Creating a Domain Model - Essay Example

Creating domain model Insert The Domain system; a hierarchical naming system designed for computers, in any source allied to some private network or internet. The system associates diverse data and facts with domain names allotted to every participant. Significantly, the system converses the domain names which persons can understand, interpreting them into binary or numerical identifiers which are linked with the networking equipment with the reason of addressing and locating these devices globally.

An equivalence which is used often to elucidate the Domain Name System resembles a phone book designed for the Internet. This analogy decodes the computer hostnames as understood through human language; converting them into IP addresses. For example, with the case of the URL, www.suchas.com, it may be converted into 192.0.32.18. The Domain name system is also understood to be a distributed database which maps the IP addresses to the Host names. Utilizing the DNS it is probable to allot domain names to groups of Internet users in a significant way, independent of the actual physical location of each user.

Since this is attainable, the hyperlinks of the World Wide Web (WWW) and the contact information provided by the internet will remain unbroken and dependable even though the prevailing Internet routing measures are changed or altered or a mobile device is used by the participant. It is easier to remember the Internet domain names as opposed to IP addresses; for example, in the case of IPv6, 2001:db8::1f70:6e8 or IPv4, 209.75.188.166. People capitalize on this advantage whenever they talk about expressive e-mail addresses and URLs without requiring to comprehend how the computer will essentially locate them.

The Domain Name System allots the responsibility of allocating domain names and mapping the domain names to IP addresses through the designation of authoritative name servers for every domain. These authoritative name servers are supposed to be in control of their specific domains, acting in turn to allot other authoritative name servers to their sub-domains. This approach has made the domain name system fault tolerant and distributed and has aided in avoiding the demand for one central register to be continually used.

With the presented case, Company Alpha has a prevailing DNS namespace. Diverse locations or establishments may be named with distinct subdomains such as firstname.corp. institu.com or secondname.corp.institu.com to simplify administration. I would consider an immediate action of making the Active directory child domain subordinate to the parent domain in the domain name system namespace (Microsoft.com., 2010). One may opt to create subdomains for institutions within the corporation or the same location.

For instance, secondlevel.firstlevel.corp.institu.com. These are among the few things which the company requires. Similar to all companies, Company Alpha should make use of a redundant domain name system infrastructure. This will aid with backing up the data in the system. With the current information age the power to protect and avail information is essential. ReferencesMicrosoft.com. (2010). Domain Controller Roles.
