[IPv6] IPv6 Comcast Speedtest

I figure I'd revive the thread here »[IPv6] Comcast Speedtest to see what changes if any have been made to the IPv6 Comcast speedtest site here »ipv6.speedtest.comcast.net/
Unfortunately from what I've seen, the same problems remain. There still seems to be an issue where it doesn't zero in on your general location upon loading the site like the IPv4 version and the site still seems to claim that the test is IPv4 instead of IPv6 as shown here »stage.results.speedtest.comcast.···9962.png

This is a problem with the IPv6 geolocation data. It'll take time until all of the geo-ip databases have the correct locations for their v6 blocks.

To put this in perspective, my the geo ip databases think my v4 block is in CT.

But it's been several months now, shouldn't this have all have been sorted out by now?

What I mean is that when I launch the IPv4 version it shows me the Northeast US and it's servers. The IPv6 version just shows me the entire United States and all the servers.

Mike Wolf See Profile,

I am seeing the same thing that you are. When I go to Comcast's IPv4 speed test site, it tells me that my Recommended Server is Chicago IL, and zooms / centers the map to that location. I am of course free to move the map around and pick another test location.

With the IPv6 version, it shows the whole map, does not indicate a "Recommended Location", and as you pointed out, the box at the end of the test still lists "IPv4". I had to look at it for a bit to see what you were talking about in regards to that. But, after looking at the screen, and my own results, I did see it.

On a side note, I did get IPv6 working again (upgraded to a newer beta build of PFSense from the 12th) and that fixed my problem.

strange.. it loaded up for me showing PA / northeast sites.. I still had to chose a server (no recommended server was listed) but at least it was in the right area.. as far as the results showing IPV4, I'd bet that they never bothered to update the icon to say IPV6.. If you look at the whole test page in the upper right you should see your client IP listed as the IPV6 address:

Yeah I do see my IPv6 address in the upper right corner like in your picture, but alas I don't know why nothing has changed, nothing was fixed, over all this time.

It has me at almost 8000 miles from San Jose, oops lol I'm actually 170 miles northwest of it. Since it thinks I'm halfway around the world, it doesn't recommend any servers, unlike the IPv4 one, which correctly recommends the San Jose server.

Edit-It does show my proper IPv6 address at the top right of the test window. Our CMTS is in Ukiah, about 8 miles south of me.

I did not notice that part before, so I re-ran the test for me, and picked the Chicago Server.

It says that I am 6,100 miles from Chicago! In reality, I'm only about 40 miles northwest of downtown Chicago as the crow flies.

I don't know exactly how all this works, but I do believe whfsdude See Profile's explanation is the reason the functionally between Comcast's IPv4 speedtest and their IPv6 one, as far as centering the map, and showing the distance from the test server, is not working.

said by whfsdude:

This is a problem with the IPv6 geolocation data. It'll take time until all of the geo-ip databases have the correct locations for their v6 blocks.

Again, I have no idea what is actually involved with that, and why its taking so long to get it fixed (or have it auto-correct itself), but that would see like the logical answer here.

Why has no one noticed that you just need to divide the distance by 100?

How does "100" work exactly with the tests posted above? Close, but still not accurate.

In my case, dividing the IPv6 test 6050 mile distance by 100 is actually a lot closer than the IPv4 150 mile distance. I am actually located about 40 miles from the downtown business district in Nashville.

I'm still wondering why no one from Comcast has commented on here officially. It's like they've forgotten about this issue.

I think that Comcast does not consider the »ipv6.speedtest.comcast.net site to be officially open to the public, and they are concentrating on more important IPv6 issues.

Have you found any official link to the site anywhere on another Comcast site (such as their Comcast's IPv6 Information Center or the IPv4 speed test site)? The only place I have seen links to »ipv6.speedtest.comcast.net has been in forums.

Ok you can get to them, but what is the result? Does it display both your IPv4 IP and IPv6 IP's? Also, what kind of score do you have?

See the screen shot of what I'm talking about.

