I believe it would be informative if we assembled some statistics about the current state, ie. how many probes would get what kind of tags if we applied them today. Perhaps Max already has some up his sleeve?
Here's a quick-and-dirty answer to this: what the tags could look like if we applied them. This is about the ~12K connected probes, which collectively have ~23K resolver entries. Note: in this experiment the "more specific tags win", i.e. if quad1 is applied, then outside-asn tag is not. 6718 system-resolv-v4-private 4502 system-resolv-v4-inside-asn 2834 system-resolv-v4-google 1247 system-resolv-v4-outside-asn 1020 system-resolv-v4-loopback 933 system-resolv-v4-quad1 338 system-resolv-v4-quad9 31 system-resolv-v4-1-24 1745 system-resolv-v6-inside-asn 968 system-resolv-v6-ula 560 system-resolv-v6-loopback 473 system-resolv-v6-quad9 461 system-resolv-v6-google 335 system-resolv-v6-outside-asn 319 system-resolv-v6-linklocal 187 system-resolv-v6-quad1 Cheers, Robert
