There is no plan B. Despite the long list of the issues with IPv6 and its deployment, there are no alternatives. It took us the better part of two decades to get this far with IPv6—, and there's no way we can come up with, implement, and deploy an alternative before the lack of IPv4 addresses becomes a serious problem.

There's potential solutions for TSI, but none of them I'm sure are palatable  .
Free up their DSL IP base. How?...Remove the availability of reserved IPs, or start NAT behind the DSL base, say for their lite user base. These users more than likely are not power users to begin with, and depending on how many of them there are (not having numbers makes it impossible to figure out), may free up enough space to reallocate to cable.
Because you're not going to be able to set up NAT on the cable side, since they're just giving IPs to Rogers.
It may be something worth investigating. |

Actually the issue has to do with ARIN policy and not the scarcity of IPv4 addresses. Although that will become an issue within a years time when the last of the usable blocks are allocated and there is nothing for ARIN to hand out.
At some point Rogers will have to change their policies because its only a matter of time before RFC1918 address space will have to be given to customers. |

1 edit | And I note that the IP space information from the web site is from January 2010. It's in fact much worst now.
We in fact only have about 5% of the total usable IP space left to allocate and it's predicted that we will run out within about 6 to 8 months. |

The IPv4 to IPv6 transition I think will be a complete mess, definitely will not be smooth at all.
So much software and hardware devices still do not support IPv6 addressing, and some never will, which will create problems with IPv4 clients being unable to connect to IPv6 hosts and vice-versa. To alleviate issues ISPs will start putting residential customers behind NATs for IPv4.
It's going to be ugly, no doubt about it.
Ideally the transition should have occurred long before the impending depletion of IPv4 address space, to allow enough time to gradually phase out IPv4 and bring in IPv6.
We waited too long, and now we're going to pay the price. Unfortunately it's human nature to wait until disaster occurs before taking action, rather than planning ahead. All those ISPs and corporations out there probably thought they'd save money by holding off on the upgrades, but in the end they'll only end up spending more.
I'm surprised that the larger ISPs haven't started rolling out IPv6. Then again not really. They probably figure residential subscribers shouldn't be hosting servers and thus will be just fine behind NAT. |

Anjou, QC | Maybe Arin should have thought once twice before handing out /8's to Compaq, MS, and company. I'm pretty darn sure Compaq doesn't need all those IP's.

Any possibility that TSI can be using IPV6 in DSL land so that existing pools can be moved over to Cable Internet? Afterall, ISP has a bit more say on how IP addresses are handled on DSL.
FYI: Comcast has started IPV6 trials. Until Rogers moves over to IPV6, it might be difficult to use that over there. |

Even if they could recover those /8's from them, it would only delay the inevitable. With the population base of the developing nations all coming online, they'll eat up those addresses in no time. |

I wasn't saying it would fix any problems, however I think any additional time to prepare for v6 is good at this point.

I think they are testing it now with MLPP and a limited number of volunteers. Haven't heard anything more about it for a long time though..I wonder how it's been working out.

The problem is as always, dragging of the heels like the article references. Should we still have networks that are created to be backwards compatible with 10mbps?
Should the wireless people who are at 802.11 still be supported with their 2mbps super speed?
Should we still have ISA slots on our motherboards just incase people want to slap a card in there?
At some point the legacy hardware has to be let go. The problem is, 20-25 years ago I'm sure they didn't think we'd STILL be on ipv4.
Problem is there is SO MUCH Legacy hardware out there! And some of it is relatively new and some of it is very proprietary and specific (read expensive) hardware.
And its those companies that will be up in arms. At my previous employer we installed basically a fancy vinyl printing device for signs and other functions...oh boy it had IP capability!...you think it would have DHCP capability?....Hell No. A $60,000 piece of equipment that was manufactured in 2009 did not have this capability.
My employer would never flip to ipv6. The amount of equipment that they have that would break would be insurmountable....oh wait they'll be FORCED to upgrade and spend the hundreds of thousands of dollars, and will inject money into the economy...
On second thought lets get this ipv6 running now! Lets exhaust the ipv4 space IMMEDIATELY. For the record they have a /16 assigned back in 1995. I can tell you based on info that they're not even CLOSE to exhausting that space, in fact the opposite has occured, they have more private addressing occuring now then they did back then and have basically have tons of space that's idle.
Maybe ARIN should go back and reallocate based on current usage. I'm sure there are lot of those types of companies out there that are wasting space that could be better used. You know like when the phone company recycles numbers faster before they add an area code. And they can do it now with sophisticated routing tables and whatnot.
I wonder if TSI's IPV6 trials are still on hold or not...also does anyone know if Tomato supports ipv6? I'd be willing to flip...of course there'd have to be some sort of incentive . |

Nope. Not the main stream ones except
- TomatoUSB (Teddy Bear)
- Tomato RAF (Victek Mod)

But I'm saying, at some point, they have to just let go...It may cause some headaches, but...it has to be done.
Eventually I've heard we'll run out of area codes and then they'll introduce a 4th digit....will chaos ensue then as well?....Who is to know. |
