Problem 4
Problem 4: IP Addresses You have been hired as part of a team to set up a computer network for a small company in Vermont. You expect to have three buildings in your company, and you need to: (25 points) a) Request from your ISP (such as Comcast or Verizon) a range of IP addresses to provide for all the employees in the company (their office equipment as well as personal phones and tablets they may bring from home) b) Set up three additional subnets within this range, one subnet for each building. Company Information 250 employees and you want to allow for each employee to have 5 IP addresses (this is generous, and so also accounts for printers, visitors, and all other IP needs) · The three buildings will hold i. 50 employees ii. 30 employees iii. 170 employees You know a local café has assigned you the IP address of 45.42.168.23 when you are in the café, so you expect to have your company's IP address range to have the same higher order bits (you need to figure out how many) as this café IP address (since your company will be geographically close to the café). Your task (to hand in for the exam): What is the network mask you request from your ISP (the Comcast or Verizon type company in the region)? How many addresses does this provide you with? Within this range, what are the subnet masks you assign to each building in your company? a) b) c) d) How many IP addresses are you providing to each building?Explanation / Answer
A) As the IP address 45.42.168.23 belongs to class A and the required number of IP addresses for the given query are
= 50 + 30 + 170
= 250 IP addresses
Hence, the netmask which best supports 250 IP addresses without much wastage of addresses is:
= 255.255.255.0.
Using this netmask, we can have 16 subnets and 254 hosts per subnet, and here we require IP addresses for 250 hosts.
B) This netmask provides us 254 IP addresses.
C) For building with 50 employees, the subnet mask would be : 255.255.255.192, as this netmask contains total of 64 addresses out of first is network address and last is broadcast address, while remaining 62 addresses are available for usage by hosts.
For building with 30 employees, the subnet mask would be : 255.255.255.224, as this netmask contains total of 32 addresses out of first is network address and last is broadcast address, while remaining 30 addresses are available for usage by hosts.
For building with 170 employees, the subnet mask would be : 255.255.255.0, as this netmask contains total of 256 addresses out of first is network address and last is broadcast address, while remaining 254 addresses are available for usage by hosts.
D) The provided IP addresses for building with 50 employees are: 62 IP addresses.
The provided IP addresses for building with 30 employees are: 30 IP addresses.
The provided IP addresses for building with 170 employees are: 254 IP addresses.
