Hi all,

I was wondering if anyone managed to come up with a method of getting a
probe selection via the API that is based on city. The web interface
allows this, by searching for "place", which is subsequently handled by
the Google Maps API (I think), and which then comes back with a number
of probes on the map, in that given place. However I need this in the
API, which only allows to select probes based on "area, country, prefix,
asn".

What I'm currently trying to come up with is a way to map, more or less,
onto the list of ICANN specified probing locations for their DNS tests.
This list is published here:

https://tld-monitor.icann.org/nodes.csv

I've been trying to go by the ASNs that the listed locations have their
IP space in, but that frequently gives me a negative result (no probes
present). The same for the prefixes themselves, of course. And just
going by the enclosing country code is fine for a small place like
Luxembourg, but not for a big country like Canada.

So if anyone has any ideas on how to achieve this in a dynamic way (so
as not to have to manually build and maintain a list of probes), I'd be
very interested in hearing about that.

Thank you,

Paul Vlaar
