IPv6 Course part 2: Stable IPv6 addresses on the local network
For IPv6, Network Address Translation (NAT) not provided. Rather, it is among other Purpose IPv6, NAT to make it unnecessary. The corollary, principle that every computer has a publicly accessible IPv6 (However, the protected by the firewall or in the FritzBox. is blocked). It also means, that by default, change the local IPv6 is, if the public IPv6 change.
Also: If you have no fixed IPv6 subnet (and perhaps reasons of anonymity and will not have), then change the default, IPv6 addresses of all computers in local network accessible, if the router gets a new IPv6 subnet. Get the router using 6to4 tunnels are IPv6 subnet, then changes the IP every time IPv6, if the router gets a new IPv4.
In the local network but it can be useful, always use the same subnet. A local server can be configured in a manner, to only accept connections from that subnet. When the Web server is the apache for example with the following commands (“Ababa:Ababa:Ababa” replace the self-chosen prefix, see following paragraph):
deny from all
allow from fd00:abab:abab:abab:/64 192.168.178.0/24

IPv6 Course part 1: Activation and basics
Any computer on the Internet is assigned a number. But are the currently used Internet Protocol Version 4 (IPv4) maximum 4 Billion. (2 high 32) Numbers available. Because they can be exploited but not to the last point perfectly, These numbers are running out. Therefore it is now gradually the new Internet Protocol Version 6 (IPv6) introduced, the more numbers provides as grains of sand all over the world.
I have learned in recent days it very difficult to IPv6. Thus, the other goes faster, I sum up this course together like chapters in a number of my knowledge. Today I start with the initial: The principles and enable IPv6. Basically, I am counting forward IPv4 knowledge.
