==Purpose==
In this lab, you are going to build a primary name server for your assigned DNS domain using the BIND package on your VM1. A primary name server does not depend upon having access to other name servers in order to function.
Once you have your primary name server runningfor your forward and reverse zones, you will use command line DNS client tool(s) to test the correctness of the query responses from your Primary DNS server.
Then you will configure both zones to support dynamic updates. Dynamic DNS accepts updates from the command line utility “nsupdate”. This lab does not configure the DNS server to use secure channel for the updates.
# What are the steps using nsupdate to delete the “PTR” record created in question 6?
# What are the steps using nsupdate to delete the “CNAME” record created in question 7?
# What would happen if you try to delete a non-existence resource record (PTR, A, CNAME, MX, etc) from a dynamic DNS zone using nsupdate?13. # What would happen if you ry try to add a duplicate resource record to a dynamic zone using nsupdate?
