Commonly used IPv6 networks

By ungleich

Assuming that you have a /48 per location/site, there are some specific /64 sub networks that we usually use at ungleich.
As an example let's take 2001:db8:a::/48, then the we often use these networks:

Network Description
2001:db8:a:cafe::/64 LAN network
2001:db8:a:7ea::/64 2nd LAN network
2001:db8:a:b00::/96 Incoming NAT64 prefix: mapping IPv4 islands: 2001:db8:a:b00::192.168.1.1 is IPv6 reachable
2001:db8:a:c001::/96 Outgoing NAT64 prefix: mapping the IPv4 Internet, allowing IPv6 only hosts to reach the IPv4 Internet
