I believe the best site for finding top-level domains and their associated Regional
Internet Registry is maintained by the Number Resource Organization (NRO), which
was formed by the five RIRs in 2003 "to formalise their co-operative efforts." The site
includes a great deal of information about the RIRs, including a chart of each country
and its associated RIR. RIPE also provides such a list.

The Ipv6 Transition
The current Internet addressing system uses IP version 4, and has for more than 20
years. However, the transition to IP version 6 (IPv6) is underway, especially in
Europe and Asia.
The Internet Corporation for Assigned Names and Numbers (ICANN), the
independent body that coordinates the Internet's address system, announced in July
2004 that IP version 6 (commonly written IPv6 and referred to as the "next
generation" IP addressing system) , has been added to the Internet's root server
system. Vincent Cerf, an Internet "founding father" and a member of ICANN's board
of directors, made the announcement at ICANN's annual meeting in Kuala Lumpur,
Malaysia.
In practical terms, what does the addition of IPv6 mean? Today there are still only
13 root domain name servers that contain the master records for all Internet
address mapping.
