IPv6 Website Speed Test Test Findings for zztool.cc
- Tested
- Aug 24, 2026, 1:39 AM
- Completed probes
- 94/94
- Valid IPv6 HTTP response probes
- 30 (31.9%)
- Average IPv6 total response time
- 2278 ms
In this IPv6 HTTP test, the response rate for target zztool.cc was 31.9%, far below expected, with significant variation among carriers. No clear anomaly was found, but the low response rate warrants attention.
zztool.cc IPv6 speed test performance by network
Valid IPv6 response rate counts probes with an IPv6 HTTP status and total response time. P50 is the total time at or below which half of valid responses completed.

Key findings
- The overall IPv6 HTTP response rate was 31.9%, with only 30 out of 94 test nodes returning valid HTTP status codes; 64 nodes did not obtain a valid response.
- Carrier response rates varied: mobile highest (45.2%), telecom next (35.5%), unicom lowest (16.1%), and overseas nodes had no response.
- All valid responses returned HTTP 200 status, but response times were high, with an overall average of 2278 ms and p95 of 4454 ms.
Improvement recommendations
- The IPv6 HTTP response rate is 31.9%, below the 95% review threshold. Retest failed probes and verify the AAAA record, IPv6 route, firewall, and CDN or origin IPv6 support only if failures persist.
- China Unicom trails China Mobile by 29.1 percentage points in response rate. Retest both groups with the same probe set, then investigate the affected network or endpoint only if the gap repeats.
These results describe this distributed test only and do not establish long-term availability, security, or a root cause.
