By at the moment. To add to the list of home computers satae into the ARPA NET network needs to send the data.By FTP into the Host Table updates that an administrator who is the SRI will be updated.The data just twice a week only. Make data management is flexible and is not delayed. In additionNetworks that connect it to the freedom to manage their own systems management, so there.The idea of distributing responsibilities in this system. With this virtual world space throughout By providing a homestay satae under the scope of any one area that has been split. By each area.As a past where smaller is not limited to that area, it was referred to a larger area as a hierarchy to be able to specify the position of each host's reference under the scope of each area correctly and quickly. By virtual space for each section is called a "domain" (the Domain), and the reference system referred to as the hierarchy with the name of the individual or the domain "domain name system" (Domain Name System) best of all virtual world space is composed of many smaller areas, this is called "Domain Name Space".What is DNS? Domain Name System (DNS) system this is the system name to the management IP address numbers, with the hierarchical database structure to store information that is called quickly.The main mechanism of the DNS system is n converts IP address name and number information, or do the reverse.
