Thanks that is what I thought. So the onus is on the IP not the WiFi provider?
I would say so, yes. Because no actual content info is stored on the wi-fi equipment. No pictures, no emails, nada.
Now some providers might have proxy servers built in for caching and/or DNS resolution but my guess would be that for wireless setups like McDonalds or whatever, that’d be very few if any.
A simple 802.11 setup could easily handle the volume for a dozen or so users without even breaking a sweat, so there’s little need for that kind of equipment at a local wifi hotspot.
