ip subnet zero

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 addres

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

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

from 224 to 239. the first byte of the Class d ip address starts with "1110". It is a specially reserved address. It does not point to a specific network. Currently, this type of address is used in multi-point broadcast (Multicast. A multicast address is used to address a group of computers at a time. It identifies a group of computers that share the same protocol. Multicast over an IP network is generally

. Therefore, the subnet mask should be set based on the size of the network.If a network of no more than 254 computers, the use of "255.255.255.0" as a subnet mask, and now most of the local area network will not exceed this number, so "255.255.255.0" is the most commonly used IP address subnet mask , I see the largest

. 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
