Computer Networks - IP Addressing

In CIDR notation, what does the suffix number after the slash indicate about the network?

AThe number of bits used for the network prefix

BThe total number of hosts in the network

CThe number of subnetworks available

DThe maximum number of routers allowed

Step-by-Step Solution

Solution:

Step 1: Understand CIDR notation
CIDR notation uses a slash followed by a number to indicate the network prefix length.
Step 2: Interpret the suffix number
The number after the slash specifies how many bits in the IP address are fixed for the network portion.
Final Answer:
The number of bits used for the network prefix -> Option A
Quick Check:
Suffix number = network prefix length [OK]

Quick Trick: Suffix number shows network prefix bits [OK]
