Other maps draw the plumbing — who announces which addresses. This one draws occupancy : which addresses host the nameservers and websites of the domains in 1,074 top-level zones, who runs them, and where. Read every day from the zone files. Nothing is scanned.

If one network vanished, what share of the domains we can fully see would go dark? A domain counts only when every one of its servers sits in that network.
Nameservers Web
Honest by construction. Network and country are who announces a block and where it is registered , never where a server stands. A location is shown only when a cloud provider publishes one region for every occupied address; anycast and global ranges are “not a place”. Counts are domain–prefix incidences. No address is ever probed: everything comes from zone files, the census's own resolution, and public routing and registry data (iptoasn PDDL, the five RIRs, providers' published ranges).
