IBM Cloud のIPレンジデータについて

  • ASNと保有組織

    IBM CloudはAS36351からプレフィックスを広報しています。レジストリ上の保有組織：AS36351 (SOFTLAYER - IBM Cloud)。

  • リストに含まれるもの

    これらのASNが公開BGPルーティングテーブルで広報しているプレフィックス（RIPEstat経由で取得）で、隣り合うブロックは統合していません。アドレスの所有記録ではないため、顧客が持ち込んだプレフィックスや貸し出しているアドレスが含まれたり、ごく少数の接続先にしか見えない経路が含まれなかったりすることがあります。取得日：2026-11-02。

  • 主な用途

    ファイアウォール、WAF、nginxでIBM Cloudからの通信を許可・遮断する、ログの送信元IPをネットワーク別に分類する、CIDR照合であるIPがIBM Cloudのものか判定する、といった使い方です。クラウドや通信事業者のアドレスでは顧客のサービスも動いているため、ネットワーク全体を遮断すると無関係なサイトまで巻き込むことがあります。

IBM Cloud のIPレンジリストの使い方

  1. まず上の表を確認します。IPv4とIPv6が別の表になっていて、各行にCIDR、開始IP – 終了IP、アドレス数が載っています。
  2. 「TXTをダウンロード」または「CSVをダウンロード」で全件のリストを取得します。ページに表示した先頭の行だけでなく、全415件が入っています。
  3. TXTを1つのアドレスセットとして、ファイアウォール、ルーター、ipsetに取り込むか、CIDRをクラウドのセキュリティグループのルールに貼り付けます。
  4. 本番で使う前にスナップショット日（2026-11-02）を確認してください。クラウドのレンジは変更が多いので、事業者が公開している公式のレンジファイルとも照らし合わせます。

IBM Cloud のIPレンジに関するよくある質問

IBM CloudのIPレンジはいくつありますか？

2026-11-02時点で、IBM CloudはAS36351から、公開BGPルーティングテーブルに342件のIPv4プレフィックス（合計3,642,880アドレス）と73件のIPv6プレフィックスを広報しています。

IBM CloudのASNは何ですか？

IBM CloudはAS36351を使っています。レジストリ上の保有組織：AS36351 (SOFTLAYER - IBM Cloud)。大きな組織はASNを複数持つことが多く、このページでは確認できたものをまとめています。

IBM CloudのIPレンジをファイアウォールの許可リスト・拒否リストに使うには？

TXTファイル（1行1CIDR）をダウンロードし、ipset、nftables、nginxのallow/denyの設定、ルーターのアドレスリスト、クラウドのセキュリティグループに取り込みます。415件は1件ずつルールにせず、1つのアドレスセットとして取り込むのがおすすめです。IBM Cloudのアドレスでは顧客のサービスも動いているため、全体を遮断すると無関係なサイトにも影響します。

IBM CloudのIPレンジはどのくらいの頻度で更新されますか？

このリストは2026-11-02のスナップショットで、おおよそ週に1回、公開BGP情報（RIPEstat）から作り直します。経路の広報は毎日変わるため、本番で使う前に再ダウンロードしてください。クラウド事業者の場合は、公式に公開されているレンジファイルとも照らし合わせてください。
