What is the difference between PowerDNS recursor and authoritative?

Authoritative Nameservers are DNS Servers that contain the DNS records for your domains. The authoritative nameserver will answer queries with information directly from its records. Recursor DNS servers (commonly referred to as Recursive or Resolving) function between the end user and the authoritative DNS server.

Does PowerDNS use BIND?

Whatever the reason, PowerDNS has an easy way for you to use your existing BIND master zone configuration files to configure your PowerDNS server.

How do I add a master zone in Poweradmin?

Log in to Poweradmin on your master server by visitng http:// 111.111. 111.111 /poweradmin/ in your browser. Log in with the admin credentials you set earlier. Click the Add master zone link to create a new zone file.

Is recursive DNS better?

Recursive DNS queries generally tend to resolve faster than iterative queries. This is due to caching. A recursive DNS server caches the final answer to every query it performs and saves that final answer for a certain amount of time (known as the Time-To-Live).

What is the difference between PowerDNS and BIND DNS?

PowerDNS uses the pdns_control utility to control the nameserver functions, while BIND/named uses rndc to administer these functions. PowerDNS does not provide a recursive/caching nameserver and thus requires external nameservers in the resolv. conf file, while BIND/named does provide a recursive/caching nameserver.

Is BIND the best DNS server?

Advantages of BIND

BIND enjoys several important advantages, which make it by far the most popular DNS server on the Internet: Broad usage and strong community - BIND is a de facto standard for DNS in Linux systems, and is actively supported by a large open source community.

Is BIND still used?

BIND (Berkeley Internet Name Domain) is an open source solution for DNS which is still commonly used to manage network infrastructure on enterprises around the world.

What is a master DNS zone?

Primary DNS zone. Primary (Master) zones, contain a read/write copy of the zone data. There could be only one Master zone on one DNS server at a time. All the DNS records added manually or automatically, are written in this Primary zone of the DNS server. The data is stored in a standard text file – .

How do you create a zone in AD?

Locate the server where you want to add a zone, and right-click the server. Click Create DNS zone. The Create DNS Zone dialog box opens. In General Properties, select a zone category, a zone type , and enter a name in Zone name.

What is PowerDNS Recursor?

The PowerDNS Recursor is a high-performance DNS recursor with built-in scripting capabilities. It is known to power the resolving needs of over 150 million internet connections. The documentation is only for the 4.1 and higher series, users of older versions are urged to read End of life statements and upgrade!

What is the purpose of authoritative name servers?

Authoritative DNS nameservers are responsible for providing answers to recursive DNS nameservers about where specific websites can be found. These answers contain important information for each domain, like IP addresses.

What happens if I disable DNS recursion?

DNS recursion mean DNS will not query any other DNS server apart from its own cache or information available within its local DNS server. If you disable recursion in DNS, then your local DNS server might not resolve queries send to the external websites or the website it has no information in its server or cache.

Who is authoritative name server?

An authoritative server is the authority for its zone. It queries and is queried by other name servers in the DNS. The data it receives in response from other name servers is cached. Authoritative servers are not authoritative for cached data.

What is the difference between BIND and PowerDNS?

PowerDNS uses the pdns_control utility to control the nameserver functions, while BIND/named uses rndc to administer these functions. PowerDNS does not provide a recursive/caching nameserver and thus requires external nameservers in the resolv. conf file, while BIND/named does provide a recursive/caching nameserver.

What is the default TTL for PowerDNS?

The default time to live is 20 seconds and can be changed by setting cache-ttl .

How does DNS iterative work?

An iterative DNS query responds directly to the client with an address for another DNS server. The client queries each DNS server in an iterative manner until one of them finds and fetches the correct IP address for the requested domain.
