Answer:
They are not always right or the most accurate.

<u>Classless Inter-Domain Routing</u> gets its name from the notion that it ignores the traditional A, B, and C class designations for IP addresses and can therefore set the network-host ID boundary wherever it wants to, in a way that simplifies routing across the resulting IP address spaces.
<u>Explanation</u>:
A router is a networking device that helps in connecting multiple networks. <em><u>Classless Inter-Domain Routing (CIDR) </u></em>is used for creating IP addresses and IP routing. CIDR was introduced in the year 1993 by <em><u>“The Internet Engineering Task Force”</u></em>. The classful network design was replaced by CIDR in the Internet.
The IP addresses are responsible for sending the particular information packets to specific computers. Classless inter-domain routing helps in improving the allocation of IP addresses.
