Write the subnet ID and broadcast address of each subnet if you divide a class C network (192.168.3.0 – 192.168.3.255) into 4 different subnets. What is the new subnet mask?
Write the subnet ID and broadcast address of each subnet if you divide a class C network (192.168.3.0 – 192.168.3.255) into 4 different subnets. What is the new subnet mask? [5]
- Network: 192.168.3.0 - 192.168.3.255 (Class C, default mask /24 = 255.255.255.0) - Required subnets: 4 --- To create 4 subnets: $$2^n \geq 4 \implies 2^2 = 4 \implies n = 2 \text{ bits}$$ Borrow 2 bits from the host portion. --- Original: Borrow 2 host bits: New Subnet Mask = 255.255.255.192 (/...
