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,
