Organisations holding assignments here

Registered organisations account for 97% of these networks' IPv4 space and 100% of their IPv6 space. The table below divides that space. 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 ARIN and LACNIC do not publish theirs, so space held in North and South America is largely unattributed here.
