#2> This website demonstrates IP address geo-location by passively measuring TCP/IP round-trip times of web requests made to a few servers spread around the world.
I don't get how that could be called passive. This is making your browser issue requests or am I missing something?

I believe the author's point was you could determine the location by monitoring other applications and their network calls.
That being said, I highly doubt there are many requests being made to Bangalore, India and this appears to require requests to a wide array of locations all over the world.

Not passive at all, as it loads content from different sources. Plus the circles are all over the place without any logic.

I agree passive is a bit odd phrasing. Though, with how many 3rd party assets websites load nowadays, I suspect this could be done without introducing any additional requests by passively monitoring the already-existing 3rd party requests.

#6Smart, but I don't know how granular you could get unless you had known servers at every possible datacenter.

#7Am I looking at the area in which the majority of circles intersect, a la Venn?

Just use a CDN with decent edge coverage. I'm sure those results can be improved drastically.

I think the author means passive in a way that no known geoip DB is used.

#10The ping times seem sensible, but I can't work out any correlation between them and the map. Just seems like a random collection of circles...
