The domain names and the domain numbers in the internet (national and international)

Domain names are used to identify one or more IP addresses or website. Without domain name user can access to the website with IP (internet protocol). The domain name is just a simple (word format) representation of IP address.

                The domain number in the internet is the IP (internet protocol), which computers use it to communicate among themselves in internet environment. These numbers are exclusive to every PC in internet. As example, when you write ninova.com to the address bar, web browser first converts it into IP address then it guides the user to the computer that possess that PI address. Therefor it is not needed to know IP address of a site to visit it, to make easy access and remember for every site a domain name must be taken. Domain name can be taken from internet service servers or web hosting firms.

                The domain names possess to a hierarchical structure. They are separated with the points from left to right in increasing order. From www.mfa.com.tr the right most part (gon.tr) is TLD (top/first level domain), the middle one (mfa) is SLD (second level domain) and the first level domain names are separated inside it into two parts:

• ·         Generic Top level Domain (gTLD)

gTLD – Generic Top-Level Domains are the most common and the most sought after names. These include .com, .net, .org, .biz, .info, and several others. This names are added in 1984 to the domain name systems and since that time it is being used.

• ·         Country Code Top level Domain (ccTLD)

ccTLD – Country Code Top-Level Domains that were created specifically for a single country’s use. That country can put any sort of restrictions on it that they choose. Some countries only allow citizens to register domains under their ccTLD. Other countries ‘rent’ their TLD out for use by the global public, as in the case with .cc, the official ccTLD for the Cocos Islands, .ws, the official ccTLD for Western Samoa, and .tv, the official ccTLD for Tuvalu. This is a two character suffix which is identified in ISO (international Organizations for Standardization) 3166 standard. In every country they assign these standard with a special institution and in international area it is IANA (internet Assigned Numbers Authority).

Best of lucks :)
