In such a world you can say goodbye to any kind of free Wi-Fi, anonymous proxy etc., since all it would take to burn an IP for a year is to run a port scan from it, so nobody would risk letting you use theirs.
Fortunately, real network admins are smarter than that.
Pretty much. I think there's also a responsibility on the part of the network owner to restrict obviously malicious traffic. Allow anonymous people to connect to your network and then perform port scans? I don't really want any traffic from your network then.
Yes, there are less scorched-earth ways of looking at this, but this works for me.
As always, any of this stuff is heavily context specific. Like you said: network admins need to be smart, need to adapt, need to know their own contexts.
Do you feel coffee shop WiFi should require you to scan your passport to connect, or that it shouldn't exist at all?
Not OP, but the latter sounds pretty good actually, yeah. Never understood the free WiFi craze anyways. Just use cellular?
Not all of us have cell plans with hotspots ($$$), hotspots often have data caps, cell is often slower or congested, and there are some areas without cell signal. It's also kind of silly from a wider perspective to shove everyone onto the cellular network when most businesses have perfectly decent fiber internet nowadays.
Sure, I'm usually on hotspot, but I personally appreciate when businesses have wifi. Either way, there are always going to be shared networks somewhere.
And you should require your passport to get one of those?
