The global allocation map
Hover a country for stats, click to drill in. Switch the metric or filter to a single continent.
By regional registry
View detail →Largest IPv4 concentration: ARIN (0 hosts) · most ASNs: ARIN (0) · most IPv6 prefixes: ARIN (0).
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.
