Addresses Homework Problems
Subnetting and CIDR
Use the above diagram and the IP address 220.127.116.11 for the following questions. Use twelve bits for each subnet (beyond the original network address bits).
Assume each “Net x” in the diagram is a subnet of the main network.
1. Assign a subnet address and subnet mask to each of the five networks.
2. List the lowest and highest address in each subnet that can be assigned to a node in the subnet.
3. Assign an IP address to each router interface, using the lowest address in each block of addresses for the router interface in that subnet (if a subnet has multiple routers, use the first x number, where x is the number of routers in the subnet).
You have a network that has been assigned the network address of 18.104.22.168 /20. You need to create subnets to support 100 hosts each. Provide solutions for each of the following.
Number of bits for subnets:
Number of bits for hosts:
Total number of subnets:
Total number of hosts per subnet:
CIDR Network IP address for the first subnet:
Broadcast address for the first subnet:
First IP address for a node on the first subnet:
Last IP address for a node on the first subnet:
