Question

Weber State University is given an IP addresses block of 138.192.0.0 /16. There are 7 colleges (Applied Science, Arts & Humanities, Business & Economics, Education, Health, Science, and Social & Behavioral Science) and 4 divisions (Administrative Services, Facilities Management, Information Technology, and Student Services). The University has found that it needs to divide its network up evenly among all of the groups. Complete the following information to show how you would divide the network.

For each department give an Organization Network Address and a Subnet Mask

Colleges:
Applied Science

Arts & Humanities

Business & Economics

Education

Health

Science

Social & Behav. Science

Divisions:

Administrative Services

Facilities Management

Information Technology

Student Services

Explanation / Answer

Here given address is 138.192.0.0/16.

Then the subnet mask will be 255.255.0.0

Given /16 means 32-16=16 bits will be zero from right side.

Here we require to split the network into 11 groups.

For 11 we require 4 bits,because in binary conversion of 11 fourth bit is also set.

Therefore ,the new subnet mask for each group is 255.255.240.0

Since first 4 bits are set in 3 byte,therefore 240

For Applied Science College- Subnet mask=255.255.240.0 Network address(First address)=138.192.0.0 and last address=138.192.15.255

For Arts and Humanities College- Subnet mask=255.255.240.0 Network address(First address)=138.192.16.0 and last address=138.192.31.255

For Business and Economics College- Subnet mask=255.255.240.0 Network address(First address)=138.192.32.0 and last address=138.192.47.255

For Education- Subnet mask=255.255.240.0 Network address(First address)=138.192.48.0 and last address=138.192.63.255

For Health College- Subnet mask=255.255.240.0 Network address(First address)=138.192.64.0 and last address=138.192.79.255

For Science College- Subnet mask=255.255.240.0 Network address(First address)=138.192.80.0 and last address=138.192.95.255

For Social and Behav. Science College- Subnet mask=255.255.240.0 Network address(First address)=138.192.96.0 and last address=138.192.111.255

For Administrative Services - Subnet mask=255.255.240.0 Network address(First address)=138.192.112.0 and last address=138.192.127.255

For Facilities Management- Subnet mask=255.255.240.0 Network address(First address)=138.192.128.0 and last address=138.192.143.255

For Information technology- Subnet mask=255.255.240.0 Network address(First address)=138.192.144.0 and last address=138.192.159.255

For Student Services- Subnet mask=255.255.240.0 Network address(First address)=138.192.160.0 and last address=138.192.175.255
