Probes with IDs less than 6000 are the first generation (v1) probes:
https://atlas.ripe.net/docs/probe-v1/
They have limited processing power, and have higher latency with any
kind of network measurement, including DNS. This limitation is mentioned
here:

I hope this helps you to understand what you're observing.
