REPORT: Transitioning from IPv4 to IPv6

The pace to implement IPv6 will increase as the Internet Assigned Numbers Authority (IANA) stopped issuing public IPv4 addresses. This event will force the use of IPv6 for new Internet Access circuits once carriers have depleted their IPv4 allocation. MSI can participate in the IPv6 implementation as follows:

IPv4 Issues
  • Montevideo, 3 February 2011 – The Number Resource Organization (NRO) announced today that the free pool of available IPv4 addresses is now fully depleted. On Monday, January 31, the Internet Assigned Numbers Authority (IANA) allocated two blocks of IPv4 address space to APNIC, the Regional Internet Registry (RIR) for the Asia Pacific region, which triggered a global policy to allocate the remaining IANA pool equally between the five RIRs. Today IANA allocated those blocks. This means that there are no longer any IPv4 addresses available for allocation from the IANA to the five RIRs.
  •  Private Networks can and will continue to use IPv4 internally.


IPv6 vs. IPv4
  • IPv6 structural changes will force numerous changes to new and existing IP based networks to impact:
    • Addressing
    • Routing (Routing protocols / Route Databases)
    • Architecture (Topology / Connectivity)
  • Changes include:
    • Addressing (IPv4 & IPv6 coexistence)
    • Equipment Changes (not all edge equipment supports IPv6)
    • Address Translation (IPv4 ↔ IPv6)
    • Security/Firewall considerations (IPv6 offers enhanced security features)
