subnets. /24 + 3 = /27. You move the network portion of the address three bits to the right to create your new subnets.

WebIf you borrow 10 bits from a Class B network, you can create 2^10 = 1024 subnets. Explanation: Here's how to calculate it: A Class B network uses the first 16 bits for the network portion, and the remaining 16 bits for the host portion. WebOf course, you can also mix them, because every subnet can be re-subnetted; so you could f.e. have a /27 subnet using up the first 32 addresses, and two /28 subnets using the remaning 32 ones, dividing them in two blocks of 16 addresses.
