Suggested change

	Virtual Private Networks are a way of extending the end of your network to exit somewhere else in the world. An ISP can see the flow of internet traffic entering and exiting your network termination device (ie. modem).
	Encryption protocols such as HTTPS are commonly used on the internet, so they may not be able to see exactly what you're posting or reading but they can get an idea of the [domains you request](/basics/dns.md/#why-shouldnt-i-use-encrypted-dns).
