Well Anycast just works by configuring the same IPv6 Address (there is no special range for Anycast) on multiple devices (most times spread over the country or world). The routers in front of the device advertise this IP address via BGP to the rest of the internet.

When you want to connect to the AnyCast IP address your ISP will go to the closest one. When that fails it is removed from the routing table and then you go to the one that is next closest.

Most of the times DNS servers are using AnyCast addresses for this purpose :).
