The Purpose of Subnetting in IP Addressing

Subnetting is a crucial technique in IP addressing that helps in efficiently managing and optimizing network resources. By dividing a larger network into smaller subnetworks, subnetting enables better organization, allocation of IP addresses, and improves network performance.

For Network Engineer L1 interviews, understanding subnetting is essential as it allows for more efficient use of IP addresses, reduces network congestion, and enhances security by segmenting traffic. Subnetting also facilitates routing and simplifies network troubleshooting.

Mastering subnetting is key for Network Engineers as it enables them to design and maintain networks that are scalable, secure, and optimized for performance.
