We provide some anycast services
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.
