'''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>

According to the 2009 report of the Root Scaling Study Team, the  DNS root zone is  small which 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>
