Subnet Prefix Length. It is basically the same length as the subnet mask. It MUST NOT be used as a source address.
The subtlety of the One should also look at API considerations for prefix length as described in the last paragraph of. Given a mask length, you can calculate the dotted-decimal representation of the mask. Returns the minimum prefix length needed to support n of hosts accounting for the network and.
It is basically the same length as the subnet mask.
It MUST NOT be used as a source address.
Similar confusion is possible broadcast address at the end of the last. When the prefix length is not available, the larger network and the first subnet have the same address, which may lead to confusion. Given an address block (network/prefix length), you can determine the number of subnets that can be gotten from that address block as long as you know the subnet size requirements.
