Re: [IPv6] Deployment of IPv6 Begins

said by Mike Wolf:

Plus I got the same E4200 router, Just be sure to update the firmware to 1.0.03 since it includes native IPv6 support

I just updated my brand new E3200 to the newest release (1.0.02 (build 9)) and it also includes IPV6 native support. The release notes state: "This build is certified with the IPv6 Ready Logo Phase-2 (Gold)." Hopefully that's a good thing.

hey greybeard long time no see!! man its good to see your posts again. I've been so busy on the tv side of things I completely forgot about this side. Anyway the update for my E4200 said the same thing about phase 2 gold but it still doesn't have 6to4 configuration support as an option.

I'd consider the lack of 6to4 on the E4200 a good thing. It's being deprecated and has caused some serious brokenness on the IPv6 internet.

While you wait for native v6, you're much better off getting a static tunnel from HE or SixXs (AYIYA works from behind NAT), or even using Teredo.

Re: [IPv6] Deployment of IPv6 Begins

but I for some reasn can't figure out how to make the HE and SixXs stuff work lol. I'm used to the 6RD settings where I can enter them into the router configuration page.

Umm? 6to4 comes higher up in the ipv6 prioritization than Teredo. Most OS's will prefer it to Teredo (and many OS's don't even support Teredo without additional software, namely Miredo). 6to4 works fine as long as the tunneling is working which is true of Teredo or a static tunnel. As to working behind NAT, that shouldn't matter if he's willing to run some ipv6 software on the router. My router does the 6to4 work and it advertises ipv6 addresses to my machines on the LAN. They don't need to deal with NAT'ed ipv6 because the ipv6 isn't behind any NAT. If my router didn't support ipv6 then yes I'd agree that Teredo or static tunnels might be a better option. And I'd go with static tunnels being preferable to 6to4 but not to Teredo.

And to my knowledge Comcast doesn't run a Teredo exchange while they do run 6to4 exchanges. So performance should be better with 6to4 over Teredo.

I'm pretty new to IPv6, but I guess my main question is how dual-stack will play out in my household on a few devices that, from what I've been reading up on, aren't exactly IPv6-ready:

- Linksys WRT54G v2. I can install OpenWRT, and if this fails or bricks, I'll go buy an E4200.

- Windows XP Professional SP3.

- Tivo Series2 with USB-Ethernet dongle. Uses the Internet, but I also access the TiVo from the LAN to download TV shows to my computer.

- Nintendo Wii with USB-Ethernet dongle. Uses the Internet.

- EpsonNet parallel print server. Only used within the LAN.

I'm using DD-WRT on my Linksys router, and it supports IPv6 (I've been using 6to4 on Comcast for the past few months). Not sure how OpenWRT IPv6 support is.

Should work fine - Google if you can't figure out how to get it working.

Don't worry about these devices. They'll be able to cruise along just fine on the existing IPv4 network. By the time v4 is deprecated (nobody is seriously talking about timetables for this yet - probably decades), this equipment will be museum-eligible.

Dual-stack allows existing IPv4 devices to function just as they always have: they'll ignore the IPv6 packets that they don't understand. To enable IPv6 on your network, the only things you need to worry about are the core networking equipment - probably just the cable modem and router (network switches will work fine - they work at a lower layer than IP).

Technically, the TiVo, Wii, and EpsonNet could have their firmware/software upgraded to support IPv6. TiVo seems to do an excellent job continuing to support old devices, and I could imagine Nintendo being interested in making the Wii work with IPv6.

Epson, OTOH, seems to have abandoned the EpsonNet, however, looking at the printer marketplace, I am fairly confident that our next home printer will have on-board Ethernet--currently looking at the HP LaserJet CP1025nw.

Currently I have a 6over4 tunnel via hurricane electric with a /48 which I then have split into multiple /64's for my vlan's, so will I be able to get a /48 from comcast?

i'm not sure those companies are all that willing to put the effort into IPv6 support, I mean TiVo can't even update their Premiere models regularly with stability patches let alone finish the HD menu and activate the second half of the dual core processor, and Nintendo will probably hold off until their next gen console. PlayStation 3 on the otherhand is a toss up and am hoping they do include IPv6 which has been asked of them by a large majority of their customers for awhile.

Jason,

Thanks for yours and everyone's hard work on this project.. definitely a huge improvement.. However, it is a bit ridiculous that Business customers can't use it.. and like someone else said their sales person is clueless, it's the same with mine. I just renewed my contract for 3 years because I love the speeds, and 24 hr support for business, but why in the world did business customers get left out?

I know the techops manager and headend manager here personally, but it doesn't help anything suggesting to them, because A) they're just doing what is pushed down to them and B) I'm just a lone business customer in a coverage area of 95,000.

Can you shine some light on this at all?

@SolarPup,

Can you support 6to4 tunnel? Comcast has a 6to4 tunnel online for Comcast customers. Here are the directions: »www.comcast6.net/6to4-config.php

In this case it is easier to start with residential first, as the devices are simpler cable modems without a gateway/router/firewall function. This is one of the reasons we did not lead with support for home gateway devices - it is incrementally more complex. So we want to get rolling now, so that means we wanted to focus on the simplest possible operational and support scenario.

Next up is home gateway support. After that I imagine it will be business class support. You can rest assured I see it as a priority. But we need to get SMC to deliver IPv6 support, which we are working on (and Business Class folks are watching this thread).

Jason,

Would you be able to shed some light on a few things? Even if just one of these would be great. I am doing a lot of IPv6 education in the local area and I fully expect a whole lot of questions surrounding Comcast's IPv6 deployment (and many more people to show up to my talks).

#1. What's the plan as far as prefixes go, ultimately? Will residential customers be able to pick up larger than a /64 for their own purposes? A /60? /56? /48?

#2. Are there any plans on charging per individual devices found with globally routable IPv6 addresses on a customer's network?

#2 sounds far-fetched to me but it was a question I've already been asked by a few people and would love an official answer to.

Per »blog.comcast.com/2011/11/ipv6-de···ogy.html we will support shorter prefixes eventually in 2012. But initially it will be just a /64. Exact timing in 2012 is TBD. We'll announce more details on this when we begin deployments supporting home gateway devices.

Not at this time. IMO this would discourage demand for IPv6 and this in turn means less content on IPv6 (that's the opposite of what we want - which is pervasive IPv6).

Got two questions for you.
1. Are Comcast's v6 DNS servers whitelisted on Google?
2. Has there been any discussion about v6 on Xfinity WiFi ( »www.comcast.com/wifi/ )?

1 - No, not at this time.

2 - Yes, and this is planned for 2012 (hopefully).

SMC implies that their SMCD3G-BIZ model is already IPv6 capable.

Separating reality from brochureware is our speciality on these device tests. That device does not really and truly support IPv6 yet in our view. We are hopeful that it soon will.

I think they are probably referring to cable modem management ipv6 support. I don't recall seeing any configurable ipv6 options in the SMCD3G for static ips, dns servers etc.

Which brings an interesting question to mind, will RIP-NG be used or some other design for assigning static IPs (I hope not static routes!)

Thanks for the info!

Good stuff. Can't wait to get off of this tunnel.

Here's another one for you, less Comcastic, more Technical.

Have you guys seen any tangible improvements in throughput with IPv6 versus IPv4? How has the lack of checksums on v4, lack of PMTU on routers, and the reduction in NAT improved network performance as a whole?

Would be awesome to see a paper or talk given on that!

I like the sound of that, I will talk to the RMv6TF about adding that to the 2012 North American IPv6 Summit..
