'''Root Zone''' refers to the highest level of the 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]], 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 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>
