#Maintaining DNS Records Now that you have a working internal DNS, you need to maintain your DNS records so they accurately reflect your server environment.

##Adding Host to DNS

Whenever you add a host to your environment (in the same datacenter), you will want to add it to DNS. Here is a list of steps that you need to take:

###Primary Nameserver

• Forward zone file: Add an "A" record for the new host, increment the value of "Serial"
• Reverse zone file: Add a "PTR" record for the new host, increment the value of "Serial"
