[IPv6] Not getting IPv6 addressI'm in IL, where I see other's have had success getting an IPv6 address, but I don't :-(
My cable modem is a Motorola SB6121...
Firmware Name: SB612X-1.0.3.3-SCM00-NOSH Boot Version: PSPU-Boot(25CLK) 1.0.12. Hardware Version: 5.0 Serial Number: 35907************* Firmware Build Time: Aug 12 2010 13:58:19
When visiting the modem status page at 192.168.100.1 I see... MDD IP Mode Override (MIMO) = IPv4 Only Modem's IP Mode = IPv4 Only
My router is a Netgear FVS318N with IPv6 turned on, when I visit the WAN status I see...
IP Address | Subnet Mask | Gateway | Status WAN (IPv4) 67.174.**.*** | 255.255.252.0 | 67.174.**.* | UP WAN (IPv6) fe80::e246:9aff:fe1e:6c63/64 | - | fe80::201:5cff:fe24:71c1 | Up
...I take that fe80:: address to mean "Link-local" which is not one that is route-able over the Internet??? Any ideas on what I need to do? |

Those 2 lines mean the modems interface and confige pages are IP4 only for now, the modem can still pass through a IPv6 address. However right now you may only have use of 1 IP address Take the router out the picture. REBOOT/Powercycle everything. If you now have v6 internet you can try adding the router back in and adjusting the settings |

Connect directly to the modem's ethernet port with a Windows 7/Vista machine or a Mac and see if it pulls one that way. If not then you apparently don't have IPv6 enabled. |

I have also a netgear router (although different WNDR3800) and I had to set under Advanced Setup->IPV6->Internet Connection Type: DHCP The default of 'Auto' was not negotiating correctly to talk to Comcast's DHCPV6 servers. |

said by ipv6huh :MDD IP Mode Override (MIMO) = IPv4 Only Modem's IP Mode = IPv4 Only This is what the DOCSIS side of the cable modem is going to do, this doesnt mean anything to the LAN (CPE) Interface. So the bottom line is this doesnt mean anything to the user. This is so the cable modem knows what to do with the DOCSIS side of the modem or the management side of the modem. said by tshirt:Those 2 lines mean the modems interface and confige pages are IP4 only for now, the modem can still pass through a IPv6 address.

The two lines are for the DOCSIS interface only. |

Link-local is only used for the local link, this just means your router is enabled for v6. Do you have DHCPv6 enabled? does it support DHCP-PD? The area your in should have support but with-out your CM-MAC I can't tell you for 100% if the CMTS your on supports IPV6. |

I know that happened to me in S.NJ. I was working on IPV6 since IPV6 World Launch Day and then mid last week it went away and I couldn't get it back, despite doing all the usual methods mentioned above. I never followed up with cust svc, since that would be a waste of time. Cust Svc is NOT ready to help with IPV6 yet. Every few days I'll give it another try. |

I apologize I have not posted back to try the suggestion of plugging my laptop into the cable modem directly - I will try that soon.
On a somewhat related note, I have now proven to Netgear support that something is very wrong with DNS resolution through their FVS318N device, as in frequent timeouts/lack of DNS response, regardless of the DNS server IPs specified (and regardless of DNS Proxy setting disabled) I need to see if I can get that worked out first.
Is the "future" of IPv6 to always run dual stack, as in, for the foreseeable future clients and the router must have both a IPv4 and IPv6 address? Is is not possible for me to run my inside LAN with only IPv6 addresses, and the router gets an IPv6 IP from the ISP - and yest still reach IPv4 sites? My thinking being, either in my network perimeter router, or upstream in one of the ISP's routers, they are making the "leap" or "route" between IPv6 and IPv4 for me? I see the opposite is known as "IPv6 Tunnel Broker" is there some "IPv6 Reverse Tunnel Broker" ??? Point me in the right direction so I can learn more. |

