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::/64 The network 0 is usually internal
For netboot, untrusted equipment. Usually firewall for none incoming traffic at all
2001:db8:a:a::/64 DNS network: houses DNS servers in the network.
Regular DNS servers are usually 2001:db8:a:a::a and 2001:db8:a:a::b
DNS64 enabled servers are usually 2001:db8:a:a::64 and 2001:db8:a:a::65
2001:db8:a:bee::/64 LAN network: usually wifi/coworking
"bee" is something people can easily pronounce
2001:db8:a:cafe::/64 LAN network: usually wired/regular clients
2001:db8:a:7ea::/64 LAN network: Usually 2nd wifi 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
