Lumeta Corporation created this map of the iPv6 internet using data collected on Feb. 5, 2009. each end node can represent a handful of computers on a small network, or perhaps a large company with hundreds of thousands of hosts. ( http://www.lumeta.com/iPv6/)

erator of what was and still is called
the IANA (Internet Assigned Numbers
Authority). IANA historically allocated
large chunks of address space to end
users or, after the commercialization
of the Internet, to Internet service
providers (ISPs). With the creation of
the Regional Internet Registries (for
Internet addresses), IANA typically al-
located 24-bit subsets of the IP address
space (sufficient for 16 million hosts)
to one of the five regional registries,
which, in turn, allocated space to ISPs
or, in some cases, very large end us-
ers. As this article was being written,
ICANN announced that it had just allo-
cated the last five of these large 24-bit
chunks of space.
