the address class/purpose of following addresses:
- 128.211.6.115

of an Internet addressing? Explain the addressing scheme with respect of
Internet hosts and networks. [5]

4.
b) Subnet
the class C network address 198.69.25.0 into eight subnets. [6]
5.
a) One function of a routing protocol is
to determine the 'best path' between the sending and the receiving nodes. What
is considered as 'best path'?
[6]
b) OSPF is considered to be a distributed
routing protocol since routers periodically exchange information with each of
their neighbours. Is it possible to have routing protocol that is centralized
in nature? How do you think centralized routing protocol would work? Will there
be some inherent problems?
[6]
6.
b) 'DHCP' permits completely automated
address assignment'. Justify the statement. [4]
July-2005 [20]

explain in detail any three of the following acronyms:

5.
a) Giving suitable examples explain three
kinds of classes of an Internet addressing, with special emphasis on the range
spanned by each class? [9]
7.
c) Why
does BGP not exchange routing information periodically as RIP does? [5]

is IP Host address? Discuss in detail.

January-2007 [34]
1.
a) How
do we reuse IP address using Network Address Translation (NAT) mechanism? [4]
b) What
is 127.0.0.1? Explain with example. [4]

is the difference between a packet and a frame? [4]
d) What
is MAC Address Filtering? [4]
3.
a) What
are routing protocols? Compare and contrast different types of protocol.
[6]
c) Why is Open Shortest Path First (OSPF)
protocol required? What kinds of connections does it support? [6]
7.
a) Explain the Reverse Address Resolution
Protocol (RARP). Why is it required? [6]
July-2007 [14]
1.
a) How
did CIDR ease the problem of fast depleting Ipv4 addressing? [4]
b) What
are some important features of DHCP?
[4]

protocol required? What kind of connections does it support? [6]
January-2008 [24]
2.
a) How IP addresses are classified? What
is the use of classifying IP addresses? What is the possible range of IP
addresses for the different classes?
[6]
7.
a) Write at least three problems
associated with Ipv4 addressing. What are some of the solutions that have been
proposed to overcome these problems? [6]
b) What is ARP cache? What is the normal
expiration time of an entry in ARP cache? Why does ARP request message carry
the IP address and the link layer address of the sender?
[6]
c) What is the difference in the subnet
mask for a Class A address with 16 bits for the subnet ID and a class B address
with 8 bits for the subnet ID? Is the subnet mask 255.255.0.255 valid for a
Class A address?
[6]

1.
e) What
is IP address? Why is it needed? What is the difference between Public and
Private IP Addresses? [4]
2.
b) What
do you understand by Internet Protocols? Which body does have control on them?
List any four Internet Protocols along with their basic functions. [6]
3.
a) Write the salient features of the
following basic network utilities:
i) IPConfig
ii) Ping
iii) Traceroute [6]
4.
a) What is
the network prefix of IP address 192.110.50.3/24? Explain the difference
between a network IP and a network prefix. [6]
b) A network contains two routed subnets:
Subnet A and Subnet B. Subnet B contains a
Windows 2000 server configured as a DHCP server. This server
has scopes created for
both Subnet A and Subnet B. Subnet A does not contain DHCP
server.
The clients on Subnet A are not receiving IP addresses from
the DHCP server. What is
done to enable clients in Subnet A to receive dynamically
assigned IP addresses?
Choose all that apply. [6]
6.
a) Choose any two scenarios from the
following in which BGP is recommended.
i) You need a default route to connect to a single ISP.
ii) When you need to connect to two or more ISPs.
iii) When you are sending traffic through one AS to get to
another AS.
iv) When you need a simple routing on your intranet. [6]

c) When is an ARP request packet
generated? Describe the various steps that take places when a host receives an
ARP request packet? [6]
4.
c) A company XYZ has five departments. The
company wants to assign a single class B address 167.172.0.0 to its five
departments. It wants five different subnets to be created with each subnet
having 25 host addresses. Show the steps involved to achieve the above. [6]
