Re: End of IPv4 !!

While ARIN is a good resource and shouldn't be discounted, ARIN is
less vested in the operational aspects of IPv6 than the assignment
policies in v4 and v6. They function as a registry and have authority
as a registry but otherwise are limited in any sort of control over
the public IP domain. It should be reminded that registration of a
block within one of the RIRs doesn't guarantee that the block be
accepted by all because an RIR does not possess the authority to
mandate acceptance of a prefix.

To some degree, the operational side will be pushed by the RIRs to
move to v6 through more stringent requirements for blocks, but I have
yet to see that a registry has attempted to impose its will by
mandating a policy compliance beyond the usual proof of utilization
and verification thereof.

In that light, it should be noted that the registries have not
attempted to force folks onto IPv6 as the IPv6 internet is not
compatible with IPv4 (obvious) and would not be received well by
service providers who, at the end of the day, will do what it takes to
maintain a network most favorable to supporting the legacy IPv4
platform first and potentially migrating to IPv6. Even then, IPv6 is
gaining momentum but still considered optional, in many ways, versus
the availability of IPv4 with regard to public internet. This can be
seen by the general lack of native IPv6 services (read: IPv6
connectivity at the attachment circuit versus utilization of interim
solutions based around tunneling) and the general lack of vendor
support on legacy systems for dial.

In order to bridge this gap, folks primarily involved in the
operational facets of deployment (us) and folks involved in the
standardization of operational protocols (derived from consensus and
running code, developers and researchers) will continue to be the
driving factors to bringing an IPv6 internet to the regular folks out
there. RIRs will play a role in requiring more stringent verification,
but can do little else than deny or revoke blocks to which they cannot
mandate the cessation of utility.

As Paul said, there are more organizations moving to a pure IPv6
infrastructure, but they still are the minority of deployments and
will continue to be for the near to long term. I cannot imagine my
current enterprise making major overhauls in their developed systems
and acquired platforms to meet a need that simply does not exist
*now*. Many more enterprises are like mine. As network professionals,
we *should* be espousing the benefits and necessity of IPv6, but we
will (in most places) continue to be rejected until a bona fide
business need can be presented. Since such a minority are utilizing an
IPv6-only solution at the attachment circuit, there is little
motivation or (in business terms) justifiable need to provide these
services.

There are more concerns in v6 like the lack of NAT which breaks
PCI-DSS compliance, etc but that could be an essay on its own.

My 50 cents (inflation is high). YMMV
