What is the function of subnet mask

A subnet mask is an IP mask used to divide network addresses and host addresses. Its functions include: 1. Divide the network. By dividing different networks, network resources can be managed more effectively and network congestion and conflicts can be reduced. 2. Network security can be improved. By using subnet masks, a large network can be divided into Multiple small networks to achieve network isolation and security; 3. Optimize network performance. By properly configuring subnet masks, network broadcasts and conflicts can be reduced, thereby improving network performance and reliability.

What is subnet mask

A subnet mask is a 32-bit address that is used to mask a part of an IP address to distinguish network identification and host identification, and to indicate whether the IP address is on a LAN or a WAN. The subnet mask can indicate which bits of an IP address identify the subnet where the host is located, and which bits identify the host's bit mask; the subnet mask cannot exist alone, it must be used in conjunction with the IP address.

What is the relationship between subnet mask and ip address?

The relationship between subnet mask and IP address: 1. Subnet mask is used to determine whether the IP addresses of two computers belong to the same subnet. That is, the relationship between subnet mask and IP address can determine the unique address; 2. Convert the subnet mask and the IP address into binary and perform the AND algorithm, which is the only external address; 3. The subnet mask can be used to distinguish the network address and the host address.

What is the subnet mask for a Class C address?

The subnet mask of the Class C address is [255.255.255.0]. The subnet mask is also composed of a 32-bit binary number, which defines how many of the 32 bits of the IP address are used to identify the network, so the subnet mask cannot exist independently of the IP address.

What is the default subnet mask for class A addresses?

The default subnet mask of a class A address is 255.0.0.0, which means setting all host-ids of the network address to 0 and setting all net-ids to 1 to obtain information about whether the IP address is subnet divided.

What is the default subnet mask for Class B IP addresses?

The default subnet mask of Class B IP address is "255.255.0.0"; the first and second bytes of Class B address are the network address, the other 2 bytes are the host address, and the first 2 bytes of the other 1 byte are is fixed at 10; in class b addresses, "172.16.0.0" to "172.31.255.255" are private addresses.

What is the subnet mask for a Class A network?

The subnet mask of a Class A network is "255.255.255.0". Subnet mask is a virtual IP technology produced in order to solve the problem of IP address allocation under the background of shortage of IPv4 address resources. The three types of addresses A, B, and C are divided into several subnets through the subnet mask, thus significantly improving the efficiency of IPv4 address allocation. IP address allocation efficiency; the default subnet mask of Class A is "255.0.0.0", the default subnet mask of Class B is "255.255.0.0", and the default subnet mask of Class C is "255.255.255.0" .

What is the subnet mask for a Class C IP address?

The subnet mask of a Class C address is "255.255.255.0". Class C IP address refers to the four segments of the IP address. The first three segments are the network number, and the remaining segment is the number of the local computer. The default subnet mask of the Class C IP address is 255.255.255.0. The maximum number of hosts supported by the network is 256-2=254
