 | 
					Recently
 | 
				
			||||||
 | 
					Apple decided to [remove a central
 | 
				
			||||||
 | 
					app for communication in Hong
 | 
				
			||||||
 | 
					Kong](https://www.bbc.com/news/technology-49919459), just
 | 
				
			||||||
 | 
					[to add it later
 | 
				
			||||||
 | 
					again](https://www.bbc.com/news/technology-49961149).
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					With this move Apple effectively disrupted the communication between
 | 
				
			||||||
 | 
					people demonstrating in Hong Kong and at the same time endangered
 | 
				
			||||||
 | 
					those who wanted to protect themselves from violance on the streets.
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					In this article I want to show how this problem can be mitigated by
 | 
				
			||||||
 | 
					the use of IPv6.
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					## The core problem: centralisation
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					The main problem is that we depend on centralised
 | 
				
			||||||
 | 
					services. One of the questions is, why do we depend on centralised
 | 
				
			||||||
 | 
					services at all? The reason for this is that there are not enough IPv4
 | 
				
			||||||
 | 
					addresses and for that reason we use NAT to hide multiple devices
 | 
				
			||||||
 | 
					behind one IPv4 address. Wait what? Let's take it a bit slower.
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					## How NAT works
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					In the old times of the Internet, every device in the Internet used to
 | 
				
			||||||
 | 
					have a public IPv4 address. However when the number of devices began
 | 
				
			||||||
 | 
					to exceed amount of officially available IPv4 addresses, NAT was
 | 
				
			||||||
 | 
					introduced and it works as follows:
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					Many devices are hidden behind one Public IP address. So for a phone
 | 
				
			||||||
 | 
					to communicate with another phone, it needs to connect via a
 | 
				
			||||||
 | 
					central, publicly available IPv4 server.
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					## How IPv6 solves the problem
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					In the IPv6 world, there are enough IP addresses available.
 | 
				
			||||||
 | 
					So every device, every smart phone, every alarm clock, every computer
 | 
				
			||||||
 | 
					can have a public IP address. Because every device can have a public
 | 
				
			||||||
 | 
					IPv6 address, they can communicate directly with each other:
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					## How to communicate with IPv6?
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					So how does it look like with IPv6? Instead of relying on a central
 | 
				
			||||||
 | 
					entity (Apple in this case), you can directly connect to the phone of
 | 
				
			||||||
 | 
					your friends. This way, you could even use your standard browser like
 | 
				
			||||||
 | 
					Firefox, Chrome or Safari to write a message to your friend's phone.
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					## So, what to do now?
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					At the moment IPv6 is picking up pace in deployment and ISPs
 | 
				
			||||||
 | 
					everywhere in the world are moving forward with it. However, if you do
 | 
				
			||||||
 | 
					not have IPv6 connectivity, we [provide IPv6
 | 
				
			||||||
 | 
					VPNs](https://ungleich.ch/ipv6/vpn/) that enable you world wide to
 | 
				
			||||||
 | 
					have IPv6.
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					## More IPv6
