1. Overview

This document details the address space managed by the RIPE NCC and
the longest prefixes allocated or assigned from different address
ranges.

2. Special Purpose Ranges
2.a. Internet Exchange Points

Small IPv6 blocks have been assigned to Internet Exchange Points
(IXPs) under the IPv6 Address Space Policy for Internet Exchange
Points (ripe-256). All IPv6 IXP assignments come from the
2001:07F8::/32 range and are registered in the RIPE Whois Database. A
full list of IPv6 IXP assignments can be obtained by querying the RIPE
Whois Database for all more specific inet6num objects. This can be
done on the RIPE NCC web site at:

http://www.ripe.net/whois?-rm+2001%3A07F8%3A%3A%2F32

It is possible to create a list of the IP ranges assigned by the RIPE
NCC with a command line query like this:

$ whois -h whois.ripe.net -r -m 2001:07F8::/32 | grep ^inet6num

2.b. Root Name Servers

IPv6 blocks have been assigned to Root Name Servers under the IPv6
Addresses for Internet Root Servers in the RIPE Region policy
(ripe-233). These assignments come from the 2001:7F8::/29 range and
are registered in the RIPE Whois Database.

2.c. Address Space Used by Networks in Africa

Between October 2003 and April 2005, IPv4 allocations and assignments
to Local Internet Registries (LIRs) and End Users in African countries
north of the equator were made from 196.200.0.0/13. This range was
part of a /8 also used by the American Registry for Internet Numbers
(ARIN) for African allocations. Because the longest prefix ARIN
allocated or assigned for 196/8 was /24 this was also the longest
prefix the RIPE NCC assigned from 196.200.0.0/13.

3. Routing Decisions

Routing decisions are the responsibility of network operators. Network
operators taking routing decisions based on prefix length are
requested and encouraged to route blocks of sizes corresponding to the
longest prefix.

[2] 2A01:0000::/16 was allocated in December 2005 incorporating the
    previously allocated 2A01:0000::/23.
