后缀技术详情的来源与口径
- 来源全部是一手公开数据:IANA 根区数据库(类型、赞助机构 / ccTLD 管理机构、注册局网站、WHOIS、IANA 登记日期)、ICANN gTLD 列表(注册局运营方、委派日期、是否新 gTLD、是否品牌专属后缀、协议是否终止)、根区文件(名称服务器、胶水地址、DS 记录)、IANA RDAP 引导文件(RDAP 服务器)。不使用任何第三方汇总站的数据。
- 频率:根区文件与 ICANN 列表每周核对一次;IANA 单页每天轮换核对一部分,约 4 周覆盖全部后缀。每组数据旁边显示各自的核对日期。
- 根区文件只在完整性校验通过时采用:与官方发布的 MD5 一致、区内 NSEC 记录首尾相连覆盖全部后缀、ZONEMD 与 SOA 序列号一致。任一来源某次下载或校验失败,保留上一次成功的数据和它的核对日期。
- "根区 DS 记录"只说明根区是否为该后缀登记了 DNSSEC 信任锚,不代表验证链此刻一定健康,也不代表每家注册商都支持为你的域名开启 DNSSEC。
- "新通用顶级域名"指 ICANN 2012 年新 gTLD 计划的后缀(ICANN 列表里带申请编号的条目);列表里没有申请编号的条目不作判定。委派到根区的日期不等于开放公开注册的日期。
- 名称服务器的 IP 地址是根区文件里的胶水记录;没有列出的,表示根区没有给出,不代表该服务器没有这类地址。
- 来源里没有的字段不显示,也不写"未知"。
后缀介绍的编写与审核
- 后缀页的"关于"一节是人工编写的。介绍里的每一句都对应一条来源原文摘录,并写明是谁的说法("据注册局介绍""IANA 记录的……")。来源以注册局网站、IANA、ICANN 等一手资料为主。
- 没有出处的内容不写:不写"最受欢迎""最适合"之类的评价,也不替注册局概括它没说过的话。查不到资格说明的后缀,不显示"注册资格"一行 —— 不显示不代表没有限制。
- 维基百科等非一手资料只作补充参考,用于介绍里的背景句(例如国家和地区后缀对应的地区),句中写明"据维基百科",并在来源里单独标出;注册资格、本地存在要求、开放日期等事实只采用一手来源。
- 每条内容在发布前由站长逐条核对来源,页面上写明审核日期;来源页面会变化,我们会按来源重新核对并更新。
已收录事件的收录口径
- 后缀页与注册商页的"本站收录的事件"只记录有出处的事实:价格与协议条款的变化、运营方或所有权变更、停止服务、主权与管辖安排、安全事件与合规处理。后缀回溯 10 年,显示在后缀页;注册商回溯 5 年,显示在注册商页。联盟(带推广链接)与非联盟注册商用同一套标准。
- 每条事件至少有一个一手来源(当事方公告、注册局 / ICANN / 政府或监管机构的文件);媒体报道只作补充;第三方统计报告只在写明统计时期与样本局限时引用,不把样本表现说成整个后缀的结论。
- 每一句都写明是谁的说法("ICANN 称""英国政府的说明称"),只陈述来源说了什么;调查、仲裁或诉讼写明程序状态,不替任何一方下结论。本站不给后缀或注册商打分、排名,也不评价"安全与否"。
- 每条事件发布前由站长逐条核对来源,并设定复审日期,到期未复审的事件不能发布;更正会记在该条事件下。未收录不代表没有发生过其他事件。
