[IPv6] Solved problem w/ Firefox disabling IPv6Numerous threads have recently appeared in this forum regarding Comcast's implementation of IPv6. One of the threads which was relevant to me was the difficulty some folks had getting IPv6 to work when their network used a Netgear WNDR3700 V1 router. See: » [IPv6] Netgear WNDR3700v1 and Ipv6 IssuesThe posts by MartinC and Gerard1234 are particularly important on the second page of the thread. I did all the things recommended in their posts - update the router to firmware V1.0.16.98-dnsNA using the beta software and juggling cables, but found no joy. After much work, I found that, although Firefox 13.0 is supposed to be IPv6 aware by default, but for some reason it had network.dns.disableIPv6 in about:config set to true, so IPv6 tests failed. By double clicking on this line the boolean will be changed from true to false thus allowing Firefox to recognize IPv6. After this all the various IPv6 tests work perfectly. |

Romney2012, Ya, this is one of the tests I performed and I get the speeds I expect as I'm on the 12/2 Performance plan. It would be nice if this test had an upload speed. I noticed the ping test is broken. The netalyzr test gives something that's perhaps more useful and that is latency. I find that the latency for IPv6 is much higher than for IPv4. Probably important for gamers. Firefox has an IP precedence for IPv6 over IPv4 when both are available for a linked site. I'd like to be able to reverse that but haven't figured out how. The other tests are: » netalyzr.icsi.berkeley.edu/which gives an incredible amount of information. and » test-ipv6.comcast.net/or » test-ipv6.com/ |

Re: [IPv6] Solved problem w/ Firefox disabling IPv6Something peaked my interest and I wanted to browse to an IPV6 ready web site just using the IPV6 address instead of the name. And I was having a problem making that work until I found out you have to put the addr inside of brackets [ ] to make it work. For an example here is the facebook.com addr: » [2a03:2880:2110:3f01:fac ··· 00c:0:0][2a03:2880:2110:3f01:face:b00c:0:0] If you use this, it doesn't work: » 2a03:2880:2110:3f01:face ··· b00c:0:02a03:2880:2110:3f01:face:b00c:0:0 |

Yeah read that the other day. It's because IPv6 uses : which are normally use to specify ports in IPV4 addresses such as: 192.168.1.10:8080 Now with IPv6 you gotta use the brackets and to specify ports with those you do a: http://[2a03:2880:2110:3f01:face:b00c:0:0]:8080

Romney2012,
I presume if one's building a hosts file with IPv6 addresses one must use the brackets in the file listing. |

How do you change above to false? I have done something like this before but but can't remember how to get started. TIA |

As you were. I typed in the address bar of FF 13. "about: config". My network.dns.disableIPv6 in about:config is set to False.
When I run IPv6 test with FF 13 I get " When both protocols are available, your browser uses IPv4" |

When I run IPv6 test with FF 13 I get " When both protocols are available, your browser uses IPv4" What OS are you running. That has a bearing on what protocol is defaulted. Windows Vista & 7 make IPV6 the default if network has IPV6 turned on. Others may need some settings chgd. |

>>What OS are you running? >> Windows 7.
When I run IPv6 test with FF 13 I also get
"Your internet connection is not IPv6 capable N/A unable to contact IPv6 test server" |

"Your internet connection is not IPv6 capable N/A unable to contact IPv6 test server" Based on that response, a few things are possible: If using a router, your router either doesn't support IPV6 or it is not configured with the option on. Comcast hasn't turned on IPV6 in your area. You don't have IPV6 turned on in your PC or you disabled the IPV6 service. |

Type about:config in the location bar, aka, the Awesome Bar 3. Promise to be careful 4. Either scroll down until you find the line "network.dns.disableIPv6" or put that text in the search box to find it 5. Highlight the line headed by network.dns.disableIPv6 6. Double click the line and you'll see true change to false 7. Close the page. |

My browser went right to Facebook when I pasted [2a03:2880:2110:3f01:face:b00c:0:0] in the address bar. By the way I have a RVS4000 router. My IP mode was set on 4. I enabled IPv6. When I retested I got the same results, however the sight did put me on hold while it ran a short test. I'll just hang on and see what happens? Thanks |

Thanks If you got to Facebook.com thru the IPV6 address, then Comcast has your area up on IPV6; your router is working IPV6; your PC supports it; and the browser supports it. Looks like the only glitch you may still have is the PC or router is not handling DNS for IPV6 correctly yet. I'd concentrate the troubleshooting there. |

Hold the phone. After I enabled IPv6 on my router my partner's browser's on a Vista PC went Able Sugar. Ran the v6 test and got a warning "test taking to long check router/PC. Reset router to v4 and everything, except the partner, is back to where it was. Question: could someone please tell me how to interrogate ( dig into) the PC's? |
