The platform that manages the domain, such as Active Directory Domain Services ( AD DS), commonly includes features to help client computers locate the nearest resources and optimize processes such as replicating directory data between distributed servers.Ī common network domain used today is Active Directory designed by Microsoft for Windows domain networks. The domain also enables users on the network to communicate and collaborate.Ī domain can include resources and users on a local area network ( LAN) and wide area network ( WAN). A user logs in to the domain to access the approved resources, regardless of where the resources are located on the network. Administrators can apply policies to network resources at a granular level. Administrators can control which resources a user can access and the user's level of access.Ī network domain makes it possible to organize network resources and users based on the needs of the organization and the types of resources connected to the network. It also provides a mechanism for authorizing and authenticating users for network access. A network domain typically includes servers, desktops, printers and other devices. This type of domain provides a structure for managing network resources and users under a single administrative umbrella. The term domain is also used in other types of networks to describe the logical organization of connected physical network resources and users. Some DNSes already have the required information cached and relay it back to a client so they can get online. Domain name servers (DNSes) communicate to client's query. A second-tier domain can also include subdomains, as in or, which are part of the second level domain. Each second-level domain is associated with a specific TLD, as indicated by the final component of the domain name. Individual domains - such as, or - sit directly beneath the TLDs. gov and several other domains, including country codes. TLDs identify geographic or purpose commonality, such as a nation or commercial enterprise. The root domain contains multiple top-level domains ( TLDs) that sit directly beneath it in the DNS hierarchy. DNS simplifies communications using a hierarchical naming structure.Īt the top of this hierarchy is the Root domain, which serves as the parent node for all internet domains. These addresses make it possible for a device connected to the internet to communicate directly with a specific domain. Internet domains are identified by unique IP addresses. For example, DNS makes it possible for users to type in a browser to connect to the TechTarget website, without knowing the associated IP address. The DNS system allows internet users to access content by remembering a name rather than an IP address. The service acts as a giant directory for resolving domain names to IP addresses and IP addresses to domain names, irrespective of where the domains are located. It is implemented as a decentralized, hierarchical system that's distributed globally across a conglomeration of DNS servers. DNS is an essential component of the internet. Internet domains are set up in accordance with the Domain Name Service ( DNS), an application layer protocol and service used on networks to translate host names to their associated IP addresses. The terms "domain" and "domain name" are often used interchangeably (in context of the internet) because the domain structure is associated with how domains are named. What is an internet domain?Īn internet domain is an administrative structure for organizing, delivering and accessing services on the internet. In general, a domain is an area of control or a sphere of knowledge. Specific to the internet, the term domain can refer to how the internet is structured, and domain also refers to how an organization's network resources are organized.
