What do these issues mean?
- REFUSED — Server is online but refuses queries from outside its network. Likely an ISP resolver that only serves its own subscribers.
- NX_HIJACK — Server works but redirects non-existent domain lookups to its own IP, typically showing ads instead of an error.
- SERVFAIL — Server responds but returns internal errors. May be misconfigured or overloaded.
- NETWORK_ERROR — Connection to the server failed at the network level.
- NO_ANSWER — Server responds to the query but provides no answer data.
- CENSORED — Server returns different results for certain domains compared to neutral resolvers.
