If I see IPv6 implemented worldwide in my lifetime, I'll be really surprised.

It is.

There are even ways for reaching IPv4 hosts from IPv6.

It is.

At the risk of extending a longstanding argument, the article reads:
IPv4 mapped addresses are normally used by the IP stack to represent IPv4 addresses to IPv6 applications. It allows the transparent use of transport layer protocols (TCP or UDP) over IPv4 through the IPv6 networking API.
In other words, it is not a mechanism by which IPv4 software a

How we do prove that we are truly running out of IPv4 address?

This is something that every needs to see. This should go a long way towards fighting the 'anti-IPv6 because the addresses are hard to remember' crowd of cry babies. Yes, Virgina we are running out of IPv4 allocatable addresses.
bycortana ( 588495 ) writes:
In other words, it is not a mechanism by which IPv4 software and hosts can use IPv6. It is instead a mechanism by which IPv6 software on dual-stack hosts can use IPv4. I can't just plop down a special router and poof my IPv4-only hosts can interoperate with your IPv6-only hosts at least until we run out of IPv4 addresses.
It sounds like you want 6to4 [faqs.org]?
bySpazmania ( 174582 ) writes:
I won't diss 6to4. Its a good idea that could have been great but for network operator resistance to accepting the IPv6 routes as native annoucements. (The RFC forbids it due their objections.)
But no, what I want is what I said I want: to configure my IPv6 hosts with my old IPv4 addresses and have them interact with everybody else doing the same as well as the old IPv4-only hosts who can't, right up until the moment where the IPv4 addresses run out and we have to start allocating IPv6 addresses which aren't

Ok... ok... so, you're a landlord, and your tenants have trucks inside them, and these trucks have IP addresses?
But I must be missing something?
Eh? Oh no, I'm sure it's me...

I think the mod needs a bran muffin. :-)
byAGMW ( 594303 ) writes:
Flamebait? No, I was genuinly curious, but someone has answered me later on ... it is because of the different datagram [wikipedia.org] formats. This makes it unpossible for the two networks to interoperate.
Sorry if my question offended you!
bymengel ( 13619 ) writes:
The datagram formats are different between IPV4 and V6, but the parts of them that people
actually use are readily translatable. So you can setup border translators between
IPV4 islands and and IPV6 network or vice-versa.
byarun_s ( 877518 ) writes:
This is actually already possible. There are at least two types of v4-compatible v6 addresses (the first one's deprecated, I think):
::127.0.0.1
2002::127.0.0.1
Anytime you move from a v4 to a v6 network, your gateway automatically prepends the 2002:: prefix to make your IP a v6 address. The problem here is that you have to have a public IPv4 address for this to work. If you're inside a NAT'ted network, your private address wouldn't be translatable to a corresponding v6 equivalent.
p.s. a link [twibble.org].
byjez9999 ( 618189 ) writes:
Where'd you get 2002:: from? I thought IPv4-mapped addresses were ::ffff::IPv4 address.
bySpazmania ( 174582 ) writes:
No, 2002:: is for 6to4. You map the IPv4 address in right after the 2002 and the machine at that IPv4 address serves as the gateway to a /48 of IPv6 addresses. For example, if your 6to4 gateway's IPv4 address is a.b.c.d then its IPv6 address is 2002:aabb:ccdd::1 and it supplies IPv6 connectivity for 2002:aabb:ccdd::/48.
6to4 is a good idea that could be great but isn't because it depends on a small network of volunteers to run encapsulators and decapsulators. The volunteers would be overrun if any meaningful

Yes, the whole IPv4 address space exists in IPv6 see IPv4_mapped_address [wikipedia.org].

Dude, we've been over this. It's not a truck. It's a series of tubes.
