Domain Name System, or DNS, is the most recognized system for assigning addresses to Internet web servers. Somewhat like international phone numbers, the domain name system helps to give every Internet server a memorable and easy-to-spell address. Simultaneously, the domain names keep the really technical IP address invisible for most viewers.There are only a limited number of such domains. For example:
gov – Government agenciesedu – Educational institutionsorg – Organizations (nonprofit)mil – Militarycom – commercial businessnet – Network organizationsca – Canadath – Thailandinfo – Information
