(Focusing on the updates after 2008/05/30 P2 major revision)

Q:What is the latest IPv6 Ready Logo updates?

A:Starting from 2008/05/01, Phase-2 Ready Logo applications have increasing very rapidly.
  • Phase-2 Ready Logo worldwide for 2008 is 86(current total is 222)while Phase-1 is only 38(364 is the current total)
  • Most of the increasing applicants are from USA, Japan and China. For USA and Japan these applicatns are from industry and for China they are mostly acedmia。
CHTTL IPv6 Testing Lab is continuing working to promote Phase-2 for maintaing Taiwan's leadership in this Phase-2 category.We are now providing DHCPv6 Logo testing services to our Taiwan clients.

A:The new version removes the 1.7 Routing Header Type 0 test item.

Q:Can users start using P1/P2 Core version 4.0.0 now?

A:Of course. If you are not comfortable using version 4.0.0 directly. You can test run Self-Test 1.4.15 and Self-Test 4.0.1 to decide if this is the right decision to move forward。

Q:Wil Phase-1 Silver continue to exist?

A:IPv6 Ready Logo program is scheduled to phase out Phase-1 in November 2008年. But this is still under discussion.

So far Phase-2 is definitely gaining momentum. We will continue to provide Phase-1 testing services. It is really the vendor's decision to stay with Phase-1 or not.

Q:Where can we download the latest IPv6 Ready Logo test documents?

A:Please visit the follwoing URL for IPv6 Ready Logo test updates.

Q:Do you provide any IPv6 Ready Logo test training?

A:You can register for TWNIC(Taiwan Network Information Center)'s Free IPv6 Training Courses(Chinese only) to learn more about IPv6 Ready Logo testing.

Q:Can Taiwan users find the IPv6 Ready Testing Lab here in Taiwan?
