00001011 11101011
ii)11001001 10010011
00011011 11111011
6.
Change the
following IP addresses from dotted-decimal notation to binary and hex notation.
(i)
110.56.45.80 (ii)
210.215.211.198 (iii) 71.165.101.12
7.
For the
following addresses, find the class, the block and the range of addresses:
(i)
11.1.1.1 (ii) 145.56.1.1 (iii) 216.120.74.1
8.
Find the error,
if any, in the following IP addresses:
(i)
115.075.79.85 (ii) 275.91.79.15 (iii)
260.074.155.261
9.
(a) Find the
class of the following IP addresses, and give explanation for it:
(i)
11000011 10000011
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.
10. Draw and explain the header of ARP/RARP protocol. A
host with IP address 155.25.42.20 and physical address 0xb2efc577f42c has a
packet to send to another host with 155.25.42.29 and physical address
0xe456173f227c. The two hosts are on the same Ethernet. Write the contents of
ARP request and reply packets.
11. Draw and explain the fields of an IP datagram. An IP
packet has arrived with the first 8 bits as shown:
ç 11100010
The receiver discards the packet. Why?
12. What are the different options for IP datagram option
field? Explain briefly. An IP packet has the value of HLEN as 1101 in binary.
How many bytes of options are being carried by this packet?
13. (a) In an IP packet, the value of HLEN is 5 (decimal)
and the value of the total length field is 45 (decimal). How many bytes of data
are being carried by this packet?
(b) In an
IP packet, the value of HLEN is 0A (hex) and the value of the total length
field is 0A2F (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 11520 bytes is transmitted on
a network of MTU 960 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. Enlist
and explain the properties of internet.
18. What
services are provided by network-level of internet? Discuss in detail.
19. Explain in detail application-level services of
internet.
20. Draw and explain different fields of Ethernet frame.
21. Compare connection-oriented and connectionless
delivery systems.
22. Enlist the advantages and drawbacks of
packet-switching networks.
23. What are the advantages of circuit-switching networks
over packet-switching? Why?
24. What connecting devices are used at layer-1, layer-2,
and layer-3 in internet? Explain their characteristics and functions.
25. What addresses are used at layer-1, layer-2, and
layer-3 in internet? Explain briefly.
