Not able to get IPv6 address on Hitron

I signed up with Rogers in late december last year. So far I was able to get IPv6 address on my home network from Hitron modem. Since last few days I am noticing that my home network was not able to get IPV6 address. I dig more depeer and found that hitron CGN3ROG modem (firmware version 4.2.4.7) itself was not able to get IPv6 address from CMTS on its wan interface. Thus it cannot get deligated prefix. I used to get 2607:fea8:4220:3f9::/64 for my home network. I also tried rebooting modem multiple times in multiple ways.

 

I chatted online with support on this but got very disappointing reply. They said I cannot get both IPv4 and IPv6 address anymore. I asked them to look into CMTS if they turned off IPv6 there but they refused to look more or escalate to someone who can help. 

 

anyways All I wanted to confirm if there is some changes in my area or my modem firmware got changed.

Re: Not able to get IPv6 address on Hitron

Probably the last thing to try is a factory reset.  After the reset, log into the modem and check for two IP addresses in the WAN IP address field which is located in the Upper right hand corner of the STATUS page.  That STATUS page is displayed when you log into the modem.  If the modem does not have an IPV6 address at that point, I would conclude that the CMTS is not assigning one to the modem.  You would need to speak with a Level II tech.  The Level I tech won't be able to help you.  So, first step is to get thru to the Level II tech.  Just ask the Level I tech if he or she can either reboot the CMTS or fix the configuration.  If not, then simply pass you on to a Level II tech who can do something about the issue.  Its possible that the Level II tech will have to pass this on to the Network Engineering staff.  See what happens when you are chatting with the tech.

I do not think level1 has ability to reboot CMTS since it will affect customers in whole area. I will try to factory reset and see how that goes.

No, we cannot reboot a CMTS, but we do have access to tools that can display the public IPV4 and IPV6 address.

worked after factory reset, wonder what caused this issue.

Re: Not able to get IPv6 address on Hitron

Don't know.  Possibly a configuration change at the CMTS which for some reason resulted in the modems not receiving an IPV6 address.  This worked, so, its something to remember if you have the same issue down the road.

@borford are you a Level I or Level II tech or Network Engineer by any chance?  Just curious.

Re: Not able to get IPv6 address on Hitron

I have had my cable modem in bridge mode for a long time. Today with not being able to connect to some ipv6 sites I tried several ipv6 dhcp requests and received no reply. I took the modem out of bridge mode and found the modem had an ipv6 address, but no options to assign an ipv6 address to the lan. How does rogers do ipv6? Is it still done via a tunnel to somewhere?

Hardware version 1A

Software version: 4.5.8.27

Cable modem: CGN3ACSMR

Re: Not able to get IPv6 address on Hitron

@drjohnst, Rogers shut down IPV6 tunneling as of 18 May 2017.  Native IPV6 has been in use for some time before tunneling was shut down.  Here are various IPV6 settings which will hopefully provide the info required for your router:

Modify the router settings as required and then kick the modem back into Bridge mode and reboot the router so that the CMTS assigns an IPV6 address to the router.  Please let us know if you've been successful or not. 

 

Here's the 6rd and a 6to4  shutdown announcement from last year:

Fwiw, here's a thread from DNSReports for IPV6:

Re: Not able to get IPv6 address on Hitron

My router shows an ipv6 address but that's not what is being broadcast when I browse an ipv6 site. When I look up my ipv6 address on the internet it's the address the router has assigned my PC. If I connect with my laptop, it'll be a different ipv6 address than my PC. 

 

@Datalink Is this the tunneling you're speaking of? It'd be nice if the ipv6 address from the router was as stable as the ipv4 address, meaning it would stay the same for a long block of time.

 

Is this what commonly happens? I have some servers that I routinely connect to and like to lock it down to an ip address. I can live with the fact that while the ipv4 address is not static, it doesn't change very often. However, the ipv6 address assigned to my pc or laptop by the router changes frequently.
