Who address space is registered to, ranked by how much they hold. The 5,000 largest of 89,970 are listed; the search box covers all of them. IPv4 is counted in addresses and IPv6 in /64 networks, and the two are never added, because no unit makes them comparable. Registered holders come from the bulk whois that RIPE, APNIC and AFRINIC publish. ARIN and LACNIC do not publish theirs, so space held in North and South America is largely unattributed here.
