This endpoint returns every prefix currently served by the OpenCache fleet — the union of networks[] from every appliance snapshot, with duplicates removed. Content providers use it to map their traffic-steering platforms onto the prefixes OpenCache will actually answer.
Appliances publish a snapshot on change, or at least hourly. By default the list is supernetted — adjacent and covered prefixes are collapsed into the smallest covering set (10.0.0.0/24 + 10.0.1.0/24 → 10.0.0.0/23), which covers exactly the same address space with far fewer entries. Pass supernet=false for the raw serving set exactly as announced (no /24 normalisation, no aggregation). A successful call returns immediately with the full set; there is no pagination.
