关于 AT&T 的 IP 段数据

  • ASN 与持有机构

    AT&T 使用 AS7018 宣告前缀。注册信息里的持有机构：AS7018 (ATT-INTERNET4 - AT&T Enterprises, LLC)。

  • 列表包含什么

    列表是这些 ASN 在公开 BGP 路由表里宣告的前缀（经 RIPEstat 取得），相邻的块不合并。它不是地址归属记录：可能包含客户自带的前缀和转租的地址段，也可能漏掉只有很少节点能看到的路由。快照日期 2026-11-02。

  • 常见用途

    在防火墙、WAF 或 nginx 里放行 / 拦截来自 AT&T 的流量，给日志里的来源 IP 归类，或用 CIDR 匹配判断某个 IP 是否属于 AT&T。注意云厂商和运营商的地址里也运行着客户的业务，整段封禁可能误伤无关的服务。

怎么使用 AT&T 的 IP 段列表

  1. 先看上面的表格：IPv4 和 IPv6 各一张，每行有 CIDR、起始 IP – 结束 IP 和地址数。
  2. 点「下载 TXT」或「下载 CSV」获取完整列表，文件包含全部 638 条，不只是页面上显示的前几行。
  3. 把 TXT 作为一个地址集合导入防火墙、路由器或 ipset，或把 CIDR 粘贴进云安全组的规则里。
  4. 用于生产环境前先看快照日期（2026-11-02）；云厂商的地址段变动频繁，请再对照厂商自己发布的官方范围文件。

AT&T IP 段常见问题

AT&T 有多少个 IP 段？

截至 2026-11-02，AT&T 通过 AS7018 在公网 BGP 路由表里宣告了 624 个 IPv4 前缀（共覆盖 96,428,800 个地址）和 14 个 IPv6 前缀。

AT&T 的 ASN 是多少？

AT&T 使用 AS7018。注册信息里的持有机构：AS7018 (ATT-INTERNET4 - AT&T Enterprises, LLC)。大型机构常有多个 ASN，本页把核对过的都合并在一起。

怎么用 AT&T 的 IP 段做防火墙白名单或黑名单？

下载 TXT 文件（一行一个 CIDR），导入 ipset、nftables、nginx 的 allow / deny 配置、路由器地址列表或云安全组。638 条建议整体作为一个地址集合导入，不要逐条建规则。注意 AT&T 的地址里也运行着客户的服务，整段封禁会连带封掉无关的网站。

AT&T 的 IP 段列表多久更新一次？

这份列表是 2026-11-02 的快照，大约每周从公开 BGP 数据（RIPEstat）重新生成一次。路由公告每天都在变化，用于生产环境前请重新下载，云厂商还应对照其官方发布的范围文件。
