NETWORK LAB ASSIGNMENT1
Summary
The purpose of this report is to carry out packet capture of different websites through pinging
and tracing methods. The ping process involves communication with a website hosted in a
different continent. Since the trace route is conducted from Asia, www.inria.fr is chosen from
the European continent. Then the report conducts trace route of a website hosted in Europe
using the native trace route function of windows through command prompt. Thereafter the
website gaia.cs.umass.edu is traced using a more advanced tracing software called Pingplotter
for three different packet sizes 56, 2000 and 3500 bytes respectively. In all these activities,
the packets were captured with the help of the protocol analyser called Wireshark and the
ICMP packets get analysed in detail. Thereafter the lab report ends with observations in
concluding notes.

Introduction
The following report carries out packet capture of different websites through pinging
and tracing methods. The report begins by conducting the ping process which involves
communication with a website hosted in a different continent. Since the trace route is
conducted from Asia, www.inria.fr is chosen from the European continent. Then the report
conducts trace route of the same website from Europe using the native trace route function of
windows through command prompt. Thereafter the website gaia.cs.umass.edu is traced using
a more advanced tracing software called Pingplotter for three different packet sizes 56, 2000
and 3500 bytes respectively. In all these activities, the packets were captured with the help of
the protocol analyser called Wireshark and the ICMP packets get analysed in detail.
Thereafter the lab report ends with observations in concluding notes.

Research
1. ICMP and Ping: Website of different continent
Wireshark is launched and the recording of the Ethernet network is started.

NETWORK LAB ASSIGNMENT4
The ping is being made from Asia so a website from a different continent is used
which is www.inria.fr hosted on Europe in France.

NETWORK LAB ASSIGNMENT5
The pinging activity is recorded with wireshark which captures all the associated
communication packets.

NETWORK LAB ASSIGNMENT6
1. IP address of source and destination
Among the packets captured by wireshark the ICMP packets are shortlisted by
applying the filter for sorting ICMP packets and the first ICMP packet is selected.
The source IP address is identified to be 10.10.63.7 and the destination IP address is
found to be 128.93.162.84.

NETWORK LAB ASSIGNMENT7
2. Why ICMP packets do not have port numbers for source and destination
ICMP packets do not have port numbers for the source and destination because it is
designed for communicating with network layer information between the routers and hosts
instead of among processes of application layer.
3. Examination of ping request packets sent by host: ICMP type and code
number, other fields contained by the packet, checksum; sequence number;
identifier in bytes
