When one connects to a public network, one's device is
typically provided with a Local IP address and a pair of DNS
(Domain Name Server) IP addresses.
Public networks such as WiFi at Universities, Airports,
Hotels, Doctor's offices, Hospitals, Libraries, Coffee
Shops, etc. ARE NOT SECURE. Any computer on those networks
may have malware harvesting EVERYTHING you say, type and
read. WiFi in retirement communities and apartment complexes
may also be public networks. Find out!
See what devices are on the network you are currently on:
Mac: LanScan
iPhone/iPad: Net Analyser Pro
In order to protect your privacy (and security) on a public
network you should:
1. Use a VPN (Virtual Private Network)
2. Use Public DNS (Domain Name Server)
