Latin America Exhausts IPv4 Addresses 197
An anonymous reader writes "LACNIC, the regional Internet registry for Latin America and the Caribbean, considers its IPv4 address pool exhausted, because it is down to less than a quarter of an /8, roughly 4 million IPv4 addresses which are reserved for facilitating transitioning mechanisms. Half of those addresses will be assigned on a first come, first served basis, but no more than 1024 addresses per organization every 6 six months. Allocations from the last 2 million addresses will be a maximum of 1024 addresses total per organization. To maintain connectivity, it is now indispensable to make the switch to IPv6. LACNIC's CEO expressed his concern that many operators and companies still haven't taken the steps needed to duly address this circumstance. The RIRs for Asia-Pacific, Europe and North America have all imposed similar limitations on IPv4 assignments when they also crossed their local exhaustion thresholds. As of now, only AfriNIC is not in address exhaustion mode."

It's still quadrupling the information (from 32 bits to 128 bits), though most IPv6 addresses can be shortened.
But to be honest, this is what DNS is for. If you find yourself regularly having to memorize or manually type dotted quad IPv4 as a user, you're doing something wrong; and if you're a sysadmin, you're routinely memorizing (or writing down) other things that are more complex than that.
Mnemonics could also help, like assigning words to bytes [wikipedia.org].

which is a lot longer than an IPV4 Address such as:
123.123.123.123
And IPV6 address has 4 times as many digits as an IPV6 address, if you write it in the same base. That's way more than just adding and "area code"

An actual example of an IPV6 address is as follows:

That is not an actual example of an IPv6 address. Lets try with some real examples instead:
google.com has IPv6 address 2a00:1450:4005:801::1007
gmail.com has IPv6 address 2a00:1450:400f:803::1016
facebook.com has IPv6 address 2a03:2880:2110:df07:face:b00c::1
arin.net has IPv6 address 2001:500:4:13::124
arin.net has IPv6 address 2001:500:4:13::125
ripe.net has IPv6 address 2001:67c:2e8:22::c100:68b
gigabit.dk has IPv6 address 2a00:7660:0:50::2

Kinda how IPv6 works; except there's only one two-octet area code (2002::, or 32.2. in dotted decimal) for the old IPv4 addresses, and all the other addresses work differently.
(Of course, if the recipient only understands IPv4, and the sender only has an IPv6 address, then the packets can only be sent one direction. I'm not sure if or how an IPv6 host and an IPv4 host can establish a TCP handshake, starting from either end.)
I too wonder about that too. (Score:2)
Like forcing IPv4 to stay in country only. If you want to go to a server in another country, you have to get there via IPv6.
Or give each country a IPv4 address range, but certain addresses are reserved for international servers. Multiple IPv4 networks that overlap on addresses that are outside the country.

Emphasis added. Until the freebie routers start handing out IPv6 blocks by default and routing IPv6 traffic cleanly, this will never work. Why on earth would you need to actually do any work by hand?

I recently upgraded my old DSL to Uverse (with one of the newer Motorola modems, not the 2wire modems that I hear were total crap in comparison), and they have 6rd [wikipedia.org] allocations set up for their IPv4 space, using a 24-bit 6rd block. So not only can I access the v6 internet, my 6rd address block is static based on my static IPv4 address block. (At least if and until they decide to more their customer addresses into a "real" IPv6 allocation.) As I understand it, the modem itself does the 6to4 encapsulation to A

Do like I did, get a free 4to6 tunnel from tunnelbroker.com, a public service from Hurricane Electric (he.com).

And even if your ISP offers v6 support, they often "forget" to tell their support. If yours offers v6, if you have some spare time and want some entertainment on support's expense, call them and ask them for aid in setting up v6.

One of the problems with IPv4 address exhaustion is that routing tables become very complex. Having everyone try to glom a dozen random /24s together to make their local networks will not help.
Also, this is an exponential growth situation, so stopgap measures won't buy much time anyway.

Why has people not generally adopted V6 years ago ?
Probably because the hardware in (almost) every routing device needs to be updated to support it. Even if you went with a simple expansion of IPv4 it wouldn't be simple because a router that's looking for a 4 byte address isn't going to know what to do with an 8 byte address. Might as well go with a 16 byte address while we're updating everything.
