djbdnsДjbdns is a collection of DNS applications, including tinydns, which was the second most used free software DNS server in 2004. It loads the contents of /etc/hosts, so that local host names which do not appear in the global DNS can be resolved. It can serve the names of local machines which are not in the global DNS.Дnsmasq accepts DNS queries and either answers them from a small, local cache or forwards them to a real, recursive DNS server. DnsmasqДnsmasq is a lightweight, easy to configure DNS forwarder, designed to provide DNS (and optionally DHCP and TFTP) services to a small-scale network. Processing 17 million queries per second, it can eliminate dozens of DNS clusters and load balancers, dramatically decreasing the total cost of ownership and simplifying the DNS infrastructure. It delivers carrier grade DNS performance for ISPs and enterprises enhancing security with deep analyses transactions at the heart of the DNS recursor. DNS BlastДNS Blast is highly secure recursive DNS software from EfficientIP. It supports high rates of dynamic update.

Cisco Network RegistrarД¬NR includes a commercial DNS server from Cisco Systems usually used in conjunction with the CNR DHCP (Dynamic Host Configuration Protocol) server. The BIND 10 codebase continues on as an open source project at ( ibid.) It is not included in this comparison at this time. ISC cited a lack of resources to continue development of BIND 10, and they reaffirmed their commitment to BIND9. Its first release was in April 2010, but ISC involvement concluded with the release of BIND 10 version 1.2 in April 2014. Internet Systems Consortium started development of a new version, BIND 10. BIND9 is a ground-up rewrite of BIND featuring complete DNSSEC support in addition to other features and enhancements. BIND4 and BIND8 are now technically obsolete and not considered in this article. Historically, BIND underwent three major revisions, each with significantly different architectures: BIND4, BIND8, and BIND9. It is the most widely deployed DNS server. It is a free software product and is distributed with most Unix and Linux platforms, where it is most often also referred to as named (name daemon). BINDД«IND is the de facto standard DNS server. The software is built to process millions of transactions per second on standard hardware. AnswerX is sold as software working on common servers (no specialized hardware). It can be used for DNS firewall functionality, extensive logging, and a platform for service creation.

AnswerX is a modern resolver, supporting DNSSEC, IPv6, and full subscriber aware policy controls. It has evolved from the Xerocole acquisition. Most Internet users access a recursive server provided by their internet service provider to locate internet hosts such as AnswerXДЄnswerX is Akamai's recursive DNS resolver (rDNS). They also (typically) cache the result to answer potential future queries within a certain expiration (time-to-live) period.

Recursive Servers: recursive servers (sometimes called 'DNS caches', 'caching-only name servers') provide DNS name resolution for applications, by relaying the requests of the client application to the chain of authoritative name servers to fully resolve a network name.

they contain the original set of data, or they can be secondary or slave name servers, containing data copies usually obtained from synchronization directly with the master server, either via a DNS mechanism, or by other data store synchronization mechanisms. Authoritative name servers can be primary name servers, also known as master servers, i.e. 'Acme Example Widgets') would provide its own authority services to respond to address queries, or for other DNS information, for These servers are listed as being at the top of the authority chain for their respective domains, and are capable of providing a definitive answer.

Authoritative server: authoritative name servers publish DNS mappings for domains under their authoritative control.

The two principal roles, which may be implemented either uniquely or combined in a given product are: Excluded from consideration are single-feature DNS tools (such as proxies, filters, and firewalls) and redistributions of servers listed here (many products repackage BIND, for instance, with proprietary user interfaces).ДNS servers are grouped into several categories of specialization of servicing domain name system queries. Each of these DNS servers is an independent implementation of the DNS protocols, capable of resolving DNS names for other computers, publishing the DNS names of computers, or both.
