The addressing structure is as follows: IPv6-only, DNS64/NAT64 for IPv4 connectivity is applied at the edge or/and translated as neccessary, for egress, for instance. The infra uses fdab::/8 as the internal and primary address range. This is to be autonomous from organizations (like RIPE), goverments and the public internet. The adressing structure can be described by the following example: fdab:0001:000a::4 ^ ^ ^ ^ | | | | | | | | - - -|- - | - - | - - The prefix for all adresses | | | | | | - - | - - | - - The site identifier | | | | - - - | - - The vlan identifier | | - - - The host part Please note that the address above, for demonstrative purposes, is not properly written and the correct form would be fdab:1:a::4. The following site identifiers have been assigned: 0001: pasta-home The following vlan identifiers have been assigned: 000a: vhost-mgmt Every network is a /64. The gateway for every network is its first address. The gateway also does DNS. For example, in the case of the vhost management vlan in pasta's home, the gateway would be fdab:1:a::. With egress traffic, the WAN Addresses (when viewed from the internet) are not defined and will change without notice. Don't rely on them. Tips: ===== Use ping6 instead of normal ping. Some distributions/os don't support IPv6 in normal ping. The NAT64 prefix is 64:ff9b::/96 -- the DNS resolver will return translated records for domains that only have an A (IPv4) record. To reach IPv4-Addresses directly, please embed it into the NAT64 prefix, i.e. 64:ff9b::167.235.227.83. 464XLAT could be used if IPv4-connectivity is *really* required for software running on the machine. Usually its not needed.
