Longest Match / Organisations

Organisations

Who address space is registered to, ranked by how much they hold. The 5,000 largest of 89,919 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. Holders come from the bulk whois RIPE, APNIC and AFRINIC publish, so North and South American holders are largely missing.
