Confirming the Applicant’s control over the requested IP Address by confirming the presence of a Request Token or Random Value contained in the content of a file or webpage in the form of a meta tag under the “/.well-known/pki-validation” directory, or another path registered with IANA for the purpose of validating control of IP Addresses, on the IP Address that is accessible by the CA via HTTP/HTTPS over an Authorized Port. The Request Token or Random Value MUST NOT appear in the request.
確認憑證機構（Certification Authority，CA）可透過 HTTP/HTTPS 在授權連接埠（Authorized Port）存取 IP 位址（IP Address）上的特定檔案或網頁，檢查內容是否存在以 HTML <meta> 標籤包含的請求符記（Request Token）或隨機值（Random Value），以確認申請者（Applicant）對所請求 IP 位址的控管權。該檔案或網頁必須位於「/.well-known/pki-validation」目錄下，或者用以驗證 IP 位址控管權而由 IANA 登記的其他路徑。請求符記或隨機值不得（MUST NOT）出現在請求 IP 的驗證路徑中。
If a Random Value is used, the CA SHALL provide a Random Value unique to the certificate request and SHALL not use the Random Value after the longer of:
若使用隨機值，CA 應（SHALL）提供該憑證申請唯一的隨機值，且在以下最長期限後不得（SHALL NOT）再使用該隨機值：
- 30 days or
- if the Applicant submitted the certificate request, the time frame permitted for reuse of validated information relevant to the certificate (such as in Section 4.2.1 of this document).
- 30 日；或
- 若申請者主動送出憑證申請，則期限為可重複使用與憑證相關之已驗證資料的時間允許範圍（例如本文件第 4.2.1 節所載）。
CAs performing validations using this method MUST implement Multi-Perspective Issuance Corroboration as specified in Section 3.2.2.9. To count as corroborating, a Network Perspective MUST observe the same challenge information (i.e. Random Value or Request Token) as the Primary Network Perspective.
使用此方法進行驗證的 CA 應（MUST）實施第 3.2.2.9 節所規範之多視角簽發佐證（Multi-Perspective Issuance Corroboration）。若要算作有效佐證，其他網路視角（Network Perspective）應（MUST）觀察到與主要網路視角（Primary Network Perspective）相同的挑戰資訊（即隨機值或請求符記）。
