Are there any security risks with using a public IP address though? I also use EduRoam at a Dutch university, should I treat it as sceptically as a coffee-shop WiFi? (Assuming it’s marked as a public network). Also, shouldn’t your university’s firewall stop such a Logitech driver sending data (if it’s an uncommon port)?
After reading up about public IP addresses I realised that my (Dutch) ISP has also provided me a public IP... and that the Netherlands has a lot more IP addresses per capita than most European countries.[1]
Most ISPs in Western companies will hand out public IPs because they were bought when they were cheap.
The danger associated with public IPs is not that high as long as you use software that binds to localhost instead of 0.0.0.0 for network services or use a firewall on your PC. The problem is that many software developers don't expect end user devices to be reachable from the internet so security practices are sometimes lax.
