IANA ASN 分配表IANA ASN allocation table

16 位 / 32 位扩展区间、精确区间数量和数字归属查询；IANA 分配区间不等于具体 ASN 运营商数据库。16-bit / extended 32-bit ranges, exact range counts and numeric membership lookup. An IANA range is not an individual ASN operator database.

如何理解结果Understand the result

有来源的 IANA 快照，不是实时路由或所有权检测。搜索与导出在本地完成。An attributed IANA snapshot, not a live routing or ownership check. Search and export stay local.

原理、限制与隐私说明How it works, limitations & privacy

  • 数据来自本站的同源静态快照；搜索、筛选、排序、分页和导出都在本地进行。仅点击来源链接时才打开权威外部网站。快照抓取时间不等于注册表更新时间。Data loads from this site’s same-origin static snapshot; search, filters, sorting, pagination and exports are local. Source links open authoritative external websites only when clicked. A snapshot retrieval time is not a registry update time.

  • 点击列标题排序。CSV / JSON 导出包含全部筛选结果，不仅当前页。行详情保留来源备注与参考。分配状态不证明当前 BGP 路由、可达性或具体终端用户归属。Click a column heading to sort. CSV/JSON exports include all filtered rows, not only the current page. Source notes and references remain available in row details. Allocation status does not prove current BGP routing, reachability or individual end-user ownership.
