An organization obtains authority for parts of the name space and can add additional layers of the hierarchy In practice allocation of the domain names generally follows the allocation of IP address eg All hosts with network prefix 12814316 have domain name suffix virginiaedu All hosts on network 12814313624 are in the Computer Science. It contacts authoritative name server. A domain is a subtree of the DNS name space.
A phylogenetic tree based on rRNA data showing the separation of bacteria archaea and eukaryota domains. Hierarchy of Name Servers Root name servers It is contacted by name servers that can not resolve the name. And the name server returns the IP address corresponding to that domain name to the host so that the host can future connect to that IP address.
Namespace of web is organized into hierarchical layout of subdomains below DNS root domain. DNS Domain Name System Name service in Internet Zone is an administrative unit domain is a subtree. Fully Qualified Domain Name FQDN It is essential to know about Fully Qualified Domain Name FQDN to understand the DNS hierarchy.
The three domains are the Archaea the Bacteria and the Eukarya. DNS is required for the functioning of the internet. In the file system naming is done from the root down but in the domain name system it is done from the bottom to the root.

The Domain Name System. Therefore namespace is subdivided into areas zones for this purpose. Let us see a list of important Domain name system solved MCQs Quesitons Answers.
This hierarchy has multiple levels from 0 to 127 with a root at the top. A Domain can further divided in to sub-domains. The following diagram shows the domain name space hierarchy.
DNS is a service that translates the domain name into IP addresses.
