| Netherlands | 100% | 100% |
Organisations holding assignments here
Registered organisations account for 97% of this network's IPv4 space and 100% of its 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 ARIN and LACNIC do not publish theirs, so space held in North and South America is largely unattributed here.
| Organisation | IPv4 share | IPv6 share | |
