ACTIVITY 04 – Subnettting
A. Background / Scenario
Subnetting is the process of stealing bits from the HOST part of an IP address in order to
divide the larger network into smaller sub-networks called subnets. After subnetting, we
end up with NETWORK SUBNET HOST fields. We always reserve an IP address to
identify the subnet and another one to identify the broadcast subnet address.
Company XYZ wants to conserved IP address. This company is having a network space
of 150.100.0.0. This company hired you to compute on the number of usable subnets and
usable host on their network.
B. Determine the number of subnet
Company XYZ required 2000 subnets.
Solve for:
Number of bits borrowed: 11
Usable subnets: 2046
Subnet Mask:
Slash format: /27
CIDR format: 255.255.255.224
Usable host / subnet: 30
Magic number or change per network (delta ) : 32
C. Determine the number of host / subnet
Company XYZ required 1000 host / subnet.
Solve for:
Number of bits borrowed: 10
Usable subnets: 1022
Subnet Mask:
Slash format: /26
CIDR format: 255.255.255.192
Usable host / subnet: 62
Magic number or change per network (delta ) : 64
