I love the phone book anaology for DNS. Well done. Thanks :) Week #8 QUIZ 1. Define Domain Name System. The DNS is the phone book of the internet. This is how the machine locates the address when someone tells you to go to spot.org. The Domain Name System translate hostnames to IP addresses and makes it possible to assign Internet names to organizations. The Domain Name System consists of a layered set of DNS servers. The domain name space consists of a tree of domain names. Each node in the tree has resource records. These hold information associated with the domain name. The tree sub-divides into zones. And each consists of connected nodes authoritatively served by an authoritative DNS nameserver. 2. Define a domain. A domain is a subtree of the domain name space and takes the domain name of its top node. Each domain may have its own subtrees, called subdomains. A top-level domain is a child of the root; a second-level domain is a child of a first-level domain….and so on. A domain is a subdomain of another if it is enclosed within that

It consists of a tree of domain names. The Root is located at the top and is represented by a . dot . Each node in the tree has resource records. These hold information associated with the domain name. The Top Level Domains are closest to the Root and are the least specific. The tree sub-divides into zones. And each consists of connected nodes authoritatively served by an authoritative DNS nameserver. One nameserver can host several zones. A Sub-Domain is where a domain's name ends in another domain's name and is therefore part of that larger domain. A resolver looks up the information associated with nodes and repeats through several name servers to find the needed information. Or you could form it as a flat namespace with no structure and only one directory, which is the root directory....
