WebApr 4, 2024 · Because that mask is used with a Class B address(130.4.102.1), implying 16 network bits, there are 6 remaining subnet bits. In the second example, the mask has only five binary 0s, for 5 host bits. Because the mask is used with a Class C address, there are 24 network bits, leaving only 3 subnet bits. The process so far is straightforward: WebThe borrowed bits are the host bits in the default subnet mask that are used for network in the custom subnet mask. In your example: Last byte of the default subnet mask: Binary Decimal 00000000 -> 0. Last byte of the custom subnet mask: Binary Decimal 11110000 -> 240. The first four (4) bits go from host to network, they are borrowed bits.

WebAug 25, 2024 · The 24 means there were 24 bits set to 1 in the subnet mask. These are used for the network ID and the subnet ID. These are counted from the left. The bits set to 1 will be an unbroken sequence of 1’s. There cannot be any 0 bits among them. We know 8 bits set to 1 in binary gives us 255 in decimal. So 24 means three sets of 8 bits all set to 1.
