1. New laptop computers are being introduced for some of the managers in A. Datum Corporation. You need to test how the IPv4 configuration will behave when the managers are away from the office and a DHCP server is unavailable. Objectives Modify the IPv4 settings for a LAN connection. Configure a LAN connection to use DHCP.

For this lab, you will use the available virtual machine environment. Before you begin the lab, you must
complete the following steps:

1. On the host computer, click Start, point to Administrative Tools, and then click Hyper-V Manager.
2. In Hyper-V® Manager, click 20687A-LON-DC1, and in the Actions pane, click Start.
3. In the Actions pane, click Connect. Wait until the virtual machine starts.
4. Log on using the following credentials:
 
   o User name: Adatum\Administrator
   o Password: Pa$$w0rd
5. Repeat steps 2-4 for 20687A-LON-CL1.

Enabling Automatic IPv4 Configuration

The main tasks for this exercise are as follows:
1. Verify the current IPv4 configuration.
2. Configure the computer to obtain an IPv4 address automatically.
3. Verify the new IPv4 configuration.

Task 1: Verify the current IPv4 configuration
1. Log on to LON-CL1 virtual machine as Adatum\Administrator with the password Pa$$w0rd.
2. Open a command prompt, and then run the command IPConfig /all.

   o What is the current IPv4 address?
   o What is the subnet mask?
   o To which IPv4 network does this host belong?
   o Is DHCP enabled?

Task 2: Configure the computer to obtain an IPv4 address automatically
1. Use Network and Sharing Center to view the properties of Local Area Connection.
2. Modify TCP/IPv4 to:

   o Obtain an IP address automatically.
   o Obtain a DNS server address automatically.

Task 3: Verify the new IPv4 configuration
• In the Local Area Connection Status window, view the Details.
  o What is the current IPv4 address?
  o What is the subnet mask?
  o To which IPv4 network does this host belong?
  o Is DHCP enabled?
  o When does the DHCP lease expire?

Results: After this exercise, you will have configured LON-CL1 to obtain an IPv4 configuration
automatically from a DHCP server.

Configuring IPv4 Manually
The main tasks for this exercise are as follows:
1. Deactivate the DHCP scope.
2. Obtain a new IPv4 address.
3. Configure an alternate IPv4 address.
4. Configure a static IPv4 address.

Task 1: Deactivate the DHCP scope
1. Log on to LON-DC1 virtual machine as Adatum\Administrator with the password Pa$$w0rd.
2. Use the DHCP Administrative Tool to deactivate the IPv4 scope named A Datum Scope.

Task 2: Obtain a new IPv4 address
1. On LON-CL1, at the command prompt, run the command IPConfig /release.
2. Run the command IPConfig /renew.
3. Run the command IPConfig /all.
   o What is the current IPv4 address?
   o What is the subnet mask?
   o To which IPv4 network does this host belong?
   o What kind of address is this?
 
Task 3: Configure an alternate IPv4 address
1. In the properties for TCP/IPv4 for Local Area Connection, use the Alternate Configuration tab to
   configure the following:
   o IP address: 172.16.16.10
   o Subnet mask: 255.255.0.0
   o Preferred DNS server: 172.16.0.10
   o Do not validate settings
2. At the command prompt, run the following commands:
   o IPConfig /release
   o IPConfig /renew
   o IPConfig /all
   o What is the current IPv4 address?
   o What is the subnet mask?
   o To which IPv4 network does this host belong?
   o What kind of address is this?

Task 4: Configure a static IPv4 address
1. In the Local Area Connection Status window, view the Properties.
2. In the properties for TCP/IPv4 for Local Area Connection, configure the following:
   o IP address: 172.16.16.10
   o Subnet mask: 255.255.0.0
   o Preferred DNS server: 172.16.0.10

Results: After this exercise, you will have tested various scenarios for dynamic IP address assignment, and
then configured a static IP address.
