Quick Answer: What Is A Class A Network Used For?

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 C in IP address?

Class C Address Class C IP addresses range from 192.0. … The default subnet mask for Class C is 255.255. 255. x. Class C gives 2097152 (221) Network addresses and 254 (28-2) Host addresses.

What does a Class A network address indicate?

Class A Network Numbers A class A network number uses the first eight bits of the IP address as its “network part.” The remaining 24 bits comprise the host part of the IP address, as illustrated in Figure 3-2 below.

What is a class B network used for?

A Class B network was a network in which all addresses had the two most-significant bits set to 1 and 0 respectively. The pool of unassigned Class B addresses was rapidly depleted. Sixteen contiguous class B networks are reserved for private network addresses.

Who uses Class A IP addresses?

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 a Class A subnet?

A Class A IP address reserves 8 bits for a network with 24 bits dedicated to hosts. Its IP address spans from 0 to 126. The Class A subnet mask is 255.0. 0.0. Accordingly, Class A IP addresses are best used to serve incredibly large networks.

How many hosts are part of Class A networks?

Class A Network (/ 8 Prefixes) Each network supports a maximum of 16,777,214 (2 24 -2) hosts per network. You must subtract two because the base network represents host “0”, and the last host on the network is actually used for 1s (“broadcast”) and may not be assigned to any host.
