Q: What is the primary benefit of CIDR in contemporary networking?
- CIDR increases network security with no additional resources
- CIDR simplifies MAC address assignment
- CIDR lowers the amount of power needed to run a server
- CIDR allows for more arbitrary network sizes
Explanation: Without respect to the conventional class borders, CIDR makes it possible to split networks into smaller, more adaptable blocks of addresses, which in turn makes it possible to allocate IP addresses more efficiently. Because of this flexibility in address distribution, companies can make more efficient use of address space, which helps them avoid wasting address space and ensures that they can scale more efficiently. CIDR also makes it easier to aggregate IP prefixes, which helps decrease the size of routing tables and enhances the efficiency of routing on the Internet. This is another benefit of CIDR.
