Reverse-Dns
反向 dns 未傳播
我在名稱伺服器中為伺服器定義了反向 dns 區域,
muq.ac.ir
它響應域muq.ac.ir
伺服器的名稱解析。80.191.92.199
然後我為帶有 value的 ip 地址添加 ptr 記錄muq.ac.ir
。但是大約 12 小時後,我仍然無法反向查找我的域。我是否錯過了有關 dns 伺服器的資訊,或者我的伺服器不負責反向查找?
或者仍然沒有傳播dns伺服器?
您的 DNS 伺服器不對這個區域負責。您可以使用 dig 請求檢查它:

公共地址由 RIPE 提供,它們將地址委託給其他公司。如果您不是此 IP 地址塊的所有者,則應要求創建 PTR 公司,該公司為您提供此公共 IP。一般來說,它是網際網路服務或託管服務提供商。
