Verification of the NAT64 setup type for RIPE Atlas probe ID 11149

Ascertain whether RIPE Atlas probe ID 11149 is operating within a custom local NAT64 setup or using an ISP-provided NAT64, given that the round-trip time to the NAT64 was below 2 ms but available information was insufficient to confirm the configuration.

Background

The authors use two tests to classify whether NAT64 deployments are ISP-provided or locally configured. Test 2 relies on the round-trip time to the NAT64, with very low latency suggesting a local (home) setup.

Among five probes identified with RTT < 2 ms, three were likely custom setups, one was likely an ISP setup close to the NAT64, and the status of probe 11149 could not be confirmed from available data, leaving its classification unresolved.

References

We could not verify whether the fifth probe (ID 11149) is a custom setup.
