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.
Thanks for this quick and useful report, Robert. What I take from it is that - (a) for most of the categories of interest, the one which (most closely) matches a given probe may readily be determined, and - (b) only one category seems ambiguous with regard to Max's original question, since "inside ASN" doesn't necessarily correspond to "using the ISP's DNS server". I'm wondering whether this ambiguity matters in the context of Max's question, and reckon that his opinion on this is a significant one. For my own network, I have always the option of reconfiguring to use ULA/RFC1918 (both private) instead of GLA/RFC1918 (inside-ASN/private). Thanks again, Niall (hat off)
