Every computer connected to the internet, commonly called a host has a different identity and unique. Computer identities are numbers and names.
technically, every computer on the network has an identity number called nomot Ip Address (Internet Protocol Address). This ID number can be assumed as a telephone number on a conventional communication network. The array consists of four groups of numbers separated by periods, such as 192.168.0.1 or 202.152.25.155.
In a local computer network, this numbering is usually set by the network administrator of the computer. While every computer connected to the internet get the IP number of internet access service providers.
For each host, or computer on the Internet, it can be remembered more easily then the naming of computer addresses is used. naming this is called the DNS (Domain Name System). The computer name is alphabetical with certain encodings. Each code name is separated by a dot (dot). Examples are smitdev.com, mozilla.org, and so on
For example, consider the following domain name structure.
www.smitdev.com
www: Type of internet network service, that is type of web service
smitdev: domain owner name, or commonly called second level domain, that is SmitDev institution
com: domain suffix, or commonly used top level domain, implements domain type or domain location, that is, domain type of domain.
TLD (Top Level Domain) has some special codes. Some of them can be seen below.
.com: explains the type of commercial domain.
.net: describes the type of internet service domain.
.org: describes the organization's domain type.
.mil: explain the type of military domain
.edu: explain the type of education domain
.gov: explain the type of government domain
.co.id: explains the type of commercial domain originating from Indonesia.
.co.uk: describes the commercial domain type originating from Inggirs (United Kingdom).
If we look, some TLDs use two alphabets as suffixes that indicate the location of the origin of the domain. The domain location code is commonly called ccTLD (Country Codes Top Level Domain). The location code is determined by country code. The ccTLD examples are as follows.
- .id: Indonesia
- .my: Malaysia
- .sg: Singapore
- .jp: Japan
- .kr: South Korea
- .in: India
- .au: Australia
- .it: Italy
- .ca: Canada
- .de: Germany
- .fr: France
- .ru: Russia
- .uk: English
- .us: United States
The full ccTLD code can be found on the original IANA website at http://www.iana.org/cctld/cctld-whois.htm
Domain name creation should we do through the registration process on the Internet. Domain names are managed by an Internet agency called ICANN. The implementation of the resegitration is delegated to the institutions that serve the domain registration. This institution is commonly called a registrar. Examples of these registrars include netsol.com, register.com, and domainsite.com.
