Questions & Step-by-Step Solutions
How many subnets can be created from a /24 network if 3 bits are borrowed for subnetting?
Step 1: Understand what a /24 network means. A /24 network has 24 bits for the network part and 8 bits for the host part (since there are 32 bits in total).
Step 2: Identify how many bits you are borrowing for subnetting. In this case, you are borrowing 3 bits.
Step 3: Calculate the number of subnets created by borrowing bits. Use the formula 2^n, where n is the number of bits borrowed. Here, n = 3.
Step 4: Calculate 2^3, which equals 8. This means you can create 8 subnets.
Step 5: Conclude that by borrowing 3 bits from a /24 network, you can create 8 subnets.
Subnetting – Understanding how to divide a network into smaller sub-networks by borrowing bits from the host portion of the IP address.
CIDR Notation – Knowledge of Classless Inter-Domain Routing (CIDR) and how subnet masks are represented in the format /n.
Exponential Growth of Subnets – Recognizing that the number of subnets created is a power of 2 based on the number of bits borrowed.
