List of DNS record typesThis is an overview of resource records (RRs) permissible in zone files of the Domain Name System (DNS). It also contains pseudo-RRs.Resource recordsOther types and pseudo-RRsOther types of records simply provide some types of information (for example, an HINFO record gives a description of the type of computer/OS a host uses), or others return data used in experimental features. The "type" field is also used in the protocol for various operations.
Nslookupnslookup (from name server lookup) is a network administrationcommand-line tool for querying the Domain Name System (DNS) to obtain the mapping between domain name and IP address, or other DNS records. Overviewnslookup is a member of the BIND name server software. Andrew Cherenson created nslookup as a class project at UC Berkeley in 1986 and it first shipped in 4.3-Tahoe BSD.
Domain Name SystemThe Domain Name System (DNS) is a hierarchical and distributed name service that provides a naming system for computers, services, and other resources on the Internet or other Internet Protocol (IP) networks. It associates various information with domain names (identificationstrings) assigned to each of the associated entities.Name serverA 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.
Time to liveTime to live (TTL) or hop limit is a mechanism which limits the lifespan or lifetime of data in a computer or network. TTL may be implemented as a counter or timestamp attached to or embedded in the data. Once the prescribed event count or timespan has elapsed, data is discarded or revalidated. In computer networking, TTL prevents a data packet from circulating indefinitely.
Internationalized domain nameAn internationalized domain name (IDN) is an Internet domain name that contains at least one label displayed in software applications, in whole or in part, in non-Latin script or alphabet or in the Latin alphabet-based characters with diacritics or ligatures. These writing systems are encoded by computers in multibyte Unicode. Internationalized domain names are stored in the Domain Name System (DNS) as ASCII strings using Punycode transcription.DNS root zoneThe DNS root zone is the top-level DNS zone in the hierarchical namespace of the Domain Name System (DNS) of the Internet. Before October 1, 2016, the root zone had been overseen by the Internet Corporation for Assigned Names and Numbers (ICANN) which delegates the management to a subsidiary acting as the Internet Assigned Numbers Authority (IANA). Distribution services are provided by Verisign.Host (Unix)host is a simple utility for performing Domain Name System lookups.Resolv.confresolv.conf is a computer file used in various operating systems to configure the system's Domain Name System (DNS) resolver. The file is a plain-text file usually created by the network administrator or by applications that manage the configuration tasks of the system. The resolvconf program is one such program on FreeBSD or other Unix machines which manages the resolv.conf file.

Network managementNetwork management is the process of administering and managing computer networks. Services provided by this discipline include fault analysis, performance management, provisioning of networks and maintaining quality of service. Network management software is used by network administrators to help perform these functions. TechnologiesA number of applications and protocols exist to support network and network device management.
Console applicationA console application or command-line program is a computer program (applications or utilities) designed to be used via a text-onlyuser interface. A console application can be used with a computer terminal, a system console, or a terminal emulator included with a graphical user interface (GUI) operating system, such as the Windows Console in Microsoft Windows, the Terminal in macOS, and xterm in the X Window System on Unix-like systems.*As an Amazon Associate I earn from qualifying purchases.
