Where to Request IP Addresses?

• 1. From your upstream ISP– Receive an assignment or sub-allocation– Address space is non-portable

• 2. From CNNIC– CNNIC member– Address space is portable

• 3. From APNIC– APNIC member– Address space is portable

17

IPv4 Address Allocation Policies

• Policies for IPv4 address space management in the Asia Pacific region– http://www.apnic.net/docs/policy/add-manage-

policy.html

• All IPv4 address allocations are made according to demonstrated need under a consistent set of policies.

• It is fair to every economy and organisation.
