CNNICs Mission on Address Management
  • From the perspective of a NIR, CNNIC values the
    following targets
  • Address Aggregation
  • Address Administration
  • Allocation
  • Renumbering
  • Statistics
  • Address Authentication

IPv4 Address Management in China
  • Feedback from MIIT and ISPs
  • Lack of statistics information
  • For governance
  • For ISPs
  • Inefficiency
  • Manual configuration
  • Address block number and BGP entries
  • The idleness of address
  • User Identity Management
  • Billing
  • Customization

7
IPv6 Address Management in China
  • The more organizations, the more complicated
  • IPv6 brings some new features, providing some
    solutions to the above problems
  • Stateless address auto-configuration
  • Prefix Delegation
  • ID/locator split
  • Portable address

Address Management Structure
  • Internet governance
  • NIR LIR
  • Request IP address from RIR
  • ISPs
  • ISPs get IP addresses from NIR LIR
  • Downstream ISPs
  • Access network
  • Terminals
  • Get IP addresses from upstream

for Governance

For ISPs
Automatic address block management

For Access Network
Authenticated and Trustworthy management

GAP Growth-based Address Partitioning

Renumbering Overview (RFC 4192)
  • Plan for the renumbering process
  • Develop a new addressing plan
  • Prepare address assignment and DNS
  • Configure network elements with the new prefix
  • Modify ACLs, filters and other security
  • Assign prefixes to links and addresses to
    interfaces
  • Add new prefixes to routing infrastructure
  • Configure hosts with addresses of new prefix
  • Transition from use of the old prefix to the new
    prefix
  • Remove the old prefix

19
CNNIC-Cisco Addressing Research Lab
  • Focus on network addressing-related research
  • address allocation
  • address management and administration
  • address identification
  • address security
  • IPv6 addresses
  • To identify potential issues and provide
    solutions for the next generation internet.
