Solution

The main reason Classless Inter-Domain Routing (CIDR) is helpful in modern networking is that it allows for more arbitrary network sizes.

Here's a step-by-step explanation:

  1. Traditional IP addressing uses classful network design, which allocates IP addresses in blocks of fixed sizes. This can lead to inefficiencies and waste if a network doesn't need the exact number of addresses in a block.

  2. CIDR, on the other hand, is classless. This means it doesn't restrict IP address allocation to fixed blocks. Instead, it allows networks to be divided into varying sizes, depending on their specific needs.

  3. This flexibility makes CIDR more efficient and scalable than classful network design. It helps to reduce the waste of IP addresses and can accommodate a wider range of network sizes.

  4. Therefore, the main benefit of CIDR in modern networking is its ability to allow for more arbitrary network sizes.
