Combining two or more networks into a single network is known as:

• A. Subnetting
• B. Supernetting
• C. IP Aggregation
• D. Network Merging

Answer: (B)

Supernetting is the process of combining two or more adjacent networks into one larger network by using a shorter subnet mask. This lets a single route cover multiple subnets, which reduces the number of entries routers must keep in their tables and helps with scalable routing. For example, two contiguous networks like 10.0.0.0/24 and 10.0.1.0/24 can be summarized as 10.0.0.0/23, since the first 23 bits are common. Subnetting, in contrast, splits a network into smaller pieces, increasing the number of routes. IP aggregation is a broader term for summarizing routes, and while it describes the goal, the specific term for merging networks into a larger one is supernetting. "Network merging" isn’t a standard routing term.
