WebAug 22, 2024 · In subnetting, bits are ‘borrowed’ from the host ID to create a subnet. If you only borrow one bit, you have the possibility to create exactly two subnets, because only 0 or 1 are possible. For further subnets, more bits must be released, leaving fewer places for host addresses. IP addresses with a subnet look exactly the same as those without. WebIf the network administrator has decided to borrow 3 bits from the host byte for subnets, this leaves 5 bits for host addresses.
