CNAME 追蹤
CNAME 追逐是指針對初始查詢的 CNAME 記錄答案,後續查詢 DNS 名稱的動作。公用 DNS 解析工具會根據設定,執行後續的 CNAME 答案查詢。一般來說,公開解析器會追蹤任何公開區域中的 CNAME 解答。
當 Trusted Cloud VM 使用中繼資料伺服器 (169.254.169.254
) 做為名稱伺服器,且虛擬私人雲端網路的傳出伺服器政策中未定義替代名稱伺服器時,Cloud DNS 會執行 CNAME 追尋,如下表所述。
CNAME 答案的來源 |
Cloud DNS 解析器行為 |
Cloud DNS 私人區域
含有本機記錄 (非轉送區域)
|
Cloud DNS 系統會在已授權使用虛擬私有雲網路的 Cloud DNS 私人區域中,查詢 CNAME 答案。
Cloud DNS 系統「不會」在任何公開 DNS 區域 (包括 Cloud DNS 公開區域) 中執行 CNAME 答案查詢。
|
Cloud DNS 轉送區域
|
Cloud DNS 系統不會針對從轉送目標名稱伺服器收到的任何 CNAME 答案執行查詢。 |
Cloud DNS 回應政策區域
|
Cloud DNS 系統不會針對從回應政策區域的本機資料規則收到的任何 CNAME 答案執行查詢。 |
