Network trust findings
Among the largest organisations in our index, these show netblocks registered to them but cryptographically authorised (RPKI ROA) for a small, specific set of unrelated networks — often M&A history, multi-homing, or outsourced/managed hosting relationships that WHOIS data alone can't surface. Large wholesale/transit carriers whose address space is diffusely re-announced by many downstream customers (normal business, not a specific finding) are deliberately excluded — see Data & methodology.
