Agree on these issues as listed below， with added a few, including security concern, DHCP, ... :

- Addressing issues( DHCP issue may belong to this) - DNS issues - Firewall issues - Tunneling issues - Transition mechanisms issues - Happy eyeballs issues - Why avoiding at all cost saying “if you have issues just disable IPv6” - Security issue - less supporting software/solutions, like accounting/management/trouble shooting softwares...

Thank you very much for your suggestions. What we need is to break down this areas and find actual cases and situations for each bullet above. like: "users host configures IPv6 address from RA sent from router, but there is no further IPv6 connectivity between CPE and ISP" - and the procedure how to detect that and how to fix that or: "I can get to Facebook, Google, YouTube, Wikipedia, (list other dual-stack sites) but not Amazon, eBay (other IPv4-only sites)." Troubleshooting: Try www.test-ipv6.com, what do you see there (and move forward through procedure flowchart) The main goal of the document is to push/move forward the IPv6 implementation towards end-users and this inability for technical folk to deliver a simple IPv6 description/script/information to helpdesk manager is creating psychological impediment to move things forward. For example - a fire-alarm procedures. We don't have to know how fire works, what the temperatures are, how fire extinguisher works, how the dust that comes out of it affects the flame and so on and so on... We need simple instructions "in case of fire or visible flame, go down the stairs, find red cylindrical thing on the wall, read instructions how to use it and point towards fire. If fire don't go away, call fire brigade at number XXX (second level support)" No RA,DHCPv6,PD,etc... just simple clear instructions how to determine if the problem is because of IPv6 issue, locate the issue (for example go to test-ipv6.com, what do you see... ah, in this case do [that]...) and move forward through the procedure.
