What is a Class A subnet?

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. … Class B networks use a default subnet mask of 255.255.

What is a Class A IP address 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 is class A IP range?

x.x.x only. The IP range 127. 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 Class A network?

Class A. 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.

How many types of IP are there?

four typesAn internet protocol (IP) address allows computers to send and receive information. There are four types of IP addresses: public, private, static, and dynamic.

What are the 3 major classes of an IP network?

Currently there are three classes of TCP/IP networks. Each class uses the 32-bit IP address space differently, providing more or fewer bits for the network part of the address. These classes are class A, class B, and class C.

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

The striking difference is the total number of hosts that a network can have in class A, B and C. This network is 8-bit network prefix. Its highest bit is set to 0, and contains a 7-bit network number and a 24-bit host number. … The class A network address block contains 2 31 power (2,147,483,648) individual addresses.
