Task 1: Subnet the Address Space

Examine the network requirements.

Step 1.

The addressing for the network has the following requirements:

The ISP LAN will use the 209.165.202.128/27 network.

■

The link between the ISP router and the HQ router will use the 209.165.200.224/30
network.

■

The 192.168.1.0/24 network must be subnetted for use in the HQ LAN and the link
between the HQ and BRANCH routers. The HQ LAN will require 50 host IP address-
es.

■

The BRANCH LAN will use the 10.10.2.0/23 network.

■

Consider the following questions when creating your network design: Step 2.

How many subnets need to be created from the 192.168.1.0/24 network? 2

What is the subnet mask for this network in dotted decimal format? 255.255.255.192

What is the subnet mask for the network in slash format? /26

What are the network addresses of the subnets?

Subnet 0: 192.168.1.0/26

Subnet 1: 192.168.1.64/26

Subnet 2: 192.168.1.128/26

How many usable host IP addresses are there per subnet? 62

How many usable hosts IP addresses are available in the BRANCH LAN? 510
