公共遞歸名稱服務(也稱為公共DNS解析)是一種名稱服務器服務,用於替換或補充本地互聯網服務供應商(ISP)的提供的域名系統(DNS)。

使用公共DNS可能包括以下原因:

  • 與使用ISP的DNS服務相比,速度更快[1]
  • 過濾(安全、廣告攔截、成人內容等)[2]
  • 統計[3]
  • 避開審查制度[4]
  • 冗餘 (智能緩存)[5]
  • 訪問官方DNS根中沒有的非官方頂級域名
  • ISP的DNS服務暫時無法使用

個別公共DNS服務運營商將保護隱私作為其服務的一個優勢;有批評者認為,使用這些服務公共DNS潛在大規模數據收集的風險。

公共DNS解析由商業公司運營向公眾免費提供服務,或者由私人愛好者運營用於傳播新技術和支持非營利社區。個別服務商開始提供安全DNS查詢傳輸服務,如DNS over HTTPS(DoH)和DNS over TLS(DoT)。
