DNS DNS, the domain name system, is a distributed database system designed to provide a name to address lookup to computers requesting information over the internet. It is comprised of two main components, A hierarchy and name service. Hierarchy • responsible for the structure, naming conventions, and delegation of authority • Provides a means of managing the distribution database system. DNS name service • Provides the actual name to address mapping mechanism. Figure 1 Domain Naming Scheme • Follows the structure of the DNS hierarchy. • Can be defined as a list of all domains in the path from the local domain to the root. • Each level of the domain name is followed by a period, or dot. o i.e. technet.microsoft.com. Is the domain name for the TechNet domain (see Figure 1). • Domain name is followed by a period. o This represents the root domain. o Known as a Fully Qualified Domain Name (FQDN). The DNS domain • Provides the label of the DNS tree. • Each node represents a domain. • Domains under top level domains are known as individual entities. • Top level domains can be further divided into subdomains. • Manages the information of an entity’s host computers. • Domains at the leaves of the tree typically represent individual hosts. DNS hostname • Any computer that uses DNS • reflects the computer’s position in the DNS hierarchy o i.e. The DNS hostname for host 2 (see Figure 1) would be host2.technet.microsoft.com. Any domain in a subtree is considered part of all the domains above it, so the technet.microsoft.com. domain is part of the microsoft.com domain., which is a part of the com. domain. • A full domain name can consist of up to 255 characters, however some systems may have a smaller number as... ... middle of paper ... ...org/topics/internet/48405289.jpg http://technet.microsoft.com/en-us/library/cc723704.aspx http://technet.microsoft.com/en-us/library/cc731204(v=ws.10).aspx http://support.microsoft.com/kb/232025/EN-US http://compnetworking.about.com/od/dns_domainnamesystem/f/what-is-a-dns-cache.htm http://technet.microsoft.com/en-us/library/Bb962069.tcpipm03_big(l=en-us).gif http://kb.iu.edu/data/aiuv.html http://www.techrepublic.com/article/know-how-to-distinguish-dns-query-types/#. http://www.tech-forums.net/forums/f9/where-dns-cache-stored-64578/ http://www.youtube.com/watch?feature=player_detailpage&v=3EvjwlQ43_4 http://technet.microsoft.com/en-us/library/cc781340(v=ws.10).aspx http://www.zytrax.com/books/dns/ch8/ http://tools.ietf.org/html/rfc3596#section-2.1 http://tools.ietf.org/html/rfc2782 http://support.microsoft.com/kb/232025/EN-US http://it.med.miami.edu/x1111.xml
