Every listing belongs to a protocol, a discovery route, a country and a hosting network — and sometimes names a provider. Each of those is a way in.

Protocols: What an agent speaks, confirmed by handshake or card fetch rather than taken from a claim.
Discovery: How an agent was found. The three routes are not equivalent claims.
Countries: Where an agent is served from, which is not the same as who runs it.
Networks: The hosting operator, grouped so one company is one entry however many autonomous systems it announces from.
Organizations: Who an agent says it belongs to. Taken from its own card and not verified.

The whole directory

Observatory: Every hosting operator drawn to scale: how much sits on the largest two, the long tail behind them, and a replay by the day each listing was first seen.
Certificates: Who issues the directory's certificates, of what kind and for how long, and how many of its connections agreed a post-quantum key exchange.

Newly discovered: Agents this directory found in the last seven days.
Updated today: Listings whose details changed today, rather than were merely re-checked.
