Question No. 1
Suppose a multinational company has a computer network between its head office and a sub-office. The head office is currently using the IP address (220.127.116.11) of class C whereas the sub-office is using the IP address (18.104.22.168) of class B. Due to increase in number of its employees, the company wants to create further subnets as per following requirements:
For Head Office, 12 subnets each having 9 hosts
For Sub-office, 136 subnets each having 240 host
Considering the above mentioned scenario and requirements, you are required to answer the following questions in the given table:
Sr. No Question Answer
1 What will be the Subnet mask to fulfill the demand of number of subnets and hosts for head office? 255.255.255.240
2 How many bits will be borrowed to create the required number of subnets for the head office? 4 Bits
3 What will be the valid range of host address in the 4th subnet of head-office? 22.214.171.124
4 What will be the Subnet mask to fulfill the demand of number of subnets and hosts for sub- office? 255.255.255.0
5 How many bits will be borrowed to create the required number of subnets for the sub-office? 8 Bits
Suppose Alpha-Tech company has a computer network and assigned a class B network address 126.96.36.199 and subnet mask as 255.255.0.0. In order to deal with the host requirements, the company wants to perform subnetting among its departments i.e. Admin, Account, Sales, HR and IT having the hosts requirements as 30, 320, 250, 120 and 54 respectively.
Considering the above mentioned scenario and requirements, you are required to fill the following table:
Departments Required No. of Hosts No. of Bits for subnetting Subnet mask
Admin 30 11 255.255.255.224
Account 320 7 255.255.254.0
Sales 250 8 255.255.255.0
HR 120 9 255.255.255.128
IT 54 10 255.255.255.192
Best of Luck!
