'''根区域'''指的是[[DNS|域名系统]](DNS)结构的最高级别。它包含所有顶级域名，比如[[gTLD|通用顶级域]]（gTLD）([[.com]], [[.net]], [[.org]],[[.jobs]])，以及所有国家代码顶级域（[[ccTLD|ccTLDs]]），比如([[.us]],[[ .uk]] [[.ph]])的名称和数字IP地址，包括所有根服务器的完整列表。<ref>[http://www.isoc.org/briefings/019/ www.isoc.org]</ref>
'''Root Zone''' refers to the highest level of the [[DNS|Domain Name System]] (DNS) structure. It contains the names and the numeric IP addresses for all the top level domain names such as the [[gTLD]]s ([[.com]], [[.net]], [[.org]], [[.jobs]]), and all the country code top level domains ([[ccTLD]]s), for example ([[.us]], [[.uk]] [[.ph]]), including the entire list of all the root servers.<ref>[http://www.isoc.org/briefings/019/ www.isoc.org]</ref>
The DNS root zone contains only 280 delegations of generic, country code and internationalized [[TLD|top level domain names]] (TLD)s and its size is more or less 80,000 bytes. It also changes slowly and absorbs only one minor change per TLD every year.<ref>
