IP subnet addressing All Hosts must support subnet addressing (rfc950 [mogulandpostel1985]). IThe P address is simply composed of a network number and a host number. Instead, the host number is divided into a sub-network number and a host number.The reason for this is that Class A and Class B addresses allocate too much space for the master host number, and the n
. here the network range ends in the previous one, that is, 10.0.31.255. Chart Note that the number of hosts doubles as the subnet size increases by one binary bit. the smallest step represents eight binary bits. The eight binary bits contain a subnet of 256 hosts. However, because you cannot use the first or last IP
The subnet mask cannot exist alone, it must be used in conjunction with an IP address. The subnet mask has only one function, which is to divide an IP address into two parts: network address and host address.The subnet mask setting must follow certain rules. The same as the
. Therefore, any IP address whose first byte is greater than 223 or less than 240 is a multicast address. Each byte of the IP address is 0 ("0.0.0.0") and corresponds to the current host; each byte of an IP address is 1. The IP address ("255.255.255.255") is the broadcast address of the current
than 240 is a multicast address. Each byte of the IP address is 0 ("0.0.0.0") and corresponds to the current host; each byte of an IP address is 1. The IP address ("255.255.255.255") is the broadcast address of the current subnet. All IP addresses with "11110" are reserved
International regulations: divide all IP addresses into A, B, C, D, and E. Class DefaultSubnet Mask: Class A is 255.0.0.0; Class B is 255.255.0.0; Class C is 255.255.255.255.0. The subnet mask is a 32-bit address. It is used to shield a part of the IP address to distinguish the network ID and host ID, and shows whether the IP

Ip subnet-zero and ip classless usage if you have a class c ip address, such as 192.168.10.0, you want to divide it into eight CIDR blocks, each of which can contain 32 hosts, subnetmask is: 192.168.10.0-31, broadcast address: 192.168.10.31 192.168.10.32-63, broadcast address: 192.168.10.32, broadcast address: 192.168.
