Lab 1 1: Network Connectivity Testing - jude-lindale/Wiki GitHub Wiki

##Summary In this lab I had the task of running commands in Command Prompt. The purpose was to start to understand how to find information related to the computers connected and what it means.

##Part 1

ipconfig

1. IPv4 Address: 184.171.157.49
2. Subnet Mask: 255.255.255.0
3. Default Gateway: 184.171.157.250

ipconfig/all

1. Physical Address: E0-D4-E8-84-86-5E
2. DNS Servers: 216.93.145.253 216.93.145.247 Ping

##Part 2 tracert www.google.com Total Number of Hops: 9

**nslookup ** Actual name of www.youtube.com: youtube-ui.l.google.com Number of IP addresses assigned to www.youtube.com: 19

Actual name for www.champlain.edu: ns.champlain.edu www.champlain.edu Number of IP addresses assigned to www.champlain.edu: 2

Tech Journal Lab Questions

Ipconfig; This command provides all current TCP/IP network configuration value, refreshes Dynamic Host Configuration Protocol (DHCP), and Domain Name System (DSN). When used without any parameters the command displays IPv4 and IPv6 addresses, subnet mask, and default gateway for all adapters. We can use this command to have fast access to view IPv4 and IPv6 addresses, subnet mask, and default gateway for all adapters in addition to the TCP/IP network configuration value, DHCP, DSN

Ping: The command provides verification for IP connectivity to other TCP/IP by sending Internet Control Message Protocol (ICMP) echo Request messages and displays the receipt of corresponding echo Reply messages alongside the amount of time it took to send the request and receive the receipt. This command can be used to troubleshoot connectivity, reachability, and name resolution. It can also be used to test both the computer name and the IP address of the computer.

Tracert: The command provides the path by sending the first echo Request message with a TTL of 1 and incrementing the TTL by 1 on each subsequent transmission until the target responds or the maximum number of hops is reached. This command can be used to figure out how many hops are taken to get to the desired destination.

Nslookup: The command provides information about the impute Domain Name System (DNS) and the number of IP addresses that are assigned to any given link. It can be used to find the true name of DNS of a link and the number of IP addresses that are assigned to said link.

Document how you open a command prompt on Windows.

1. Click on the magnifying glass on the bottom left of the toolbar
2. In the search bar type CMD and press enter or click on the Command Prompt application when you see it
