DNS 5 REFUSED vs 10 NOTZONE
Both DNS 5 (REFUSED) and 10 (NOTZONE) belong to the DNS Response Codes (RCODEs) category. 5 indicates that query refused. The name server refuses to perform the requested operation for policy reasons. Meanwhile, 10 means that name not contained in zone. A name used in the Prerequisite or Update section is not within the zone denoted by the Zone section.
説明
Query refused. The name server refuses to perform the requested operation for policy reasons.
このコードが表示される場合
The server rejected your query due to access control — for example, a recursive resolver that only serves its own network, or a zone transfer blocked by ACL.
解決方法
Check the server's allow-query, allow-recursion, or allow-transfer ACLs. If you are not authorized to use this resolver, switch to a public DNS service.
説明
Name not contained in zone. A name used in the Prerequisite or Update section is not within the zone denoted by the Zone section.
このコードが表示される場合
Your dynamic update tried to modify a record that falls outside the zone specified in the update message (e.g., updating foo.example.org in the example.com zone).
解決方法
Ensure all names in the update are within the target zone. Check for typos in the zone name or the records being updated.