What would be the point of doing that (other than just idle curiosity to see if you can do it)? Tunnels are inherently less efficient than a direct connection and the overhead from running simultaneous IPv4 and IPv6 protocol stacks is miniscule. Most likely you were already running a dual protocol stack in the operating system on most (if not all) of your PCs anyway (whether the OS is a recent version of Windows, OS X, or a *nix variant, and whether or not your ISP supports native dual stack). |

To answer your questions...
Yes, they aren't called IPv6 Reverse Brokers but they do exist, albeit more or less at an experimental or research stage.
You won't be able to drop IPv4 entirely even on your inside network in the short term until all Internet resources are available via IPv6. For example, if you only had the IPv6 stack running on your workstation right now (no IPv4) and tried to access dslreports.com it would not work because the workstation would not believe it could reach this website since its only available via IPv4 (still). There are quirky hacks you could do to make it work "automagically", but there just isn't enough need to right now to make a solution work.
It is a good question, imo - if you have IPv6 now, do you still need IPv4... |

to ipv6huh
Update, although not related to the original problem...
After allot of back-and-forth Netgear ended up replacing the FVS318N I had - they thought there was some sort of hardware defect with the device, rather than comprehending the proof I provided that DNS packets often get "lost" leading to seemingly random timeouts and "page cannot be found" errors in the browser. Tests and proof were provided using IPv4 only and with IPv6 enabled, and it made no difference.
The brand new FVS318N they sent me has the same exact problem, regardless of the factory loaded firmware or the latest from their website.
When testing the same exact network configuration, where all other equipment is the same but only the router is changed to a Netgear FVS336Gv2 or a Cisco RV042v3 - the DNS problem is not apparent - so, I conclude, the FVS318N is still not ready for real-world implementation although it has been out for over a year.
Unfortunately for me, I liked Netgear as their devices allow for two separate networks sharing 1 public IP, essentially NAT from WAN to LAN interface, and NAT from WAN to DMZ interface which can be configured as a separate LAN including DHCP on the router.
I would love to continue testing IPv6 with the RV042v3, but it will not allow me to create a second network off the DMZ port unless I have another IP from my ISP to assign to it.
Any suggestions on a router (that isn't a $500+ Cisco ASA) that will do IPv6 and two inside networks? |

Well I'm gonna nominate a Linksys E or EA router because it supports IPv6 and now with the cloud firmware not being mandatory. I'm sure others are gonna bash my nomination for a D-Link or another Netgear though. |

Right now I have three networks, one on 2GHz, one on 5GHz and an open Guest network. |

Right now I have three networks, one on 2GHz, one on 5GHz and an open Guest network. The OP was referring to physically isolated wired ethernet network segments sharing the same internet connection (something I have done with an RV082 using different VLANs for different switch ports on the router), not wireless networks with different SSIDs. But perhaps with the help of a wireless to ethernet bridge, a wireless guest connection might work. |

I believe the RV042 shares the same firmware/interface code as the RV082, I see how I could use port-based VLANs, but all the networks were still in the same subnet - I'd really like a different IP scheme between the LAN and DMZ (or LAN2) interfaces, and the ability for firewall rules between WAN to LAN, WAN to DMZ, and DMZ to LAN (as the Netgear's did right) Am I missing something in how to accomplish this, or is the RV082 feature set different.
You are correct that I am mapping different SSIDs to different VLANs, and different VLANs to different firewall interfaces (LAN vs. DMZ) |

You are correct that I am mapping different SSIDs to different VLANs, and different VLANs to different firewall interfaces (LAN vs. DMZ) You are correct that the RV0xx series does not allow mapping different subnets to different VLANs (at least not the hardware v1 and v2 boxes... I don't know about the hardware v3 boxes). That is definitely a limitation in their VLAN implementation, but aside from sharing the same IP subnet, the different VLANs in the RV0xx architecture were definitely isolated from each other (only the RV0xx itself and the Internet were common to the different VLANs). I used to use it to provide isolated internet connectivity for PCs that I was repairing/testing, and for guest connections, so the isolation was the only thing I was interested in. |

I've seen with a Cisco WAP4410 wireless access point it allowed four isolated SSID's. It also has a bridge mode. |
