Computer Networks And Internet Protocol - Week 6 Assignment 6 | NPTEL | JAN 2023

Computer networks and internet protocol - week 6 | assignment 6 : answer with explanation.

Computer Networks And Internet Protocol - Week 6 Assignment 6  NPTEL  JAN 2023

What is the maximum number of hosts under class B addresses?

b. 65534 Class B Networks (/16 Prefixes) : This network is a 16-bit network prefix; its highest bit order is set to 1-0. It is a 14-bit network number with a 16-bit host number. This class B defines 16,384 (2 to the power 14) /16 networks, and supports a maximum of 65,534 (2 to the power 16 -2) hosts per network. Class B /16 block address is (1,073,741,824) = 2 to the power 30; therefore it represent 25% of the total IPV4.

What is the maximum number of networks possible in class C IP addresses?

c. 2^21 This class defines a maximum of 2,097,152 (2 ^21 ) /24 networks. And each network supports up to 254 (2^8 -2) hosts.

Suppose computers P and Q have IP addresses 10.20.5.25 and 10.20.5.9, respectively, and they both use the same netmask N. Which of the values of N given below should not be used if P and Q should belong to the same network?

d. 255.255.255.240 To determine which netmask should not be used, we need to find out the network address of P and Q using each of the netmasks provided and then check whether they belong to the same network or not. The network address of an IP address can be obtained by performing a bitwise AND operation between the IP address and the netmask. Using the given IP addresses of P and Q, and the first netmask, we get: P: 10.20.5.25 = 00001010.00010100.00000101.00011001 Q: 10.20.5.9 = 00001010.00010100.00000101.00001001 Netmask: 255.255.255.128 = 11111111.11111111.11111111.10000000 Performing a bitwise AND operation between each IP address and the netmask, we get: P network address: 00001010.00010100.00000101.00000000 = 10.20.5.0 Q network address: 00001010.00010100.00000101.00000000 = 10.20.5.0 Since both P and Q have the same network address using the first netmask, they belong to the same network. We repeat this process for the remaining netmasks: Using the second netmask, we get: Netmask: 255.255.255.192 = 11111111.11111111.11111111.11000000 P network address: 00001010.00010100.00000101.00000000 = 10.20.5.0 Q network address: 00001010.00010100.00000101.00000000 = 10.20.5.0 Again, both P and Q have the same network address using the second netmask, so they belong to the same network. Using the third netmask, we get: Netmask: 255.255.255.224 = 11111111.11111111.11111111.11100000 P network address: 00001010.00010100.00000101.00000000 = 10.20.5.0 Q network address: 00001010.00010100.00000101.00000000 = 10.20.5.0 Once again, both P and Q have the same network address using the third netmask, so they belong to the same network. Using the fourth netmask, we get: Netmask: 255.255.255.240 = 11111111.11111111.11111111.11110000 P network address: 00001010.00010100.00000101.00010000 = 10.20.5.16 Q network address: 00001010.00010100.00000101.00001000 = 10.20.5.8 Using the fourth netmask, P and Q have different network addresses, so they do not belong to the same network. Therefore, the netmask that should not be used if P and Q should belong to the same network is 255.255.255.240.

What is supernetting?

b. Combine multiple small networks in a single large network.

Which of the following is/are not a valid IPv6 address?

d. FE80:2030:31:24

Which is true for class E?

b. It is reserved for experimental purposes

What is the possible ip address range for class B?

c. from 128.0.0.0 to 191.255.255.255

You need 500 subnets, each with about 100 usable host addresses per subnet. What network mask will you assign using a class B network address?

b. 255.255.255.128

The header length of the ipv6 datagram is

d. 40 bytes

We write the IP address as 191.180.83.235/12 in CIDR notation. What is the subnet mask?

a. 255.240.0.0 To determine the subnet mask from an IP address in CIDR notation, we need to determine the number of bits in the network portion of the address. The IP address 191.180.83.235/12 indicates that the first 12 bits of the address represent the network portion, and the remaining 20 bits represent the host portion. To find the subnet mask, we need to set all the bits in the network portion to 1 and all the bits in the host portion to 0. Starting with the leftmost bit of the network portion, we have: 11111111 11110000 00000000 00000000 Converting this to dotted decimal notation gives: 255.240.0.0 Therefore, the subnet mask for the IP address 191.180.83.235/12 is (a) 255.240.0.0.

Important Notice:No CHANGE in NPTEL Exam Schedule for April 2024

Dear Student,

We wanted to take a moment to address an important matter regarding the upcoming election dates and their potential impact on your exam schedule.

  • None of the election dates clash with scheduled exam dates. If we schedule additional dates, we will ensure they again do not clash with elections in your state. 
  • Hence this is to confirm that there will be no changes to the exam dates and they are the same as previously scheduled. We may have exams in some cities on April 19 and April 26 depending on seat availability on scheduled dates. But again this will be done ensuring we don't conduct exams on election dates in your state. 
  • Your academic progress and success remain our top priority, and we are committed to maintaining the integrity of the examination process.
  • We have more than 6 lakh learners registered for April exams and logistics has been a huge challenge. We understand that some of you may need to travel to your native cities to participate in the voting process. Please remember that you selected your exam cities during registration, and it is crucial that you return to these cities to take your exams as scheduled. Since hall ticket and center allocation is under process, exam cities selected by you during exam registration cannot be changed now. 

Hence we kindly request that you make the necessary arrangements to ensure you can both exercise your right to vote and fulfill your academic obligations.

Warm Regards,

NPTEL Team.

Potential additional date (April 28th) for the April 2023 NPTEL exams

***THIS IS APPLICABLE ONLY FOR EXAM REGISTERED CANDIDATES*** Dear Student, Greetings from NPTEL! The Jan 2023 session is coming to an end soon and it’s time to put all your best efforts for the certification exam. The NPTEL team has always been there to make your learning process a joyful one and we hope that with your support we will be able to overcome the challenges of conducting a nation-wide exam of this magnitude. With the closure of exam registration form for the NPTEL April 2023 exams, the final registration count stands at 5.1 Lakh compared to 3.7 Lakh reported during the Jul-Dec 2022 semester. Based on the previous semester data, seats at the certification exam centres are booked by NPTEL at the beginning of the exam registration process. As the semester progresses, sometimes these numbers exceed our estimate, especially on certain dates and certain exam cities. Our goal is to allocate the chosen exam cities to all our learners. And by and large, we are able to allocate the chosen cities and dates with active support from our exam partner and our partner colleges. All efforts are being made to allocate the city of choice or the next nearest exam city for the April 29th/30th 2023 exams, as scheduled. However, in view of the unexpectedly large volume of exam registrations & limitation of seats at certain cities on a particular date, we may be compelled to shift the exam date of certain candidates to 28th April 2023 (Friday) as a last resort, only after exhausting all possibilities. We hope that you will appreciate our logistical constraints of such rescheduling and extend all necessary support as before and participate in the exam. With best wishes for the forthcoming exam(s), Warm regards, NPTEL Team
