We provide some anycast services over IPv6.

Anycast address space

fd42:d42:d42::/48 is reserved for anycast services.

Each anycast service runs on a dedicated /64 in this range. This way, nobody needs to update filters.

Remember, if you announce an anycast /64, then you need to provide all services within this /64. It's probably simpler to only provide one service for each /64.
