Instructions for Windows PC
Do not use google.com for any lab question, as this domain is used to provide examples. Your computer will need to be connected to the internet to complete the lab.

Bring up the command prompt (search > cmd). Type the command ‘hostname’ (do not use quotes). Answer the following question:
What is the name of your computer?
An IP address is a unique address to identify your computer on a network. A computer may have many IP addresses for each adapter that it uses to connect to the network, for example, an IP address for a wired connection and another IP address for a wireless connection. Your IP address may change, but your hardware address (MAC address) is permanent and does not change. Network administrators use a device’s MAC address to identify it on the network and then assign an IP address to that device.
What are the first three octets of your IPv4 address (i.e. 155.28.3.x)?
What is the physical address of that adapter (MAC address)?
An IP address may be private, which means that it is assigned locally. Or, your IP address may be public, which means that it is reserved globally (unique worldwide). We will find out if your IP address is public or private.
Is this the same address as the one you identified in step 2?
What are the first three octets of your public address (i.e. 155.28.3.x)?
Your public IP address is the one that systems and websites you connect to see and send requested data to.
How close to your actual location does this search return?
You may have trouble connecting to a website or information system. One quick way to check whether that site or system is reachable is through the use of the ping command. The ping command basically asks “Are you there?” several times, and the system simply responds with a “Yes” if it hears the request.
What domain did you use?
What was the IP address where the response came from?
How long did each reply take to return to your computer?
When you request data over the internet, your request is routed through several nodes (takes several “hops”) until it reaches its destination. A request to a particular system does not always take the same path through the internet. If a single path on the internet goes down, your request is simply rerouted through a different path. This feature makes the internet extremely reliable and redundant.
How many hops did your request take to the destination?
What locations can you identify along the route? (any city name abbreviations?)
Using IP void (as in step 4), where is the server located?
Domain names like google.com need to be registered with ICANN in order for them to be listed by DNS servers on the internet. Domain names expire if they are not renewed by the owner, and in 2015, a man purchased google.com for $12. (The purchase was cancelled one minute later, but Google has confirmed that he did own the domain briefly)
When was each domain registered?
When does each domain expire?
At the command prompt, type ‘ipconfig’ (advanced users may use ‘ipconfig /all’). Then, find the adapter that you use to connect to the internet; it may be a wired Ethernet adapter or wireless LAN adapter. For that adapter, answer the following questions:

Open a web browser and navigate to google.com. In the search bar, Google the phrase “My public IP”. Your search should return an IP address.

Copy your public IP address from step 3. In your web browser, navigate to the following url: https://www.ipvoid.com/ip-to-google-maps/ Then, paste your public IP address in the search bar.

Choose a domain for a website that you visit (for example, google.com). At the command prompt, type ‘ping google.com’. Remember, use something other than Google. Systems can be configured not to respond to ping requests, so if you’re not successful, try another.

You can trace the route your request takes through the internet by using the tracert (pronounced “Trace Route”) command. Use the same domain you used for the ping command in step 5. At the command prompt, type ‘tracert google.com’

You can find out who owns a domain name, when it was registered, and when it expires through ICANN and other whois lookup tools. In a web browser, go to https://lookup.icann.org/lookup and search for three different .com domains.
