Lab 1 1: Network Connectivity Testing (1.31.2021) - jude-lindale/Wiki GitHub Wiki

Summary

In this lab, I was task with running some Network commands in cmd. The commands used provided specific information about my network connectivity in general and to specific destinations.


Useful Commands/Instructions

  1. ipconfig
  2. ipconfig/all
  3. ping
  4. tracert: This command will report each router encountered between your workstation and whatever connection that is being made
  5. 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. This should leave you with a prompt of “>”.

Tech Journal Lab Questions

Record the following for the commands:

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
