They're static and used exclusively by Prerender.io.
Our EU cluster may also send requests using IPv6, here are the current aggregated ranges:

These subnets could be shared with our vendor's other customers.
We have a mix of servers in the US and Europe. Paid customers can request rendering from our US cluster only if you don't want to permit IPv6 subnets from your side.
