Comcast IPv6 Shift Kicks Into High Gear
Activates First Group Of IPv6 'Native Dual Stack' Users
by Karl Bode Monday 31-Jan-2011 tags: business · bandwidth · cable · Comcast
Comcast, already further ahead of the curve on the IPV6 transition than most carriers, dropped us a line to note that the company today successfully activated the first group of cable modem customers using IPv6 in a dual stack configuration. In other words, those customers now have both IPv4 and IPv6 addresses and can access IPv4 and IPv6 services natively. "On January 11th, 2011, our first 25 IPv6-enabled users came online in the Littleton, Colorado area," says Comcast in a blog entry. "Since then, we have expanded the number of users in Colorado and we will soon expand to additional market areas in other parts of the country." As usual, Comcast networking folks are available in our forums for those interested in asking additional questions about the transition. Comcast says the pace of deployment will be determined by the success of this portion of the trial, but additional users should be incorporated into the tests shortly.

IPv6 Routers

Cool... but my mind is just floored by the thought of all those cheap consumer routers that are currently out there in the wild that will also need to be replaced.

On that note, anybody know of some good routers that support IPv6 right now?

Actually no, I believe the last 2 or 3 revisions all support IPv6. I have the newest dual-band version and I know it does.

You can't add IPv6 support with a firmware update on those "cheap consumer routers"? Or is it that the manufacturers don't even support them anymore?

I give Comcast a lot of credit for pushing forward on Ipv6. It's nothing short of inevitable.

Not a HUGE fan of Comcast, but I give them credit on this one. A lot of users are going to see disruptions due to the need for Ipv6, so to bring it to the forefront is a good thing for everyone....

Any of the Linux-based routers (Linksys, Buffalo, Asus, some Netgear units, etc.) with third-party firmwares tend to support this, although TomatoUSB is behind in this regard -- you apparently have to try a trunk build which has 100% confirmed (serious) bugs in it per the person who built it.

AFAIK, there aren't any consumer routers that do IPv6 out-of-the-box.

There are a number of D-Link routers that do. Billion has 2 models that do now and new firmware will be issued soon for a number of existing models. Netgear has beta firmware for a few models too. Strangely enough for Cisco owning the Linksys brand they're epic fail for v6 support.

Interesting, didn't know about D-Link having IPv6 support, and have never heard of Billion. I imagine that most users are not going to run beta firmwares, so that mostly rules out Netgear (as of this writing). I imagine it's going to fall on the responsibility of ISPs to tell their customers "if you have router X, you need firmware version Y to get IPv6", and I imagine a lot of residential router vendors aren't going to provide IPv6 stacks on lots of routers for multitudes of reasons (limited flash space, deprecated hardware, too many subrevisions of hardware to deal with, you name it). I'm certain the industry will use this opportunity to try and force customers to replace their hardware.

As for Cisco/Linksys, it's important to remember that Linksys is a subsidiary of Cisco, which means they effectively operate on their own. Linksys has historically subbed out all of their firmware work to a company in Taiwan called CyberTan, and this hasn't changed despite the buyout. TL;DR version: Don't expect Cisco enterprise quality from Linksys products.

On the other hand, I think the DD-WRT 3rd party firmware does offer IPv6 capability, but lots of people tend to stick with the Tomato series simply for its UI and fairly slim-lined operation (DD-WRT is a beast).

I understand that, but it's still egg on Cisco's face. I also don't expect the same quality. But Cisco has been able to deal with v6 support for the majority of their other products with the big exception being the Cisco (Linksys) CPE gear which is the biggest issue holding up further mass scale roll out of v6.

It looks like the internet has run out of IPv4 addresses

http://www.iana.org/assignments/ipv4-address-space/ipv4-address-space.xml

Sort on status and look for UNALLOCATED.

The 5 remaining blocks of IP addresses should automatically be given out today, or ASAP.

A co-worker of mine who also is part of ARIN tells me that the remaining five /8 networks will be delegated later this week. I still want to know what in the hell APNIC needs all of this IP space for.

Sorry, doesn't fly. Every device in the world does not need a public IPv4 address to function; NAT, despite being an atrocity, takes care of that. Hint: APNIC has over 37% of the entire IPv4 space. Ask yourself if they really need that much.

No NAT does not take care of everything. There is more to the Internet than consumer Internet connections.

Let me put it into numbers for you. APNIC has 46 /8 networks allocated to them as of today. Not taking into consideration subnetting requirements (e.g. broadcast and network addresses), that's 771,751,936 IP addresses (16777216 * 46) allocated to just APNIC.

Seven hundred and seventy one MILLION IP addresses for effectively one region. So again: what the hell is APNIC doing with all of this address space?

Not every website needs its own unique IP address. Virtual hosts have been in use for years and every modern day browser supports virtual hosts on the server side. You can point several web server names to one IP, it's not rocket science.

There are more legacy allocations of entire /8s to individual US organizations than allocations to APNIC. Counting these legacy allocations together with the ones to ARIN, the US and Canada have close to half of the available space.

A lot of those allocations are to formerly US organizations. I think IBM, HP, Cisco and a number of other formerly U.S. centric corporations hire more people in India or China than the U.S.

How would we persuade a large multi-national corporation to surrender half or more of it's non-replaceable and free IP addresses?

You don't, why try to delay what everyone has known will happen for over a decade? As the saying goes, "Poor planning on your part does not constitute an emergency on my part."

IANA long ago determined that asking legacy netblock owners to return space wouldn't result in any meaningful delay. I believe they did get one or two /8s back anyway. Though we are currently using up about one /8 per month, so that only delayed it by two months.

For any organization that isn't ready or actively working on it, do you really think they will make any progress if they are given more time? No, they'll just put it off for another year and then complain again that they don't have enough time.

@rr.com
What's wrong with APNIC having 46 /8's? The APNIC region is bigger in population that the ARIN region, and ARIN has a whole hell of a lot more /8's than APNIC.

What you should be complaining about is why is AFRINIC getting one of the last 5 /8's when they just got a /8.

Just how fast do we think the Internet in Africa is growing?

Someone tell Karl!

Even when these /8's are allocated from IANA to the registrars, they won't automatically be used up. They'll still be assigned out in pieces according to the registrars' policies.

They are still going to be allocating them for the next couple of years, and it will take a couple of years after that until the companies that received these IP's are using them all.

By then, hopefully panic mode will have kicked in for IPv6 and it will be more widely used on the content side.

Which Router Setting Should I Use?

Attached is a screen shot of the router setting options I have for a DIR-655. Presently set for "Local Link", which (I believe) allows the "Home Group" networking feature to work.

The option you should use depends on who your ISP is and what they told you to use to obtain an IPv6 address.

Link-Local should always be active in IPv6, regardless of what you have set. It is part of the IPv6 standard, the IPv6 link-local addresses are auto generated by the OS based, and will always be the same.

Re: they should

An easy way is to just build the router yourself. Get an unused computer, put 3 nics in it and install pfsense. 1 will be wan, 1 lan, and for the third use a wireless pci card. This setup will setup ipv6 out of the box and you will have an ultra secure firewall for your network as well.
