The Domain Name System (DNS) is a hierarchical naming system for computers, services, or any resource connected to the Internet The Internet is a global system of interconnected computer networks that use the standard Internet Protocol Suite to serve billions of users worldwide. It is a network of networks that consists of millions of private and public, academic, business, and government networks of local to global scope that are linked by a broad array of electronic and or a private network In Internet Protocol terminology, a private network is typically a network that uses private IP address space, following the standards set by RFC 1918 and RFC 4193. These addresses are common in home and office local area networks , as globally routable addresses are scarce, expensive to obtain, or their use is not necessary. Private IP address. It associates various information with domain names A domain name is an identification label that defines a realm of administrative autonomy, authority, or control in the Internet, based on the Domain Name System assigned to each of the participants. Most importantly, it translates domain names meaningful to humans into the numerical (binary) identifiers associated with networking equipment for the purpose of locating and addressing these devices worldwide. An often used analogy to explain the Domain Name System is that it serves as the "phone book A telephone directory is a listing of telephone subscribers in a geographical area or subscribers to services provided by the organization that publishes the directory" for the Internet by translating human-friendly computer hostnames A hostname is a label that is assigned to a device connected to a computer network and that is used to identify the device in various forms of electronic communication such as the World Wide Web, e-mail or Usenet. Hostnames may be simple names consisting of a single word of phrase, or they may include the name of a Domain Name System domain at the into IP addresses An Internet Protocol address is a numerical label that is assigned to devices participating in a computer network utilizing the Internet Protocol for communication between its nodes. An IP address serves two principal functions in networking: host or network interface identification and location addressing. The role of the IP address has also been. For example, www.example.com example.com, example.net, and example.org are second-level domain names reserved by the Internet Engineering Task Force through RFC 2606, Section 3, for use in documentation and examples. They are not available for registration translates to 208.77.188.166.

The Domain Name System makes it possible to assign domain names A domain name is an identification label that defines a realm of administrative autonomy, authority, or control in the Internet, based on the Domain Name System to groups of Internet users in a meaningful way, independent of each user's physical location. Because of this, World-Wide Web The World Wide Web, abbreviated as WWW and W3 and commonly known as The Web, is a system of interlinked hypertext documents contained on the Internet. With a web browser, one can view web pages that may contain text, images, videos, and other multimedia and navigate between them using hyperlinks. Using concepts from earlier hypertext systems, (WWW) hyperlinks In computing, a hyperlink is a reference to a document that the reader can directly follow, or that is followed automatically. The reference points to a whole document or to a specific element within a document. Hypertext is text with hyperlinks. Such text is usually viewed with a computer. A software system for viewing and creating hypertext is a and Internet contact information can remain consistent and constant even if the current Internet routing arrangements change or the participant uses a mobile device. Internet domain names are easier to remember than IP addresses such as 208.77.188.166 (IPv4 Internet Protocol version 4 is the fourth revision in the development of the Internet Protocol (IP) and it is the first version of the protocol to be widely deployed. Together with IPv6, it is at the core of standards-based internetworking methods of the Internet. IPv4 is still by far the most widely deployed Internet Layer protocol, as IPv6 is) or 2001:db8:1f70::999:de8:7648:6e8 (IPv6 Internet Protocol version 6 is the next-generation Internet Protocol version designated as the successor to IPv4, the first implementation used in the Internet and still in dominant use currently[update]. It is an Internet Layer protocol for packet-switched internetworks. The main driving force for the redesign of Internet Protocol was the). People take advantage of this when they recite meaningful URLs In computing, a Uniform Resource Locator is a subset of the Uniform Resource Identifier (URI) that specifies where an identified resource is available and the mechanism for retrieving it. In popular usage and in many technical documents and verbal discussions it is often incorrectly used as a synonym for URI, the best-known example of which is the and e-mail addresses An e-mail address identifies a location to which e-mail messages can be delivered. An e-mail address on the modern Internet looks like, for example, jsmith@example.com and is usually read as "jsmith at example dot com". Many earlier e-mail systems had different formats for e-mail addresses, and because modern e-mail systems are partially without having to know how the machine will actually locate them.

The Domain Name System distributes the responsibility of assigning domain names and mapping those names to IP addresses by designating authoritative name servers In computing, a name server consists of a program or computer server that implements a name-service protocol. It maps a human-recognizable identifier to a system-internal, often numeric, identification or addressing component for each domain. Authoritative name servers are assigned to be responsible for their particular domains, and in turn can assign other authoritative name servers for their sub-domains. This mechanism has made the DNS distributed, fault tolerant, and helped avoid the need for a single central register to be continually consulted and updated.

In general, the Domain Name System also stores other types of information, such as the list of mail servers Within Internet message handling services , a message transfer agent or mail transfer agent (MTA) or mail relay is a computer process or software agent that transfers electronic mail messages from one computer to another, in single hop application-level transactions. An MTA implements both the client (sending) and server (receiving) portions of that accept email Electronic mail, often abbreviated as email, e.mail or e-mail, is a method of exchanging digital messages. E-mail systems are based on a store-and-forward model in which e-mail computer server systems accept, forward, deliver and store messages on behalf of users, who only need to connect to the e-mail infrastructure, typically an e-mail server, for a given Internet domain. By providing a worldwide, distributed keyword-based redirection service, the Domain Name System is an essential component of the functionality of the Internet The Internet is a global system of interconnected computer networks that use the standard Internet Protocol Suite to serve billions of users worldwide. It is a network of networks that consists of millions of private and public, academic, business, and government networks of local to global scope that are linked by a broad array of electronic and.

Other identifiers such as RFID tags Radio-frequency identification is the use of an object (typically referred to as an RFID tag) applied to or incorporated into a product, animal, or person for the purpose of identification and tracking using radio waves. Some tags can be read from several meters away and beyond the line of sight of the reader, UPC codes The Universal Product Code is a barcode symbology (i.e., a specific type of barcode), that is widely used in the United States and Canada for tracking trade items in stores, International characters in email addresses and host names, and a variety of other identifiers could all potentially utilize DNS.[1]

The Domain Name System also defines the technical underpinnings of the functionality of this database service. For this purpose it defines the DNS protocol In computing, a protocol is a set of rules which is used by computers to communicate with each other across a network. A protocol is a convention or standard that controls or enables the connection, communication, and data transfer between computing endpoints. In its simplest form, a protocol can be defined as the rules governing the syntax,, a detailed specification of the data structures and communication exchanges used in DNS, as part of the Internet Protocol Suite The Internet Protocol Suite is the set of communications protocols used for the Internet and other similar networks. It is named from two of the most important protocols in it: the Transmission Control Protocol (TCP) and the Internet Protocol (IP), which were the first two networking protocols defined in this standard. Today's IP networking (TCP/IP). The DNS protocol was developed and defined in the early 1980s and published by the Internet Engineering Task Force The Internet Engineering Task Force develops and promotes Internet standards, cooperating closely with the W3C and ISO/IEC standard bodies and dealing in particular with standards of the TCP/IP and Internet protocol suite. It is an open standards organization, with no formal membership or membership requirements. All participants and managers are (cf. History).

In windows AD domain, is there any tools that allows me browse the domain computer system info?
Q. I guess I am trying to find a AD domain system info browser or remote domain client browser. I know I can connect to clients in computer management console but I can only do that one at a time and I have to know the computer name first. Here I am wondering if there is any tool that will just go fetch all the domain computer's system info such as windows version, hard ware summary(ex. hard drive usage), etc.
