Holding a block is a registry fact, not a physical one. The organisation named here is who the block is assigned to, which is often a customer of the network operator announcing it.

Every figure on this page is also JSON: /api/v2/directory/org/blackbridge-limited. Breakdowns paginate from there, so a table showing the largest rows here returns all of them. Read the API.
