1. Study and test the functionality of basic networking commands in the laboratory.
A.) PING
i) What is the IP address of www.vit.ac.in?
→ [136.233.9.13]
ii) Check whether TCP/IP is properly installed and functioning in your system.
➔ YES TCP/IP IS PROPERLY INSTALLED IN MY PC AS , I AM GETTING PACKETS SEND AND RECIVED
PROPERLY .
iii) Indicate what percentage of packets sent resulted in a successful response. For the packets from
which you received a response, write down the minimum, average and maximum round trip times in
milliseconds.
➔ Packets: Sent = 4, Received = 4, Lost = 0 (0% loss), 100 % successful response.
➔ Minimum = 106ms, Maximum = 120ms, Average = 113ms
iv) Increase or Decrease the Time Interval between Packets. Write the response.

vii) For some of the hosts, you may not have received any responses for the packets you have sent.
What are the reasons for not getting a response?
FOR SOME HOST WE MAY NOT RECEIVE ANY RESPONSE DUE TO INAVAILABILITY(NOT ) OF THAT
HOST OR THAT HOST MAY NOT PRESENT.
FOR EXAMPLE:
C:\Users\yesag>PING www.20mis0151.ac.in
Ping request could not find host www.20mis0151.ac.in. Please check the name and try again.

E.) TRACEROUTE or TRACERT
State
PID
i) Write the function of this command
Traceroute is a network diagnostic tool used to track in real-time the pathway taken by a packet on
an IP network from source to destination, reporting the IP addresses of all the routers it pinged in
between. Traceroute also records the time taken for each hop the packet makes during its route to
the destination.
The tracert command is a Command Prompt command that's used to show several details about the
path that a packet takes from the computer or device you're on to whatever destination you specify.
F.) NSLOOKUP
i) What is the IP address and name of the machine www.google.com?

➔ The main difference between tracert and pathping is that tracert helps to find the actual
path from the source to the destination device while pathping is a command that provides
information about network latency and network loss at intermediate hops between the
source and the destination devices
