Lab 1.1 Networking Connectivity Testing - Hsanokklis/2022-2023-Tech-journal GitHub Wiki

Objectives: Test simple network connectivity using common command-line tools like ping, tracert, and nslookup. Introduce concepts of IP addresses and hostnames.

Network Discovery Lab Part 1

Search "windows defender firewall", click on turn on/off firewall, Turn off public and private network firewall

run command ipconfig

run command ipconfig /all

Ping the default gateway

default gateway: The router that connects the VM to the greater Champlain college network.

Ping www.google.com

Ping someone else

How are the results different then pinging Google?

It took more time to get the successful ping from Google then pinging someone on the same network.

Network Discovery Lab Part 2

In computer networks a diagnostic tool for displaying the route (path) and measuring transit delays of packets across an Internet Protocol (IP) network is traceroute. This is an effective, easy and simple command tool Network Administrators have at their disposal for quick and easy initial diagnosis of their networks.

Run tracert www.google.com

There are 14 hops between me and www.google.com

The router names are in the rightmost column(there are 14 of them, an example would be champlain.edu )

Run the command nslookup

This command line tool is used to querying the Domain Name System (DNS) to obtain domain name or IP address mapping or for any other specific DNS record

Run command nslookup and type bing.com There are 3 addresses assigned to bing.com

Run command nslookup and type www.champlain.edu

There is 1 address assigned to www.champlain.edu
