In this lab, we go over the Network utilities in PC

Please note down your answers on a piece of paper for the demo purposes at the conclusion of the lab.

Question $1$: IP Address of the PC

Turn on your Windows $7$ machine

Use Control Panel to check out the network settings

Note down the IP address, Gateway and Subnet Mask for your network card

Repeat the same process again but this time use the command prompt to check the IP Address, Subnet Mask and the Gateway

Question $2$: DHCP

Your computer gets its IP address from the austincc.edu$$s DHCP server. By using command prompt, you can force the PC to renegotiate a new IP$.$

Go to cmd

Type: ipconfig $/$release

View the IP address and Network Connectivity

Type: ipconfig $/$renew

Repeat $(3)$ : Note down your observations

Question $3$: Windows$10$ VM: Bridged vs$.$ NAT

Configure your VM Network Settings to be $$Bridged$$

Start your Windows $10$ VM

Go into the command prompt and find out its IP Address and Subnet Mask. Write them down

Change the Network Settings to $$NAT$$

Repeat $(3)$: Do you see any change of IPs? Explain why in the Demo.

Question $4$: Install Windows Virtual Network Loop Back Adapter in Win$10$ VM

Start Windows$10$ VM

IP address: $10\mathrm{.}10\mathrm{.}1\mathrm{.}1$

Subnet mask will populate on its own

You have configured a dummy network adapter that could be used to test the hardware of your network card

Ping the IP setup in $(11)$ in the command prompt

What do you see? Record your observations for the Demo

Question $5$: Address Resolution Protocol in Windows $7$ host machine
