DNS

7 YXRRSET

RR Set Exists when it should not. A resource record set exists that the update prerequisite says should not.

このコードが表示された場合

A DNS UPDATE failed because a specific RRset (e.g., an A record) already exists when the prerequisite required it to be absent.

修正方法

Delete the conflicting RRset before retrying the update, or adjust your prerequisite conditions to match the actual zone state.
