Built for network operators, indexed for everyone

A clean read of the global routing and registry layer - without the spreadsheets, the WHOIS chains, or the dead links.

Global allocation map

Equal-area choropleth of every IPv4 and IPv6 allocation, colored by registry. Drill into any country.

Transfer activity

Daily diff against the RIR transfer logs. Inbound, outbound, and net flow for every organization and country.

Peering footprint

CAIDA AS-Rank + PeeringDB combined: customers, providers, peers, IXes, and facilities for every ASN.

API-first

Every page is a thin client of the same OpenAPI 3.1 endpoints. JSON-LD baked into the HTML for AI agents.

Daily snapshots

The five RIR delegated files, the transfer logs, and CAIDA refresh on a daily cadence. History kept, not overwritten.

Source-of-record

Every datapoint links back to its registry, version, and ingestion timestamp. No black-box scraping.
