使用 API 管理 IP 位址範圍

您可以使用資料擴充 API 來管理 IP 位址範圍。

使用管理IP位址範圍腳本

  1. 使用下列預期的欄位建立 CSV 檔案:Name、IP_Address_Ranges、Category、Tag(id)和Override_ISP_Name。
    以下是 CSV 檔案內容的範例:

    name, ip_address_ranges, category, tag(id), isp_name
    Test 1,200.200.200.200/24 201.201.201.201/24,1, ,
    Test 2,1.1.1.5/32 31.31.31.4/24,1,000000290000000000000000 0000002d0000000000000000  ,
    Test 3,2.2.2.2/32,1,0000002d0000000000000000,
    Test 4,5.6.5.4/32,2,,test
    
  2. 更新下列腳本變數的值:OPTION_DELETE_ENABLEDIP_RANGES_BASE_URL、CSV_ABSOLUTE_PATHYOUR_TOKEN

    重要

    如果您將OPTION_DELETE_ENABLED設為 True,則腳本會從租用戶中刪除任何 IP 位址範圍,但不存在於 CSV 檔案中。 如果您使用此選項,請確定 CSV 檔案會定義租使用者中您想要的所有 IP 位址範圍。

  3. 執行文本以建立新的記錄,並使用相符的名稱更新現有的規則。

要求本文參數

  • “filters”:篩選具有要求所有搜尋篩選的物件,請參閱 數據擴充篩選 以取得詳細資訊。 若要避免您的要求受到節流,請務必包含查詢的限制。
  • “limit”: Integer。 在掃描模式中,介於500到5000之間(預設值為500)。 控制掃描所有資料的反覆項目數目。

回應參數

  • “data”:傳回的數據。 每個反覆項目的記錄數目最多會包含「限制」數目。 如果有更多記錄要提取(hasNext=true),最後幾筆記錄將會卸除,以確保所有數據只會列出一次。
  • “hasNext”: Boolean。 表示是否需要數據上的另一個反覆專案。
  • “nextQueryFilters”:如果需要另一個反復專案,它會包含要執行的連續 JSON 查詢。 在下一個要求中,請使用此參數作為「篩選」參數。

下列 Python 範例會使用 CSV 檔案的內容來管理 適用於雲端的 Defender Apps 環境中的 IP 位址範圍(建立、更新或刪除)。
