[Business] IPv6 Availability

Well, considering there has been zero communication for business customers I thought I would try and ask again about Native IPv6 for business customers.

The last time this was asked, yes this is somewhat of a rant, we were told that it was do to making sure that everything was "perfect" before rolling out to business customers to ensure there were no issues. Well, given the latest speed upgrade and ongoing fiasco for business customers, I no longer see the stance of making things "perfect" before a roll out, or at least beta testing for those of us wanting it and understanding there could be hiccups, as being a credible reason.

So, what is the status of IPv6 for business customers at this point?

I am curious about this as well, in light of the fact that I now have the Netgear device, which although not listed as supporting IPv6 on the supported modems list, should support native IPV6.

*edit* and honestly, I'm very unhappy with this speed upgrade thing, too. I know ComcastDJ See Profile and jlivingood See Profile were helping drive this, but that was when it appeared to be a modem config issue (which we now know it's not). Don't mean to derail your thread with this, but wanted to point out I am also not very happy with how that has been handled.

Don't worry about derailing, I am in the same boat as you on that.

I was reading the Comcast IPv6 site: »www.comcast6.net/

And I do not understand this because there's no clear information on HOW to use IPv6 with Comcast.

1) How do you know if your area has IPv6?
2) If your area does have it, and you have the correct modem and an IPv6 device, how do you use it? Just plug it in?

You can try configuring for it and see if it works. Or you can look around the forum some. One of the Comcast folks who posts here can take your cable modem MAC address and check to see if IPv6 has been deployed on your local equipment. See: »Re: [IPv6] My router doesn't work over IPv6

said by joako:

2) If your area does have it, and you have the correct modem and an IPv6 device, how do you use it? Just plug it in?

What I did here for native IPv6 on my m0n0wall router is this:

On the router WAN interface set IPV6 mode to DHCP.

On the router LAN interface set IPv6 mode to DHCP-PD,
Set IPv6 Prefix Delegation to 0/64,
Enable IPv6 Router Advertisements with Managed Flag.

Your computer(s) must have their IPv6 stack enabled and set to receive router advertisements. How this is done varies with OS.

The nomenclature will vary from router to router, but should be similar enough to be able to get it right.

If native IPv6 is not deployed in your area yet, you can still use IPv6 with a Tunnel Broker such as Hurricane Electric or maybe an IPv6-over-IPv4 tunnel using a Comcast gateway if they are still enabled in your area.

A Hurricane Electric tunneled IPv6 setup has the benefit of static IPv6 address assignments, but it is tied to your IPv4 address which may be dynamic. If it changes you will have to update that endpoint at Hurricane. There are automated tools that can do this for you, they too vary with OS.

Good luck.

Is a router required? Wouldn't a Windows 7 PC with default settings work with IPv6?

Well, I did try tcpdump'ing for ipv6 traffic, but did not see an RA packets. But that doesn't surprise me since the Netgear doesn't have any IPv6 info in it's network information page.

The status is that if you are a business class customer with a dynamic IP account, and you are using a standard cable modem, or an SMCD3G-CCR in bridge mode (I don't know about the new Netgear gateway), and if you are connected to an Arris CMTS, you should get native IPv4/IPv6 connectivity.

What would you like to see to help out with this?

said by joako:

1) How do you know if your area has IPv6?

Take a device what supports DHCPv6 and plug it into the cable modem to see if you get an IPv6 address. IE Windows Vista, Windows 7, or the latest version of Mac OS.

Or ping me via PM with your cable modem HFC\RF MAC address and I will check on this for you.

If you use IE Windows Vista, Windows 7, or the latest version of Mac OS directly behind the cable modem you would be good to go.

If you have a router you will need to check for DHCPv6-PD support and enable it. Do you have a router?

PM NetDog See Profile with your info (modem MAC, modem make/model, service address). We'll add you to the list for January, when we expand from an employee-only trial for business customers. In some cases we may need to send you a new device but we'll handle all that.

Folks we are going to create a shared document that you will be able to enter your own information into so we can skip the data entry aspect of this on our end. Interested parties will enter their own information which Comcast can only see. This will make everyones life a bit simpler.

Folks, if you want to sign up for the IPv6 trial that is fine. But would you please quite replying to me and use the correct reply button that is included in each post and reply to the fellow Comcast poster.

That is the price you pay for starting a thread on this site. Many (if not most) posters on this site don't know (or care about) the difference between replying to a specific post and replying to the thread (which by default is addressed to the thread's originator). I blame this site's default flat/linear thread display theme (as opposed to a default nested scheme that is common on many other message boards/forums) for much of that confusion.

You can disable the reply email notification if you are being bombarded with email notifications for replies to this thread (I keep that option turned off precisely for that reason).

If you have residential than your IPV6 should be turned on assuming you are behind the "right" CMTS.
This trial is probably only geared towards business customers that want multiple static IPV6 addresses.

It has been implied to me that even though I have a business class account, and my SB6121 has a business class config file (d11_m_sb6121_bciwidebandstarter_c05.cm), and I have fully functional native IPv4/IPv6 connectivity, that I don't really have business class IPv6 service.

It will be interesting to see exactly what jlivingood See Profile et al are talking about if/when the proposed shared document (which hopefully might also contain some documentation) is published.

There's probably 4 categories of customers:

Residential
Business w/ Customer Owned (i.e. DHCP)
Business w/ SMC or Netgear (i.e. Static)
Business w/ non-HFC installation

The first two probably already have access to IPv6 if their area has been enabled, though which ones this would apply to, I do not know for sure, as I am behind the "wrong" CMTS...

4. Business w/ non-HFC installation

From what I understand, #1 and #2 cases already have dynamic IPV6, and probably won't get static. #4 probably also already has static I believe, especially since they get straight up metro ethernet now according to the 305 install thread.

So I think this only applies to group #3.

The next question is, does Comcast expect to have to replace everyone's SMCD3G modem to hand out static IPV6.
Since we don't have an answer on this yet, I am going to predict the answer will be yes. SMC has had plenty of time to upgrade the firmware...

There is also another class of Business Class customers:

Business w/ SMC or Netgear (DHCP)

And a subclass of Busness Class customers using the SMC gateways who will almost definitely need a new "modem" in order to get IPv6:

Business w/ SMC8014 gateway (DOCSIS 2)

Good point on the SMC 8014 (I still have a mental block regarding that device). I do think however the SMC / Netgear customers whether they are DHCP or static are probably in the same category.

The trial coming up is geared to users with a CCR modem. If you have business class service with a modem that has been approved for IPv6 look here under the IPv6 tab: »mydeviceinfo.comcast.net/?s=i&so···1&sc=619 then you should be good to go (if your on an enabled CMTS).

If you have business class service with a CCR modem it is not setup yet. I am also not sure about SMCD3G-CCR in bridge mode, I have not tested that so I cant say yes\no to it.
