If a sextant.gg host appears in your log

A sighting is one read of your server's publicly visible status: whether it is online, the player count where the game protocol reports one, and the round-trip latency. Nodes take up to twelve sightings an hour per server, rate-limited per host.

A probe sends no game traffic beyond what the game's own client uses, and never scans ports other than the one your server publishes. Where reading the player count requires signing in — Lineage 2 reports it on the login server list — the probe uses one dedicated account that logs in, reads the list, and disconnects without ever entering the game world. Its name is shown to server owners in their dashboard, not here; allowing it is what makes a listing Ranged instead of merely Sighted.

If you run a server and do not want it measured, write to nodes@sextant.gg from an address on the server's domain, naming the host. We stop probing within 24 hours.

An unmeasured server can stay listed, but its figures become the owner's own numbers and the listing says so — the dead reckoning class. We never present a claimed figure as a measured one.
