PTI(Public Technical Identifiers)是 [[icann|ICANN]] 的附属机构,根据 2016 年到期的与美国商务部签订的合同履行 [[iana|IANA]] 职能。PTI 于 2016 年作为 IANA 管理权移交的一部分而成立,旨在将 IANA 职能的监督权从美国政府移交给全球多利益相关方社区。PTI 负责运营 [[root-zone|DNS 根区]]、维护协议参数注册表(如端口号、媒体类型),并协调向各区域互联网注册机构分配 IP 地址。PTI 向 ICANN 及更广泛的互联网社区负责,而非向任何单一政府负责。
示例
When a new ccTLD like .ss (South Sudan) needs to be delegated, PTI/IANA processes the request, validates technical criteria, and updates the DNS root zone accordingly.
