211.215.201.18 (iii) 171.185.112.115
8.
For the
following addresses, find the class, the block and the range of addresses:
(i)
15.1.1.1 (ii) 175.56.1.1 (iii) 221.120.74.1
9.

115.375.79.85 (ii) 295.91.79.15 (iii) 60.74.155.266
10. (a) Find the class of the following IP addresses, and
give explanation for it:

00011011 11111111
(ii)
00101001
00001011 00001011 11101111
(iii)
10010001 00101011 00001011 11101111
(b) One of
the address in a block is 201.12.8.45.Find the number of addresses, the first
address and the last address.
11. A host with IP address 192.25.42.20 and physical
address 0xb2efc5f7fe2c has a packet to
send to another host with 165.125.42.29 and physical address 0xf456e73f227c.
The two hosts are on the same Ethernet. Construct ARP request and reply
packets.
12. Draw and explain the fields of an IP datagram. An IP
packet has arrived with the first 8 bits as shown:
ç 01100011
The receiver discards the packet. Why?
13. (a) In an IP
packet, the value of HLEN is 7 (decimal) and the value of the total length
field is 55 (decimal). How many bytes of data are being carried by this packet?
(b) In an
IP packet, the value of HLEN is 0C (hex) and the value of the total length
field is 0AFF (hex). How many bytes of data are being carried by this packet?
14. Calculate the checksum for the following IP datagram

15. An IP packet has arrived with the hexadecimal digits
as shown below:
ç 450000380d3a00000201bb6ec0a802034a7de2f4
How many
hops can this packet travel before being dropped, The data belong to what upper
layer protocol, What is identification value, what is the value for checksum,
what is source and destination address?
16. What is the significance of identification, flags, and
offset fields of IP datagram? A datagram of size 7520 bytes is transmitted on a
network of MTU 1100 bytes. Calculate the offset values and range of data bytes
present in each fragments. What is the status of flags bit in each fragment?
Additional
Questions for practice
17. What
services are provided by network-level of internet? Discuss in detail.
18. Draw and explain different fields of Ethernet frame.
19. Compare connection-oriented and connectionless
delivery systems.
20. Enlist the advantages and drawbacks of
packet-switching networks.
21. What are the advantages of circuit-switching networks
over packet-switching? Why?
22. What connecting devices are used at layer-1, layer-2,
and layer-3 in internet? Explain their characteristics and functions.
23. What addresses are used at layer-1, layer-2, and
layer-3 in internet? Explain briefly.
24. Explain the application programs at your site that use
TCP/IP.
25. What is Ethernet address? What are its properties?
26. What is an IP address? What are the desirable
properties of IP address? What is signified by prefix and suffix of IP address?
27. Explain classful addressing in TCP/IP.
28. Draw and explain ARP and RARP protocol format.
29. Explain the concept of (i) datagram encapsulation,
(ii) network MTU, (iii) and multiplexing at IP and TCP layers.

field? Explain briefly. An IP packet has the value of HLEN as 1011 in binary.
How many bytes of options are being carried by this packet?
34. Draw
the architecture of Internet. Explain its components.
