Hi mp,

This is a great idea.  I hypothesise that:

(1) People have no idea how much data they are sending to online services;

(2) People have no idea how often their various devices (not only PCs and
smartphones but also 'internet of things' devices) send data, even when the
user is not actively using them; and

(3) People have no idea how often routine activities such as web browsing to
ostensibly unrelated sites, email checking, and so on result in telemetry being

And of course, people might not realise that their physical movements and the
cadence of their activities over time are part of the accumulated data set.

I'm surprised that the Google prefixes are hard-coded.  Suggest using the
updated prefixes from the global routing table instead.


(replace with whatever date is today)

Download and unpack the five files in this directory.

Inside you will find a file 'data-used-autnums'.  You can search this file for
the names of autonomous systems (networks), or 'ASes', that together comprise
the Internet.

You can search this list, e.g.:

$ grep " GOOGLE" data-used-autnums

Let's not single-out Google.  Indeed you can look for other possible offenders
too, e.g.:

$ grep " MICROSOFT" data-used-autnums

The first column of the results are the AS numbers.  There is another file,
'data-raw-table', which maps the numbers to prefixes.  You can use this file to
identify all of the prefixes you want to examine.

$ grep -w 15169 data-raw-table

I hope this helps.

Happy hacking,
