This DNS lookup ran on 2026-10-03 11:00 UTC. The overall DNS response rate was 30%, with only 1 of 307 nodes returning a valid result and a median DNS lookup time of 357 ms. Most nodes did not obtain the valid result defined for this test,
mctarot.cn DNS lookup performance by network
DNS response rate counts probes with a DNS response and measured lookup time. P50 is the time at or below which half of responding lookups completed; a response need not contain an address and does not establish propagation or poisoning.

Key findings
- The overall DNS response rate was 30%: 1 of 307 nodes returned a valid resolved result, while 306 were unanswered lookups.
- Telecom nodes showed an 80% response rate with a 357 ms median DNS lookup time; unicom, mobile, and overseas nodes showed 0% response, so no comparable lookup timing was available for them.
- Only one observed resolved address appeared, so the unique response IP count indicates limited answer diversity and does not establish resolution correctness or a root cause.
- No node errors were recorded; the failures appear as nodes that did not obtain the valid result defined for this test.
Improvement recommendations
- The DNS response rate is 0%, below the 99% review threshold. Retest the unanswered probes and verify the authoritative DNS service, query type, and record only if failures persist.
These results describe this distributed test only and do not establish long-term availability, security, or a root cause.
