IPv6 from broadband ISP?

[MtnMan]

Are any ISPs that provide broadband for the average home moving to IPv6?

My router (Linksys E4200 w/DD-WRT) is IPv6 capable, but my cable modem (Motorola SB6121) says DOCSIS MIMO and IP Mode are IPv4 only. If it has enough resources (RAM/ROM) I guess a firmware update could resolve that.

I have noted that when I connect through 4G on my phone that I get a IPv6 address from Verizon.

From what I understand, we are still using a quite small percentage of available address space available with IPv4. And the subnet space available is equally plenty for most organizations.

But, if this guy is accurate, we can finally say goodbye to IPv4 by 2148.

There are probably large segments of Class A addresses that could be utilized by companies that have a class A but don't need 16M addresses.

But with the number of devices growing at the rate it is, why build the additional infrastructure to support it on a technology strangled by an ever diminishing resource (IP4 addresses).

I have also noted that ISP's are assigning private addresses to subscribers. Friend had Geek Squad setup his router and laptop, and had some issues. While fixing that, I noted that the IP from BellSouth (now AT&T) was a 192.168.x.x address.

This is nothing new. Look at this thread from 2001:

Part of the issue is if you want to buy IPv6 space, you need to buy IPv4 space too. Stupid rule, but it's the rule. So we are still bound by the limitations of IPv4 address space until they get rid of that rule. Most ISPs wont bother rolling out both, they'll just roll out IPv4 if they had to buy that space anyway.

My ISP offers it if you want to use it. Just doesn't seem worth it to switch though. Why introduce potential issues with a new setup for no tangible gains ?

ARIN has been requesting some users to use their address space more efficiently, but there's only so much they can do. Last I heard, the last available IPv4 address (IE: not already reserved or assigned, private addresses are reserved and assigned) was assigned several years ago. (See edit below) That doesn't mean every address is in use, or the addresses are being used efficiently (there are still some institutions that assign a public address from their block to every single host on their network for some absurd reason), but the addresses are assigned, and thus the problem. There are millions of unused IPv4 addresses that are reserved for one purpose or another. The necessity of those reservations is another debate.

The problem with migrating (finally) to IPv6 is... Well, honestly nobody who could wants to. "I already have my IPv4 address(es), why should I do more work and switch to IPv6?"

Edit: ARIN assigned their last IPv4 address on September 24, 2015. I didn't bother to look to see if IANA has any addresses that haven't been assigned to a RIR.
