Checkpoint: DNS

For this checkpoint you will get your DNS server running and able to serve names to the Internet

The DNS server in Windows is a full featured DNS server that's capable of being the public face of your domain. For this checkpoint you will install DNS (and Active Directory) and set it up to serve records to the Internet

Give SVR-A a Static IP Address
Your SVR-A will need a static IP address to be the gateway for the rest of your network. You must give static IPv4 and IPv6 address to Ethernet0. The static IP address is derived from your private network number. You can find your private network number in VMware. The network number will be visible in the summary tab of both the web and RDP based interface. The pictures below show the locations in both interfaces. 

Your network number will be between 1 and 100. Set the IPv4 information on Ubuntu's eth0 as follows:
  • IPv4
    • Address: 172.20.196.X (Where X is your network number). 
    • Netmask: 
    • Gateway: 
    • Nameservers: and (you can use any valid nameserver)
  • IPv6
    • Address/Mask 2607:f380:80f:f830:196:X::1/64 (Where x is your network number)
    • Do not set the gateway!
Test your configuration using the following commands:

    ping -4 www.google.com
    ping -6 www.google.com

Give your server a hostname. It can be anything. 

Install Active Directory
Installing Active Directory will automatically install DNS and setup basic domain records. After Active Directory has installed promote SVR-A to a domain controller. This will require a reboot. Create a new forest using your custom domain name: 


After the reboot open the DNS console and note that DNS records have been created for your domain and your SVR-A based on the name you gave it. 

Create a CNAME record for a machine called router. Router should point to whatever you named your server. 

Test DNS
If you've done everything properly you can now use the nslookup program from home** to check to see if your domain is online. Execute the following command:

nslookup router.<mydomain>.cis.cabrillo.edu 

Be sure to replace <mydomain> with the name you gave me for your domain. Also, don't run nslookup on SVR-A, that will work even when your domain is not available on the Internet. 

** This will only work if you have IPv6 at home. If not you'll have to use nslookup from your VM.
