Map of the Internet

How the Sites map is drawn

Every point is a domain from the Common Crawl hyperlink graph, a crawl of billions of web pages reduced to which domains link to which. The 30,000 best-connected domains are arranged by their links to each other, so sites that cite each other end up close together. Every other domain then sits beside one better-connected neighbour, preferably one it links to and is linked from in return.

Size follows the harmonic-centrality rank: how close a domain is to every other domain, link by link. Zooming in reveals smaller and smaller sites, down to the 10 millionth.

Looking for one site?

Type any domain into the search box on the Sites tab. If it is past the 10 millionth place, the map still flies to the neighbourhood it belongs in. For the full list of a domain's links, open it in theWeb Graph Explorer, and for its rank, DNS, SSL and headers, its domain report.

How the Networks map is drawn

Each dot is an autonomous system (AS): a network with its own AS number and its own routing policy, such as an ISP, a hosting company, a cloud or a backbone. Colour is the network's country. Size is the number of IPv4 addresses it announces or the number of networks that reach the internet through it, whichever is larger.

Backbones sit in the middle and each region forms its own sector. Networks with a single upstream sit on the rim. A faint line joins every network to its main upstream provider.

What the coloured links mean

Click or search a network and its links light up. Cyan leads to its upstream providers, the networks it reaches the rest of the internet through. Orange leads to its customers. Violet leads to its peers, networks that swap traffic with it as equals. Your own network has a pulsing ring.

Nobody publishes these relationships openly, so we infer them from the AS paths in the routes. We use the method published by Lixin Gao, with refinements from CAIDA's AS-Rank work. The result is right for most links and wrong for some: read any single link as likely, not certain.

How the Addresses map is drawn

All 4,294,967,296 IPv4 addresses lie along a Hilbert curve, a path that fills a square while keeping consecutive addresses next to each other. A faint line traces that order. Zoomed out, each square is a /8 of 16.7 million addresses, coloured by whom IANA gave it to: one of the five regional internet registries (ARIN, RIPE NCC, APNIC, LACNIC, AFRINIC), a company that held it before the registries existed (legacy), or nobody, because it is reserved.

Zoom in or click, and each /16, then each /24, takes the colour of the network that announces most of it. The less of a block is announced, the dimmer it is; dark means no network announces it at all. This view covers IPv4 only.

Finding a network or an address

The bar above the tabs shows your IP address, your network's name and AS number, and your country, as Cloudflare sees your request. Only you see it; we do not store or log it. Your address is also marked on the Addresses tab at every zoom level.

Networks takes an IPv4 or IPv6 address, an AS number (AS13335 or 13335) or part of a name. Addresses takes an IPv4 address. Links such as /map/#as=13335 or/map/#ip=8.8.8.8 open the same view for anyone. A block's network on Addresses opens on Networks, and the domain report of a site names the network its server is in, with a link to it here.
