Why the Journey To IPv6 Is Still the Road Less Traveled
alphadogg writes The writing's on the wall about the short supply of IPv4 addresses, and IPv6 has been around since 1999. Then why does the new protocol still make up just a fraction of the Internet? Though IPv6 is finished technology that works, rolling it out may be either a simple process or a complicated and risky one, depending on what role you play on the Internet. And the rewards for doing so aren't always obvious. For one thing, making your site or service available via IPv6 only helps the relatively small number of users who are already set up with the protocol, creating a nagging chicken-and-egg problem.
My border router is more than IPv6 ready. It's already passing out IPv6 addresses internally to the few devices which are capable of them. Not that it matters to me though, my ISP doesn't support IPv6 so what's the point? Yea, I can touch my router from my laptop over IPv6, but what does that get me?
Who is my ISP? Why Verizon FIOS of course. Until they decide to support IPv6 and give out addresses to people like me who are ready to use it, there won't be any mass adoption of IPv6 by their customers.
Are their any ISP's out there which support residential IPv6?
There is no benefit to using IPv6 for most people. IPv4 works fine and there are enough workarounds to keep IPv4 relevant for a long time. IPv6, while it gives more address space, does not in itself really carry any benefits for either service providers or end users. That greatly reduces the motivation to switch.
ISPs are not helping. Where I live the local ISP charges extra for IPv6, it's something that needs to be expressedly added onto the account Who is going to want to pay extra to provide/access a service most people aren't using?
Filtering out nmap to places you don't want it to go is EXACTLY what a firewall is for.
And your IPX comparison is also flawed. You don't need to use your MAC address, that is just one way of generating an IPv6 address. And being able to address a packet to any node on the internet directly is exactly how the internet was suposed to work. (Note that a firewall may still prevent such packet from ariving unwanted).

Perhaps you missed world IPv6 day when they both jumped at the same time to enable their front pages? There are a lot of things that don't work right in an IPv6 only world, such as Skype but the list of things that doesn't work is getting shorter. If you take a look at the statistics it's quite encouraging to see a steady growth curve.

Anycast tells you what services are on what IP. There are other service discovery protocols, but anycast was designed specifically for IPv6 bootstrapping. It's very simple. Multicast out a request for who runs a service, the machine with the service unicasts back that it does.
Dynamic DNS lets you tell the DNS server who lives at what IP.
IPv6 used to have other features - being able to move from one network to another without dropping a connection (and sometimes without dropping a packet), for example. Extended headers were actually used to add features to the protocol on-the-fly. Packet fragmentation was eliminated by having per-connection MTUs. All routing was hierarchical, requiring routers to examine at most three bytes. Encryption was mandated, ad-hoc unless otherwise specified. Between the ISPs, the NAT-is-all-you-need lobbyists and the NSA, most of the neat stuff got ripped out.
IPv6 still does far, far more than just add addresses and simplify routing (reducing latency and reducing the memory requirements of routers), but it has been watered down repeatedly by people with an active interest in everyone else being able to do less than them.
I say roll back the protocol definition to where the neat stuff existed and let the security agencies stew.

IPv6 would help both enormously. Lower latency on routing means faster responses.
IP Mobility means users can move between ISPs without posts breaking, losing responses to queries, losing hangout or other chat service connections, or having to continually re-authenticate.
Autoconfiguration means both can add servers just by switching the new machines on.
Because IPv4 has no native security, it's vulnerable to a much wider range of attacks and there's nothing the vendors can do about them.

IPSec is perfectly usable.
Telebit demonstrated transparent routing (ie: total invisibility of internal networks without loss of connectivity) in 1996.
IPv6 has a vastly simpler header, which means a vastly simpler stack. This means fewer defects, greater robustness and easier testing. It also means a much smaller stack, lower latency and fewer corner cases.
IPv6 is secure by design. IPv4 isn't secure and there is nothing you can design to make it so.

Windows has had IPv6 stacks since Windows 95 and Microsoft even started supplying them as of 98.
