Why does the default subnet mask not fit the needs of the organization?
In some scenarios, the default subnet mask values do not fit the needs of the organization, because of the physical topology of the network, or because the numbers of networks (or hosts) do not fit within the default subnet mask restrictions. The next section explains how networks can be divided using subnet masks.

What are subnet classes?
Classes A, B, and C are used the most often by different networks. Subnet classes are made unique by the number of bits their IP addresses have dedicated to a network and the number of bits dedicated to hosts. They each have a default subnet mask. Classes can be identified by the number in the first octet of their address.
Which IP address is best for a large network?
Accordingly, Class A IP addresses are best used to serve incredibly large networks. In comparison to Class A, Class B IP addresses are better suited to serving smaller networks since they reserve 14 bits for a network, which leaves only 18 bits for hosts. Network addresses for these range from 128 to 191.
What is IP subnet?

What is IP protocol?
Internet Protocol (IP) is a network layer, host-to-host delivery protocol. It means it delivers a packet from one host to the other with no knowledge about the ports within the host. It is a connection-less protocol that makes it unreliable. Hence, it is often clubbed with TCP.
Can two hosts have the same IP address?
Two hosts in the same network have the same network ID part but different host ID part. You can also write a Python program to validate the IP address. On the basis of this division, IP addresses are classified into various classes.
What are the two parts of IP address?
Parts of IP address. IP Address is divided into two parts: Prefix: The prefix part of IP address identifies the physical network to which the computer is attached. . Prefix is also known as a network address . Suffix: The suffix part identifies the individual computer on the network.
What is class E IP address?
Class E IP address is defined by including the starting four network address bits as 1, which allows you two to incorporate addresses from 240.0.0.0 to 255.255.255.255. However, E class is reserved, and its usage is never defined. Therefore, many network implementations discard these addresses as undefined or illegal.
