Determine the subnet information for the next largest network segment or segments.
Step 3.
In this case, the two Branch1 LANs are the next largest subnets.
How many IP addresses are needed for each LAN?

What is the smallest-size subnet that can be used to meet this requirement?
/27
2.
What is the maximum number of IP addresses that can be assigned in this size sub-
net?

3.
Assign subnets to BRANCH1 LANs.
Step 4.
Start with the IP address following the HQ LAN subnets.
Assign the next subnet to the Branch1 LAN1.
