What subnet ID and broadcast address of each subnet if you divide a class B network (150.10.0.0 – 150.10.255.255) in 4 different subnets. What is the new subnet mask?
What subnet ID and broadcast address of each subnet if you divide a class B network (150.10.0.0 – 150.10.255.255) in 4 different subnets. What is the new subnet mask? [5]
- Network: 150.10.0.0 to 150.10.255.255 - Network Address: 150.10.0.0 - Class B default mask: 255.255.0.0 (/16) - Host bits: 16 (last two octets) - Required subnets: 4 --- $$2^n \geq 4 \implies n = 2 \text{ bits}$$ Borrow 2 bits from the host portion (third octet). --- New prefix = $16 + 2 = /18$...
