Understanding DNS Services
Learning Objectives:
•
Observe DNS record types and functionality
Topology Diagram
If you spend any time on the Internet sending e-mail or browsing the Web, then you use domain name servers without even
realizing it. Domain Name System (DNS) is used to translates domain names meaningful to humans into the numerical
identifiers (IP addresses) associated with networking equipment for the purpose of locating and addressing these devices
worldwide. An often-used analogy to explain the DNS is that it serves as the "phone book" for the Internet by translating
human-friendly computer hostnames into IP addresses.
Task 1: Observe DNS Records
Step 1. Test urls from a web browser.
1. Go to the Branch area of the topology.
2. Select Branch PC 1 and click on the Desktop tab. Then select the Web Browser. Type the URL
www.academy.com to view default webpage for the www.academy.com webserver.

3. Close and reopen the web browser and type ns.academy.com (without the www) into the web browser.
4. Close and reopen the web browser. Type academy.com into the web browser. That entry will not produce a
web page.
Step 2. View DNS Records.
1.
2.
3.
4.
Go to the Headquarters Campus Network.
Write down the ip address of the ns.academy.com server. ________________
Write down the ip address of the www.academy.com server. ________________
Select the ns.academy.com DNS server located in the Headquarter Campus Network and click on the Config
tab. Then select DNS from the list of Services and examine the DNS records.
5. Notice that there are different types of DNS records.The DNS records in this activity maps the names to an IP
address (type = A record).
6. Let’s create an alias that maps to another name (type = CNAME). Map www.ns.academy.com to
ns.academy.com. (See graphic below.) Click on Add.
7. When finished, go back to the Branch PC 1 and try the new DNS entry.
8. Go back to the ns.academy.com server. Look at the entry for academy.com. Use the Internet. What does SOA
stand for? ___________________
The URL ns.academy.com is translated into the IP address 192.0.2.68, which is the IP address of the Internal DNS. Next,
look at the other URL, www.ns.academy.com . It is translated into the URL ns.academy.com. The URL
www.ns.academy.com was created as a CNAME type (Canonical name record), which basically serves as an alias. So, as
was illustrated, ultimately, both URLs will be translated into the same IP address.

Step 3. View DNS records from another DNS server.
1. Select Branch PC 1 and click on the Desktop tab. Then select the Web Browser. Type the URL
www.isp.com to view default webpage for the isp.com webserver.
2. Go to the ISP Data Center.
3. Select the ns.isp.com DNS server and click on the Config tab. Choose the DNS service and add an entry into
the database to redirect the URL www.ispdata.com to www.isp.com. Use the information shown below to
create the new entry. Click Add when finished.
a) Name = www.ispdata.com
b) Type = CNAME
c) Host = www.isp.com
4. Type the URL www.ispdata.com to view default webpage for the www.isp.com webserver. The page should
be displayed this time.
Step 4. Observe DNS information using the nslookup command.
1. Select the Branch PC 1 and click on the Desktop tab. Then select the Command Prompt. Type the command
nslookup www.academy.com. Observe the output received.
PC>nslookup www.academy.com
Server: [192.0.2.68]
Address: 192.0.2.68
Non-authoritative answer:
Name: www.academy.com
Address: 192.0.2.69
2. Type the command nslookup academy.com from Branch PC1 Command Prompt. Observe the output
received.
PC>nslookup ns.academy.com
Server: [192.0.2.68]
Address: 192.0.2.68
Non-authoritative answer:
© 2011 Cisco and/or its affiliates. All rights reserved. This document is Cisco Public Information. Page 3 of 23
Name: ns.academy.com
Address: 192.0.2.68
Do you see any differences in the output between the two URLs? __________________________________________
What is different in the two outputs? _________________________________________________________________
______________________________________________________________________________________________
Step 5. Defining DNS record type available in this activity.
1. Select the ns.academy.com DNS server and click on the Config tab. Choose the DNS service. List the
different type of DNS entries that are available in this activity. Search the Internet and give a brief definition of
each record type.
