   Initial concepts.
   Why IPv6?
   IPv4 Runout Policies.
              Some initial concepts.

   IPv6 is the evolution of IPv4, the most successful
    network protocol of the history.
   IPv4 and IPv6 are not “compatibles on the wire”, which
    means an IPv4 only host can’t communicate with an
    IPv6 only host by itselves.
   IPv6 will not substitute IPv4, both protocol will co-
    exists for several years. Just like IPX is still existing in
    your networks. There won’t be an “IPv4 Blackout”.
                 IPv6 Advantages

   Many more addresses:
    340,282,366,920,938,463,374,607,431,768,211,456 available addresses.

   It makes simpler IPv4 tasks:
          Auto-configuration.
          Renumbering.
          Security (IPSEC).
          Multicast.
          IP Mobility.
   Innovation.
   Efficiency.
            ¿Why do we need a new network
            protocol?

We need more addresses!

    Thousand of millons “always on” users.
    More divises to connect: cell phones, PDA, games
     consoles, etc.
    New applications: Home control, sensor networks.
    New broadband technologies: Wimax, DOCSIS 3.0,
     etc.

             IPv4 Run-out

   IPv4 has 4.3 billons available addresses.
   Initial allocations did not considered the success of
    the network.
   In the early 90s there was already fear about the
    run-out of IPv4 addresses and worked started on a
    successor.
   In 1993, CIDR arrives and then NAT. The end of IPv4
    gets postponed.
                    IPv4 Run-out. The plan 10 years Ago.

From Geoff Huston - RIPE 56.
             ¿What happened then?



   Thanks to CIDR and NAT the network grew without
    needing IPv6.
   The industry did not invest in IPv6.
   2000 crisis?
   So, IPv6 did not flied.
         So, ¿What is the problem now? (1)

                            addresses space.
              What could happen?

   There will be IPv4 addresses for many years. (in
    different ways).
   Difficulties for allocating big (and not so big)
    contiguous blocks.
   IPv6 could not be broadly used until IPv4 is exhausted
    or until there are adequate economic incentives.
   At some point, there could be “only IPv6” users.
   NAT Use Increases
   Secondary/Gray Market
                  Carrier Class NAT.

             Reflections

   IPv6 will not replace IPv4 neither in the short term nor
    in the midterm. Both protocols will coexist for many
    years.
   The policies for receiving IPv6 addresses are not an
    obstacle. Neither the associated costs. They aim to
    facilitate IPv6 adoption.
   IPv6 is ready for its utilization. As any other technology,
    it is something live that will be improved along the time.
    But it is ready.
   Many efforts should be focused in promotion and
    training.
   It is also a very good opportunity for innovation.
                  Policy discussion

   There are several proposal being discussed in the RIRs’
    open policy forums.
        To encourage adoption of IPv6
        For facilitating the transfer of IPv4 addresses between organizations.
        For distributing one part of the remaining unallocated pool.
        For ensuring IPv4 addresses to new entrants.

   Any adopted or rejected proposal has impact in our
    communities, and in your businesses.

   Participation is very important.
        Information about how to participate in LACNIC policy development
         processes is available in the website.
            Scenarios

   Different possible scenarios based in what
    measures are taken and what policies are adopted.
   It is not possible to ensure that the access to IPv4
    addresses in secondary markets (grey markets) will
    be equitable.
   There are a lot of things to do, but the most
    important is to work in IPv6 deployment and
    adoption.
