Week 9 Lab 1 : Exploring Network Tools - jwells24/Tech-Journal GitHub Wiki

SYS-140 - Week 9 Lab 1

Instructions: (Follow instructions carefully!)

Objective

For this assignment, you will be using the network tools to answer a couple of questions: What is the IP address of the champlain.edu web server? Where is the web server located?

Lab Preparation

Preparation:

Run the tools on your Windows 10 host computer. Submission will be via GitHub. Here is a video showing how to format the assignment. https://drive.google.com/file/d/1L6sBevYU__wJVNLnROO2U4AVRxc5Kvco/view

nslookup

Click on the magnifying glass in the Windows taskbar and type ‘cmd’. Open the Command Prompt application that pops up. The command nslookup is used to find the IP address of a host and the hostname for an IP address. Type into the command prompt window nslookup champlain.edu The IP address shown in the ‘Non-authoritative answer’ portion is Champlain’s web server next to “Addresses” Copy the output to your GitHub submission and put asterisks next to the IP Address(es).

 Server:  ns.champlain.edu
 **Address:  216.93.145.253**
 Name:    champlain.edu
**Address:  208.115.107.132**

Ping

Type ping x.x.x.x into your command prompt, replacing x.x.x.x with the Champlain.edu IP address you found in Part 1. Let the program run to completion. Copy the output to your GitHub submission and put asterisks next to the IP Address(es).

Pinging 208.115.107.132 with 32 bytes of data:
Reply from 208.115.107.132: bytes=32 time=78ms TTL=49

Ping statistics for 208.115.107.132:
    Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
    Minimum = 69ms, Maximum = 78ms, Average = 71ms

NOTE: By default, ping will send four packets (ICMP packets) and stop. If you need to run ping continuously on Windows, then run: ping -t x.x.x.x The -t will continuously run until you type Ctrl+c.

Part 3: Tracert (Where in the world in Champlain’s web server?)

Now, type tracert -d www.champlain.edu in your command prompt. The switch -d will not resolve hostnames so it runs faster. Let the program run to completion, and copy the output into your GitHub lab submission mentioned in class today Tracert shows you the path your network traffic takes from your machine to champlain.edu. Analyze the path that tracert returned (take note of the names/IPs returned from each hop in the route!)
