Subnetting vs. Supernetting: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Published on February 10, 2024
Subnetting divides a network into smaller segments, enhancing organization and security, while supernetting combines multiple networks into a larger one for simplified management.

Key Differences

Subnetting involves dividing a larger network into smaller, more manageable subnetworks. This process increases network efficiency and security by reducing congestion and isolating network segments. Supernetting, on the other hand, is the practice of combining multiple smaller networks into a larger, aggregated network. It simplifies network management and address allocation by creating a larger address space from smaller ones.

In subnetting, IP addresses are segmented into subnetworks, allowing for finer control over traffic flow and access within a network. This leads to improved performance and security. Supernetting, conversely, reduces the number of routing entries in a routing table by aggregating multiple networks, thereby simplifying the routing process and conserving IP addresses.

Subnetting is often used within organizations to create distinct networks for different departments or functional areas, enhancing security and control. Supernetting is more commonly used by Internet Service Providers (ISPs) and large organizations to efficiently use IP address space and simplify network routing.

The technical process of subnetting involves creating smaller networks by manipulating the subnet mask of an IP address. This allows for the creation of multiple subnetworks within a single network. In supernetting, the process involves expanding the network by combining multiple IP addresses or networks, effectively creating a larger network with a single subnet mask.

Subnetting is essential for large networks to avoid broadcast traffic overload and to create isolated network segments for security. Supernetting, in contrast, is key to efficient IP address management, especially with the limited availability of IPv4 addresses, and helps in reducing the complexity of routing tables in large networks.
