Where to Get IPv6 Addresses
Contact a local ISP or the Regional Internet Registries below
ARIN - American IPv6 registration services
APNIC- Asia Pacific Network Information Center
RIPE - European Regional Internet Registry
The amount of addresses allocated varies according to your network
requirements. Small Internet Service Providers (ISPs) or end nodes
acquire IPv6 addresses from their upstream provider. Large ISPs, for
example can receive from ARIN a minimum prefix of /48 with a
second-level allocation of 16 bits for subnets. The remaining 64 bits are
for a network interface
For Development Networks, contact the 6bone (www.6bone.net). The
6bone provides a testbed for deployment of IPv6.
IPv6 Address Formats
IPv6 addresses are 128-bit entities. IPv4 addresses are 32-bit addresses
normally written as four decimal numbers (dotted decimal), one for each
byte of the address.
Example: 192.1.2.34
IPv6 Node Addresses are 128-bit records represented as eight fields of up
to four hexadecimal digits. A colon separates each field (:). Example:
3ffe:ffff:101::230:6eff:fe04:d9ff.
