Network Ping Analysis: Website Traffic, DNS, and ICMP Protocols

This assignment provides an analysis of network traffic using the ping command for websites like eBay, Yahoo, and YouTube. It explains how ping works by utilizing the ICMP protocol to check if an IP address is alive and to measure round trip times, loss rates, and other performance metrics. The assignment details the processes involved in DNS requests, ARP, and RARP protocols, which are crucial for converting hostnames to IP addresses and mapping IP addresses to MAC addresses. Furthermore, it explores the routing of network packets, the role of switches, and potential issues like network congestion and packet loss. The analysis includes a table showing the round trip times and distances for the mentioned websites. This document aims to provide a comprehensive overview of network communication and website performance analysis.

Task 3
Ping:www.ebay.com
This direction is utilized by the system Admin to check whether the specific IP is alive or not,
ping works by sending a 32 byte information to the IP address through ICMP convention.
Therefore, the Host is alive, at that point the information sent utilizing ICMP is gotten back,
and this likewise demonstrates whether there are any loss of information, its misfortune rate
and other valuable data.
When utilizing ping on the off chance that you determine the host name (www.ebay.com)
rather than IP address a DNS demand is made and the relating IP address of the host is
recovered by the framework then the ping utility uses the IP to send ICMP demand. So DNS
Request changes over the (intelligible) have name to IP address.
This is the curtailed type of Address Resolution Protocol. This has a table that comprise of all
the rundown of IP address and their relating MAC address (this location is the physical
location of your NIC) every one of the information goes to your IP address are gotten by the
NIC and prepared in like manner. On the off chance that you realize the IP address of the
framework and not about its MAC address then the framework utilizes ARP demand for
getting their MAC address. In the event of the other way around of the above situation RARP
is utilized.
These are only the traffic controllers of web situation. They help the approaching bundle to
arrive at their goal, in light of the goal address every parcel is coordinated to various courses.
At some point when there is an overwhelming burden in the course then the switch hinders all
the approaching solicitation till the heap diminishes and afterward start directing them again
at times the parcels are dropped this prompted loss of information.

Ping:www.yahoo.com
1. Your PC questions the DNS server customized on your PC for the IP of www.yahoo.com.
2. Your PC assembles the ICMP parcel with its IP as the source address and the IP for
www.yahoo.com as the goal.
3. Your PC will check the IP for the goal and check it against its course table. It will most
likely not discover a match, wherein case it is sent to the default door, normally the switch for
your system.
4. Next it verifies whether it realizes the MAC address of the default entryway. If not, it
utilizes ARP to outline MAC address to the IP address it has.
5. The parcel is sent to the default portal. In the event that you are running a NAT switch, the
IP header data is recorded in a table, at that point the source IP is changed to the open IP
address alloted by your ISP.
6. The switch checks its course table to check whether it realizes where to send the bundle. It
most likely simply has a default portal also. Return to stage 4. This happens on every switch,
however in the wake of getting to your ISP's system the switches most likely know the
courses to the IP of www.yahoo.com, and advances the bundles dependent on those courses.
7. Expecting the bundle hit no firewalls en route keeping it from arriving at its goal, it lands
at the machine with the IP address found in stage 1. This PC strips away the system data until
it gets to the ICMP part. It sees it is an ICMP reverberation bundle (ping), so it makes an
ICMP reverberation answer (pong) parcel, and the procedure begins once again until it
returns to your switch. This time its IP is the wellspring of the parcel and your open IP is the
goal.
8. The switch coordinates the bundle in the NAT table. It expelled the open IP from the goal
address and places your PC's nearby IP in its place.
9. Your PC gets the ICMP bundle.

Ping:www.youtube.com
In the same way as other mainstream sites, YouTube! Utilizes various servers to deal with
approaching solicitations to its site at www.youtube.com. The IP tends to that let you arrive at
the site may rely upon your physical area.
In the event that you are experiencing difficulty arriving at YouTube! Site through your
internet browser, you should realize the IP address of the site to have a go at getting entrance
that way.
Your absence of access may be because of an issue with your internet browser or antivirus
program that is blocking you from getting to YouTube!, the DNS reserve may be adulterated
and is preventing you from stacking the webpage through its URL, or the site may really be
down.
The table below shows the URL in which the IP address is being looked for and the time
allocated in order to reach the website destination to and back. It describes the traffic in
the web servers
Hostname Round TrIP Time Distance (km)
www.ebay.com Average = 198ms 13,302.10 km
www.yahoo.com Average = 179ms 8,218.28 km
www.youtube.com Average = 38ms 16,365.56 km
The graph shows the relationship the round trip time the message is transferred to the site
destination in the network traffic. The time taken to and the response time by the system.
