BIND, or named, is the most widely used Domain Name System (DNS) software on the Internet.
|
On Unix-like operating systems it is the de facto standard. It performs both of the main DNS server roles – acting as an authoritative name server for one or more specific domains, and acting as a recursive resolver for the DNS system generally.
The djbdns software package is a DNS implementation. It was created by Daniel J. Bernstein in response to his frustrations with repeated security holes in the widely used BIND DNS software. As a challenge, Bernstein offered a $1000 prize for the first person to find a security hole in djbdns, which was awarded in March 2009 to Matthew Dempsky.
A name server is a computer application that implements a network service for providing responses to queries against a directory service. It translates an often humanly meaningful, text-based identifier to a system-internal, often numeric identification or addressing component. This service is performed by the server in response to a service protocol request.
A root name server is a name server for the root zone of the Domain Name System (DNS) of the Internet. It directly answers requests for records in the root zone and answers other requests by returning a list of the authoritative name servers for the appropriate top-level domain (TLD). The root name servers are a critical part of the Internet infrastructure because they are the first step in translating (resolving) human readable host names into IP addresses that are used in communication between Internet hosts.
In Internet computing, NSD is an open-source Domain Name System (DNS) server. It was developed by NLnet Labs of Amsterdam in cooperation with the RIPE NCC, from scratch as an authoritative name server. The intention of this development is to add variance to the "gene pool" of DNS implementations
used by higher level name servers and thus increase the resilience of DNS against software flaws or exploits.
The DNS root zone is the top-level DNS zone in the hierarchical namespace of the Domain Name System (DNS) of the Internet.
DNS zone transfer, also sometimes known by the inducing DNS query type AXFR, is a type of DNS transaction. It is one of the many mechanisms available for administrators to replicate DNS databases across a set of DNS servers.
PowerDNS is a DNS server, written in C++ and licensed under the GPL. It runs on most Unix derivatives. PowerDNS features a large number of different backends ranging from simple BIND style zonefiles to relational databases and load balancing/failover algorithms. A DNS recursor is provided as a separate program.
Microsoft DNS is the name given to the implementation of domain name system services provided in Microsoft Windows operating systems.
A DNS zone is any distinct, contiguous portion of the domain name space in the Domain Name System (DNS) for which administrative responsibility has been delegated to a single manager.
A Domain Name System (DNS) zone file is a text file that describes a DNS zone. A DNS zone is a subset, often a single domain, of the hierarchical domain name structure of the DNS. The zone file contains mappings between domain names and IP addresses and other resources, organized in the form of text representations of resource records (RR). A zone file may be either a DNS master file, authoritatively describing a zone, or it may be used to list the contents of a DNS cache.
pdnsd is a caching DNS proxy server created originally by Thomas Moestl and currently maintained by Paul Rombouts.
This article presents a succinct comparison of the features, platform support, and packaging of many independent implementations of Domain Name System (DNS) name server software.
DNS management software is computer software that controls Domain Name System (DNS) server clusters. DNS data is typically deployed on multiple physical servers. The main purposes of DNS management software are:
mysqlBind/unxsBind is a DNS management software system. It supports Internet Systems Consortium BIND Domain Name System (DNS) and is distributed as open source software under the GNU General Public License.
MaraDNS is an open-source Domain Name System (DNS) implementation, which acts as either a caching, recursive, or authoritative nameserver.
Cisco Prime Network Registrar (CNR) is a Cisco software product that includes components for Domain Name System (DNS) services, Dynamic Host Configuration Protocol services, Trivial File Transfer Protocol (TFTP) services, and Simple Network Management Protocol functions. CNR provides a regional and local management structure and is supported on server hardware and software based on 32-bit and 64-bit architectures. This product is now called Cisco Prime Network Registrar.
Knot DNS is an open-source authoritative-only server for the Domain Name System. It was created from scratch and is actively developed by CZ.NIC, the .CZ domain registry. The purpose of this project is to supply an alternative open-source implementation of an authoritative DNS server suitable for TLD operators to increase overall security, stability and resiliency of the Domain Name System. It is implemented as a multi-threaded daemon, using a number of programming techniques and data structures to make the server very fast, notably Read-copy-update or a special kind of a radix tree.
