關於 Zayo 的 IP 網段資料

  • ASN 與持有機構

    Zayo 使用 AS6461 宣告前綴。註冊資料中的持有機構：AS6461 (ZAYO-6461 - Zayo Bandwidth)。

  • 清單包含什麼

    清單是這些 ASN 在公開 BGP 路由表裡宣告的前綴（經 RIPEstat 取得），相鄰的區塊不合併。它不是位址歸屬紀錄：可能包含客戶自帶的前綴與轉租的位址段，也可能漏掉只有很少節點看得到的路由。快照日期 2026-11-02。

  • 常見用途

    在防火牆、WAF 或 nginx 中放行 / 攔截來自 Zayo 的流量、替日誌裡的來源 IP 分類，或用 CIDR 比對判斷某個 IP 是否屬於 Zayo。請注意雲端業者與電信業者的位址裡也運行著客戶的業務，整段封鎖可能誤傷無關的服務。

如何使用 Zayo 的 IP 網段清單

  1. 先看上面的表格：IPv4 與 IPv6 各一張，每列有 CIDR、起始 IP – 結束 IP 與位址數。
  2. 按「下載 TXT」或「下載 CSV」取得完整清單，檔案包含全部 262 筆，不只是頁面上顯示的前幾列。
  3. 把 TXT 當成一個位址集合匯入防火牆、路由器或 ipset，或把 CIDR 貼進雲端安全群組的規則裡。
  4. 用於正式環境前先確認快照日期（2026-11-02）；雲端業者的位址段變動頻繁，請再對照業者自己發布的官方範圍檔案。

Zayo IP 網段常見問題

Zayo 有多少個 IP 網段？

截至 2026-11-02，Zayo 透過 AS6461 在公網 BGP 路由表裡宣告了 249 個 IPv4 前綴（共涵蓋 1,761,536 個位址）與 13 個 IPv6 前綴。

Zayo 的 ASN 是多少？

Zayo 使用 AS6461。註冊資料中的持有機構：AS6461 (ZAYO-6461 - Zayo Bandwidth)。大型機構常有多個 ASN，本頁把核對過的都合併在一起。

怎麼用 Zayo 的 IP 網段做防火牆白名單或黑名單？

下載 TXT 檔案（一行一個 CIDR），匯入 ipset、nftables、nginx 的 allow / deny 設定、路由器位址清單或雲端安全群組。262 筆建議整體當成一個位址集合匯入，不要逐條建立規則。請注意 Zayo 的位址裡也運行著客戶的服務，整段封鎖會連帶封掉無關的網站。

Zayo 的 IP 網段清單多久更新一次？

這份清單是 2026-11-02 的快照，大約每週從公開 BGP 資料（RIPEstat）重新產生一次。路由公告每天都在變動，用於正式環境前請重新下載，雲端業者還應對照其官方發布的範圍檔案。
