Objectives
Part 1: Configure Static IPv4
Addressing
Part 2: Configure and Verify DNS Records
Background
In this activity, you will configure and
verify static IP addressing and DHCP addressing. You will then configure a DNS
server to map IP addresses to the website names.
Note: Packet Tracer only simulates the process for configuring these
services. DHCP and DNS software packages each have their own unique
installation and configuration instructions.
Part 1: Configure Static IPv4 Addressing
Step 1: Configure the Inkjet printer with static IPv4 addressing.
The home office computers need to know
the printer’s IPv4 address to send information to it. The printer, therefore, must
use a static (unchanging) IPv4 address.
a.
Click Inkjet and click the Config
tab, which displays the Global Settings.
b.
Statically assign the Gateway address
as 192.168.0.1 and the DNS Server address
as 64.100.8.8.
c.
Click FastEthernet0 and statically assign the IP address as 192.168.0.2 and the Subnet Mask address
as 255.255.255.0.
d.
Close the Inkjet window.
Step 2:
Configure WRS to provide DHCP
services.
a.
Click WRS and click the GUI
tab, and maximize the window.
b.
The Basic Setup window
displays, by default. Configure the following settings in the Network Setup
section:
1)
Change the IP Address to 192.168.0.1.
2)
Set the Subnet Mask to 255.255.255.0.
3)
Enable the DHCP Server.
4)
Set the Static DNS 1 address to
64.100.8.8.
5)
Scroll to the bottom and click Save.
c.
Close the WRS window.
Step 3:
Request DHCP addressing for the
home laptop.
This activity focuses on the home office.
The clients that you will configure with DHCP are Home Laptop and Tablet.
a.
Click Home Laptop and click the Desktop
tab > IP Configuration.
b.
Click DHCP and wait until the DHCP request is successful.
c.
Home Laptop should now have a full IP configuration.
If not, return to Step 2 and verify your configurations on WRS.
d.
Close the IP Configuration
window and then close the Home Laptop window.
Step 4:
Request DHCP addressing for the
tablet.
a.
Click Tablet and click the Desktop
tab > IP Configuration.
b.
Click DHCP and wait until the DHCP request is successful.
c.
Tablet should now have a full IP configuration.
If not, return to Step 2 and verify your configurations on WRS.
Step 5:
Test access to websites.
a.
Close the IP Configuration window, and then click Web Browser.
b.
In the URL box, type 10.10.10.2 (for the CentralServer website) or 64.100.200.1 (for the BranchServer website) and click Go. Both websites should appear.
c.
Reopen the web browser. Test
the names for those same websites by entering centralserver.pt.pka and branchserver.pt.pka.
Click on Fast Forward Time on the
yellow bar below the topology to speed the process.
Part 2: Configure Records on the DNS Server
Step 1:
Configure famous.dns.pka with records
for CentralServer and BranchServer.
Typically, DNS records are registered
with companies, but for the purposes of this activity you control the famous.dns.pka server on the Internet.
a.
Click the Internet cloud. A new network displays.
b.
Click famous.dns.pka and click the Config
tab > DNS.
c.
Add the following resource
records:
Resource
Record Name
|
Address
|
centralserver.pt.pka
|
10.10.10.2
|
branchserver.pt.pka
|
64.100.200.1
|
d.
Close the famous.dns.pka window.
e.
Click Back to exit the Internet
cloud.
Step 2: Verify the ability of client computers to use DNS.
Now that you have configured DNS records,
Home Laptop and Tablet should be able to access the websites by using the names
instead of the IP addresses. First, check that the DNS client is working
properly and then verify access to the website.
a.
Click Home Laptop or Tablet.
b.
If the web browser is open, close it and select Command Prompt.
c.
Verify the IPv4 addressing by entering
the command ipconfig
/all. You should see the IP address for the DNS
server.
d.
Ping the DNS server at 64.100.8.8 to verify connectivity.
Note: The first two or
three pings may fail as Packet Tracer simulates all the various processes that
must occur for successful connectivity to a remote resource.
e.
Test the functionality of the
DNS server by entering the commands nslookup
centralserver.pt.pka and nslookup branchserver.pt.pka. You should get a name resolution showing the IP address for each.
f.
Close the Command Prompt window
and click Web Browser. Verify that Home Laptop or Tablet can now access the web pages for CentralServer and BranchServer.
