The Domain Name System
A name that identifies one or more IP addresses. For example, the domain name microsoft.com represents about a dozen IP addresses. Domain names are used inURL's to identify particular Web pages. For example, in the URL http://www.hotmail.com/ the domain name is hotmail.com.
Every domain name has a suffix that indicates which top level domain (TLD) it belongs
to. There are only a limited number of such domains. For example:
· gov - Government agencies
· edu - Educational institutions
· org - Organizations (nonprofit)
· mil - Military
· com - commercial business
· net - Network organizations
· ca - Canada
· th - Thailand
Because the Internet is based on IP addresses, not domain names, every Web Server
requires a Domain Name System server to translate domain names into IP addresses.
The Internet Protocol addresss is a 32- bit integer. If somebody wants to send a
message it is necessary to include the destination address, but people prefer to assign
machines pronounceable, easily remembered names (host names). For this reason the
Domain Name System is used. These logical names also allow independence from
knowing the physical location of a host. A host may be moved to a different network,
while the users continue to use the same logical name. The Domain Name System (DNS)
is a distributed database used by TCP/IP applications to map between hostnames and IP
addresses, and to provide electronic mail routing information. Each site (university
department, campus,company, or department within a company, for example) maintains
its own database of information and runs a server program that other systems across the
Internet can query. T...

DNS Formatting:
When the user wants to send a message, it invokes an application program and
supplies the name of a machine with which the application must communicate. The
application program must find the machine's IP address. It passes the domain name to a
local resolver (L.R.) and requests an IP address. The local resolver checks its cache and:
If the L.R. has an answer, it returns the answer.
If the L.R. hasn't one, it sends the message to the server. The server then returns a similar
message that contains the answer to the questions for which the server has bindings. If the
server can't answer, it sends responsive information about other servers that the client can
contact.

Binding: In order to run the function the RPC must know what server to contact and where. If this changes for any reason, or there are multiple servers that could run the function it needs to know which one to use (Wills, 1998).
IPv4 is the original internet addressing system. It is a protocol which was used on packet-switched networks. Delivery model is how it operates at its best without a guaranteed avoidance of duplicate in delivery or assurance of proper sequencing. Some aspects include data integrity which is mostly addressed by TCP. IPV4 uses binary notation to sort at time IP address that consist of 32 bits. It is a practice to convert the 32 bits of an IPv4 address into four 8 bit known as octets. With each octet converted to a decimal number (base 10) from (0–255) and parted by a period developed a format called dotted decimal notation. IPv4 has a category of address class types: Class A, B, C, D and E. The class A addresses are used for big networks and always start with zero bits. Each Class A address network can hold up as many as 16,777,216 hosts.
Network Address Translation (NAT) is a standard used to allow multiple PCs on a private network to share a single, globally routable IPv4 address. NAT enables a user to have a large set of addresses internally and usually one address externally. The main reason NAT is often deployed is because IPv4 addresses are getting scarce. NAT is an immediate, but temporary, solution to the IPv4 address exhaustion problem that will eventually be rendered unnecessary with the deployment of the IPv6. The Internet Engineering Task Force has been aware of the impending depletion of the current address space for almost a decade.
Ten years ago, the Internet as we know it hit screens. It was 1995 when Explorer and Netscape emerged as the leading browsers for Internet users. Of course, a lot has changed since the days when it took several minutes to load one Web page. Today, URLs are as common as phone numbers for most businesses.
Intellectual property resembles brick-and-mortar businesses and in the world of e-business, laws and principles govern IP just as in traditional business. Among all intellectual property, domain names are unique to doing e-business and are functionally different from trademarks (Simensky, Bryer & Wilkof, 1999). Although intellectual property may be globally used in e-business, they are subject to laws the country in which the e-business operates. There are however, some basic global trademark law principles and use of domain names as required by the Internet Corporation for Assig...
Other forms of Internet regulation is domain registration, IP address control, etc. In domain registration, once a domain is purchased the Webmaster’s address has to be registered at the time of purchase.

When you log onto the Internet using Netscape or Microsoft's Internet Explorer or some other browser, you are viewing documents on the World Wide Web. The current foundation on which the WWW functions is the programming language called HTML. It is HTML and other programming imbedded within HTML that make possible Hypertext.
“Cybersquatting is the practice of registering a domain name that is the trademark of another person or company in the hopes that the owner will pay huge amounts of money to acquire the URL,” (Schneider, Gary P, p. 333, 2015). In addition, under common law, Nissan Motor Company had trade name rights. Since Nissan was established before Uzi Nissan’s company, the name “Nissan” identified Nissan Motor Co.
