Most common responses

• IPv4 is running out, so what?
• We cant sell IPv6 / No customer demand
• Only Few Vendors support IPv6
• Only Few Application support IPv6
• Nobody uses IPv6, so why bother?
• We can still use NAT
• Migrate to IPv6 is too expensive!
• (No Easy Return of Investment)

IPv4 is running out, so what?

• Does The Internet will stop working? (remember
  y2k issue?)
• Does your current Internet application will stop
  working?
• But.
• Can your network grow larger?
• Can you have more IPv4 when you need them?
• Can your network access the new networks of IPv6?

4
We cant sell IPv6

• Does anybody sell IPv4?
• IP address is not a property
• Neither IPv4 or IPv6 can be bought or sold
• What we sell is Internet connectivity Services.
• IPv6 enables us to continue providing Internet
  connectivity Services to our new and existing
  customers.

Nobody Use IPv6, why bother?

• There are some ISPs in China that received only
  IPv6 allocation.
• Google has start migrating to IPv6
  (http//ipv6.google.com)
• NTT OCN IPv6 Services
• Arch Rock
• IPv6 Network is growing around the world
• Its not growing as fast as IPv4 because some
  people just wait and see

NAT Problem
9
IPv6 Migration is expensive!

• Dont have to upgrade all at once
• Plan your transition carefully
• Secure monthly budget
• It can be expensive if youre too late.

10
IPv6 is not an extension of IPv4

• Transition mechanism needed
• Dual Stack ? best practice
• Tunneling ? a great way to start
• NAT-PT ? bridging IPv4 to IPv6 communication
• in practice, you'll want to maintain ipv4
  compatibility during the IPv6 transition period.
• You can use more than one mechanism.

11
Other Facts

• Internet is growing rapidly ? internet banking,
  mobile phone users.
• IPv4 wont be sufficient to sustain Internet
  growth
• Something need to be done
• NAT has its own problems
• IPv6 is happening around the world ? China (IVI),
  Japan, Korea, Malaysia, Europe countries
• IPv6 implementations still have some issues as
  any new technology have

12
IPv4 Black Market

• Impact on routing table size
• Larger routing table size ? router must be
  upgraded
• Cost for router upgrade
• Cost for buying IPv4 from other ISP.

13
Upgrading to IPv6

• Request for IPv6 allocation from your ISP or
  directly from APJII/APNIC.
• Make an inventory of your current network
  equipment.
• Decide what transition methods works best for
  your company.
• Add IPv6 enabled featured as future procurement
  criteria
• Secure monthly budget for upgrade/training

14
Experiencing IPv6

• You need to have a global routable IPv4 address
  on your router interface.
• Sign in at a tunnel broker (its free), eg
  www.tunnelbroker.net
• Click Create Regular Tunnel
• Input your global routable IPv4 address
• Select your router type, you will get the
  configuration needed for your router.
• Setup 6to4 interface on your router using the
  configuration provided.
• Time needed 5 to 10 minutes

Conclusion

• IPv6 Transition is necessary to anticipate