Also, both of those sites are using IPv4 ip's (see below)

nslookup www.test-ipv6.com
Server:  pfsense.localdomain
Address:  192.168.1.1
 
Non-authoritative answer:
Name:    test-ipv6.com
Address:  216.218.228.114
Aliases:  www.test-ipv6.com
 
nslookup www.test-ipv6.comcast.net
Server:  pfsense.localdomain
Address:  192.168.1.1
 
Non-authoritative answer:
Name:    www.test-ipv6.g.comcast.net
Address:  69.252.76.81
Aliases:  www.test-ipv6.comcast.net
 

So even if you can get to them, does not mean that IPv6 is working for you. Everyone should be able to get to them as they are not IPv6 only sites! :)

I can also access other IPv6 sites just fine.

Ok I saw that, but it just looked different then what I see when I go to that page is all, which is why I asked.

And, I see you can get to Google's IPv6 site, so that means IPv6 is indeed working for you. Sorry if I made it out like that was the problem, I just did not think it was based on the results you had provided (again, being different from what comes up on the screen for me on those two sites).

What happens if you try to do a trace route to the Comcast IPv6 speed test site? My results are below

I will say though, after paying closer attention, that the test is doing something weird. When doing the IPv6 portion, the v6 IP it shows keeps alternating between my host IP and the IP of my router and eventually the final is the router IP. THat may have something to do with it.

Will keep looking.

Yeah, that does not sound right. I know if I go to this page

»www.test-ipv6.com/

and reload it over and over, I always get the same IPv6 IP being shown, which matches what my Windows 8 Desktop reports as the "Temporary IPv6 Address" shown when I run an ipconfig/all.

Just making sure that you know you're using an IPv6 tunnel to SixXS and not Comcast native.

I can get to the »www.test-ipv6.comcast.net/ site, and I get two 10/10's. I cannot get to the Comcast IPv6 speedtest site, though. It just times out.

I wonder if Comcast is restricting their speedtest site to Comcast IPv6 only --- I am using a he.net tunnel for IPv6.

I think Comcast is having IPV6 problems today. I can't get to the IPV6 speedtest site, and I have been able to in the past. Also, the readiness check shows that ipv6 sites are all timing out, and I get 0/10 where I previously had 10/10. My router does show DHCP with an IPV6 2601: address on the WAN, and 2001: on the LAN, so that part is working.

Okay...this may or may not be related. I set up a tunnel via HE and I seem to have lost it. I double checked all of the settings including the IP address from Comcast and it's all correct on HE's site and my router.
So are there people out there experiencing the same with their IpV6 tunnels or is this just happening with native IPv6? I don't have native IPV6 due to the on going work with Comcast and Cisco. I have a DP3008 modem. Thanks.

Well, I just checked things on my end.

For my router (PFSense 2.1 beta build) I am getting on the WAN side an IPv6 IP of 2001:558:.... The subnet mask on the WAN side is 128. For the LAN side, the IPv6 IP is 2601:d:4c00.... with a subnet mask of 64.

I can get to all three of these pages without problems
Comcast's IPv6 Speed Test: »ipv6.speedtest.comcast.net/
General "Test Your IPv6" site: »www.test-ipv6.com/
Comcast's IPv6 Test site: »www.test-ipv6.comcast.net/

Both of the test sites return 10/10. The IPv6 IP that is shown on all three is the same, and is 2601:d:4c00..... That also matches exactly what my ipconfig/all shows for my "Temporary IPv6 Address" on my desktop (which is the computer that I accessed all sites from).

So, as far as I can tell, things are working the way they should be for me, and without any problems.

It must be on my end then. Guess I have to do a little more diagnostic work. Thanks. If I can't get it to work I'll just delete it and reconfig it.

Edit...I figured out my problem with the HE Tunnel. I Googled my problem and found out when I up graded my AEBS to v.7.6.3 is broke the tunnel path. I down graded back to 7.6.1 and everything works fine again. So until Apple gets their act together on a fix. I'll leave as it.
