I pick it from rpd list  because I do not think it's the right place
to discuss it ... I'll appreciate if people can express share their
opinions on points below and eventually share their experiences.

Let us be completely honest, IPv6 is necessary – and we all have to get there – it’s not an option – v4 simply doesn’t scale to global needs. But – instead of these meaningless platitudes about how everyone should go to IPv6 – how about we start openly and honestly talking about the challenges with IPv6 and how we address them – so that we can promote its deployment through proper understanding – and instead of everyone going “lets all move to ipv6” – let’s start finding solutions to some of the things that STOP people moving to IPv6.
> 1. Lack of legacy support in a fair ton of hardware – how do we deal with it
> 2. Vastly inconsistent support for transition mechanisms and chronically bad support for most of these transition mechanisms in CPE’s
> 3. The complete *mess* that MPLS support as concerns IPv6 (to this day you cannot do vpnv6 without a v4 underlay, martini is entirely bound to LDP and LDPv6 support is near non-existent, and I’ve yet to see Kompella working entirely without v4 in some form either)
> 4. The security challenges around IPv6 and the bad implementations that create issues here – issues which over the years we have learnt to deal with in IPv4 – Happy to expound on these off list – and no – they have nothing to do with NAT or the lack thereof – because NAT as a security mechanism was the biggest lie ever sold to an industry.
> For years I have been an IPv6 advocate – and I still am – and I’ve actively deployed and run IPv6 in production supplying it to the end user, with multiple percentage point changes in country IPv6 penetration statistics as a result, but I am fast realizing that if we want IPv6 to grow and thrive – it’s time we started being a little more open and honest about the challenges and problems with it – instead of sprouting off that everyone should just move to it. Let’s acknowledge that IPv6 is critical, we have no option, but it is also deeply flawed, has major problems, and until start dealing with those – we will see deployment continue to stutter
