IP Addressing/Subnet Masking Problems



1. Classify the following IP addresses as A, B, or C and label the network and host parts of the IP address: 99.1.1.0, 156.1.149.9, 171.13.5.233, 127.1.1.255, 193.4.14.1

2. Say you are assigned a Class C network number of 200.133.175.0 (apologies to anyone who may actually own this domain address:). You want to utilize this network across multiple small groups within an organization. You can do this by subnetting that network with a subnet address. Break this network into 14 subnets of 14 nodes each.

3. Given IP Address 171.68.235.228: What class is it? Which parts of the address are network and which are host? What are the network and host numbers, in binary?
    What is the lowest host IP address (in decimal) on this network? What is the highest host IP address (in decimal) on this networlk?

4.Given an IP address of 172.16.0.0, what would be the default subnet mask? The subnet mask if 2 bits are borrowed? 3 bits? 4 bits? Justify your answer.

5.  A host has an IP Address of 156.1.149.9 and a subnet mask of 255.255.255.0, what is the subnetwork on which this host resides?

6.  Given the IP address 156.1.128.200 with a subnet mask of 255.255.224.0. Answer the following:

    4. How many subnets have been created?
    5. How many host address per subnet?
7.  Given the IP address 199.199.199.172 with a subnet mask of 255.255.255.192. Answer the following:

9.  Given the IP address 45.208.245.222 with a subnet mask of 255.248.0.0. Answer the following:
    1. What is the subnet address of the network containing the given IP address?
    2. What is the broadcast address of the network containing the given IP address?
    3. How many bits were borrowed?
    4. How many subnets have been created?

  1. Suppose you are given the IP address 195.5.5.0 and wish to connect Springfield and Bedrock to Southpark. Create an IP addressing scheme that will meet the following requirements:
A: Each subnet must support between 25 and 30 devices.

B: You must have enough subnets to address each network.
  1. What is the subnet mask for this network? _____________________________
  2. What is the broadcast address of the 3rd subnet? _________________________
  3. On the diagram, assign a subnet address to each network and give each router interface an appropriate IP address for that network.
