An authoritative name server is just what it sounds like: It is the original and conclusive source of DNS zone information for a particular domain.
Recall that it isn’t authoritative but simply provides query resolution to network client resolvers (client-side portion used to perform DNS queries) on your local machine. The supermaster feature set in Power DNS allows you to automate the provisioning of slaves.
Superslaves can configure themselves automatically as a slave for a zone when they receive notification from a known supermaster.
Power DNS Authoritative Server (My SQL Back End)Power DNS has many configuration options – so many, in fact, that someone could easily write an entire book on each.
Power DNS is an amazing, feature-rich and versatile DNS server solution.
Originally created by Power BV as a commercial product, it was later opened up and licensed under the GPL.
Today, it thrives with both commercial and community contributions, making it an outstanding DNS server alternative.DNS, of course, is the distributed, hierarchical naming system that allows us to map what would be IP addresses to much more humanly digestible addresses.Thankfully, we no longer live in the early days of the Arpanet (precursor to today’s Internet), where we had to transfer large host files from node to node.Its compact codebase and focus on security, scalability, and reliability make Power DNS (PDNS) a great nameserver choice; it is jam packed with features that would impress any network or sys admin (Table 1).PDNS Key Components Power DNS has two key distinct components: the authoritative server and the recursor.Other DNS servers combine these roles, but Power DNS holds them separate, and you can configure PDNS as either option.
