DNS Test Findings for 223.6.6.6
- Tested
- Oct 19, 2026, 9:59 PM
- Completed probes
- 74/74
- DNS response probes
- 2 (2.7%)
- Average DNS lookup time
- 2 ms
Across 74 nodes, only 2 obtained a valid DNS response, giving a DNS response rate of 2.7%, far below the 99% reference threshold. Responding lookups had a median DNS lookup time of 2 ms, but most nodes produced unanswered lookups.
223.6.6.6 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
- Only 2 of 74 nodes returned a valid DNS response, a DNS response rate of 2.7%; the other 72 nodes did not obtain a valid result.
- Responding lookups showed a median DNS lookup time of 2 ms, with P90 and P95 both at 3 ms, so timing itself looked normal.
- Unicom nodes accounted for both valid responses; other carriers supplied no comparable response data.
- Only one resolved address was observed, which reflects answer diversity in this run and does not establish that resolution was correct.
Improvement recommendations
- The DNS response rate is 2.7%, below the 99% review threshold. Retest the unanswered probes and verify the authoritative DNS service, query type, and record only if failures persist.
