Question: What Are The 3 Major Classes Of An IP Network?

What is a Class A network used for?

Class A IP addresses are used for huge networks, like those deployed by Internet Service Providers (ISPs).

Class A IP addresses support up to 16 million hosts (hosts are devices that connect to a network (computers, servers, switches, routers, printers…etc.).

What are the 3 classes of subnet mask?

The three default subnet masks are 255.0. 0.0 for Class A, 255.255. 0.0 for class B, and 255.255. 255.0 for Class C.

What is a Classful subnet?

Classful subnetting is a method of splitting a classful network number into two or more smaller subnets. The subnets will all be the same size, determined by the maximum number of hosts per subnet. A single custom subnet mask is used to configure the subnets.

What is class A network range?

Class A Address Thus the first octet ranges from 1 – 127, i.e. Class A addresses only include IP starting from 1. … x.x.x is reserved for loopback IP addresses. The default subnet mask for Class A IP address is 255.0. 0.0 which implies that Class A addressing can have 126 networks (27-2) and 16777214 hosts (224-2).

What is standard subnet mask?

Most home networks use the default subnet mask of 255.255. 255.0. … Large networks with several thousand machines may use a subnet mask of 255.255. 0.0. This is the default subnet mask used by Class B networks and provides up to 65,536 IP addresses (256 x 256).

What is class full IP address?

A classful network is a network addressing architecture used in the Internet from 1981 until the introduction of Classless Inter-Domain Routing in 1993. The method divides the IP address space for Internet Protocol version 4 (IPv4) into five address classes based on the leading four address bits.

What are Class C networks?

Class C Network Definition. A Class C network is any network in the 32-bit, IPv4 addressing scheme whose first three bits, the so-called high-order bits, are 110. … The number of bits used to identify the network and the host (i.e., computer attached to the network) vary according to the network class of the address.

What is a Class C subnet?

A class C network would have a subnet mask of 255.255. 255.0 which means that 24 bits are used for the network. In CIDR notation this is designated by a /24 following the IP address. So: IP address 192.168.

What are class AB and C networks?

A B and C Classes of Networks. Internet addresses are allocated by the InterNIC (http://www.internic.net ), the organization that administers the Internet. These IP addresses are divided into classes. The most common of these are classes A, B, and C. … Class A networks use a default subnet mask of 255.0.

What is a 192.168 IP address?

Using 192.168. 192.168. 0.0 is the beginning of the private IP address range that includes all IP addresses through 192.168. … One common IP address assigned to home routers is 192.168. 1.1. This IP address is used because the router is on the 192.168.

What is the difference between Class A Class B and Class C networks?

If the address is written in decimal format, the first number determines the address. If the first number is between 0 and 127 inclusive, the address is class A. If the first number is between 128 and 191 inclusive, the address is class B. If the first number is between 192 and 223 inclusive, the address is class C.

What is class A subnet mask?

Class A networks use a default subnet mask of 255.0. 0.0 and have 0-127 as their first octet. The address 10.52. 36.11 is a class A address. Its first octet is 10, which is between 1 and 126, inclusive.

What are the different classes of IP addresses?

TCP/IP defines five classes of IP addresses: class A, B, C, D, and E. Each class has a range of valid IP addresses. The value of the first octet determines the class. IP addresses from the first three classes (A, B and C) can be used for host addresses.

What are Class A networks?

Class A addresses are IP addresses that are assigned to network devices, such as computers, and include all addresses in which the first bit of the first octet is set to 0 (zero). This includes all values from 00000001 to 01111111, or 1 to 127.
