PowerDNS is a run on many Linux / DNS servers on Unix derivative version, it is possible to use different back-end configuration, including the type of BIND zone files, relational databases, or load balancing / failover algorithms. It can also be configured to a DNS recursive filter, as a separate process running on the server

11, add a new main area, just click "Add main area"
12, Add area "button to add the DNS zone.
You need to fill out a few things:
- Domain (Domain) - you want to add a domain area.
- Owner (Owner) - set the owner of a DNS zone.
- Template (Template) - DNS template - blank.
- DNSSEC - Domain Name System Security Extensions (optional - see if you need to).
13, edit existing DNS zone or add a new record
Add a new DNS entry here, you need to set the following information:
Name (Name) - the entry name. The first part simply add the domain / sub-domain, PowerAdmin will add the rest.
Type (Type) - select the record type.
Priority (Priority) - Record priority.
TTL - survival time, in seconds.
