Geodns — a DNS traffic-steering method that selects answers using the apparent geographic location of the requester or its recursive resolver.
A DNS result depends on authoritative data, delegation, resolver state, and network reachability. The same visible symptom can have different causes, so the response code and query path must be examined together.
Geodns — a DNS traffic-steering method that selects answers using the apparent geographic location of the requester or its recursive resolver.
Possible causes include a nonexistent name, authoritative-server failure, access policy, stale cache, incorrect delegation, or a network timeout. The exact meaning depends on the response code and where it was generated.
Test through multiple resolvers and then query the authoritative servers directly. Compare the response code, DNS sections, TTL, DNSSEC validation, and UDP/TCP port 53 reachability.
