I find the reliability of dslr test can be iffy with higher speed tiers. ex. your 959 Mbps is not even possible with an mtu of ~1500 (1480) as it exceeds the theoretical maximum speed.

I won't disagree. I have seen higher than 1G speeds on v4 logged, but only in bursts.

I'm comparing these to some other tests I've found, which vary from 3M to 91M for v6 and 2M  for v4 and the reverse also. At lease this is reproducible..

IPv6 Software Applications & Hardware Appliances / speed tests for ipv6
« on: October 10, 2017, 01:02:25 PM »
I have found a ( what appears to be )  reliable ipv6 speed test site.

http://www.dslreports.com/speedtest

Having used it for a couple of days, it is seems to be a reasonable test. A free login is required to enable some tests ( ipv6, as an example ) and a history, config, etc
I have a 1G connection from Verizon, using a tunnel from HE.

Ubiquiti EdgeMAX routers support fully an he tunnel. As well as ipv6 firewall.

But! only from the cli.

I agree they are blocking.

My point was that I couldn't get there using v6, but I could using v4.

My conclusion is they probably don't have v6 available from the web server.

I'm back with this problem (or a similar version of it).

I<snip>
Here's my current config (minus the "shutdown" command) for the Tunnel Interface. I'm hoping that it's not the Dialer interface causing the problem, as I'm on a dynamic IP.
Code: [Select]
configure terminal
interface Tunnel0

Try changing tunnel destination to 0.0.0.0, it may or may not work for you.

Semi off-topic, but I have no issues in reaching the site you've listed; it loads instantaneously for me.

Not for me. Not using v6 anyway. V4 works.

Verified from my desktop (using v6 ) and my blackberry ( using v4 ) to access the web site.

While not conclusive, at least is reproducible. My "best guess" is the web server won't handle v6.

General Discussion / Re: Buy more ipv6 sage shirts?
« on: May 06, 2014, 04:03:57 PM »
Mine has shrunk ( or I've gotten bigger! ), really need a larger shirt.

I am considering purchasing a Netgear Router, that appears, almost to support he.net.

The manual pages indicate that I only need the ipv4 address of the server.

Somehow I'm not convinced.

Questions & Answers / Re: Problem With LAX Tunnel
« on: February 20, 2014, 05:30:31 PM »
Good afternoon.  After four years of flawless operation, my tunnel has ceased to function.  I have changed nothing in my configuration.  I can ping my client IPv6 tunnel address (::2/64), but not the server IPv6 tunnel address (::1/64).  I have searched for any issues related to the LAX1 tunnel and have found none.  Is there anything else I can check?  Thanks!

Interesting!
I had the same problem here, today, with Verizon and the Ashburn server!

After a few hours, it started working again.

Questions & Answers / Re: Yahoo/l.yimg.com failing to load
« on: July 20, 2013, 03:22:26 PM »
Yes, it did look like a different problem, that's why I edited my comment to give more details.  I didn't want to mislead anyone.

Yahoo may not support DNS over IPv6, but they do give out IPv6 addresses for their hosts (once you wind you way through the layers of CNAMEs).

When I mentioned that the second level CNAME did not resolve, I was traversing the DNS records manually, one level at a time, trying to see where a problem might be.   

Regarding your question about caching - I don't know.    When the CNAME refused to resolve I just moved on, instead of digging into my DNS server's cache to see what was there.  When I saw the CNAME not resolving over the period of a few days (probably close to two weeks), that's when I decided to put the entry into the hosts file, and get on with my life.....    :)

Not to be buttin in where I don't know whats *really* going on, but...
CNAME trasversing seems to be simple enough.

As to yahoo DNS.  I did a dig on l.yimg.com and got this:

Dig on ipv4 shows the same, except for the ipv4 addresses.
All CNAMES were resolved.

From a  functional point of view.... l.yimg.com seems to be either an ad site or image site for ads on yahoo.

What am I not understanding?

Autoconfiguration Type:

What are the options?

DHCPv6 requires a dhcp server, which, I don't think, is in the router for ipv6 ( I have an 815 ).
If RDNSS is available, try it.

Also:

The local IPv4 address should match the tunnel ipv4 address at he.net.
On the tunnel broker page  ( create new tunnel ) it shows the ipv4 you have connected with, use that address for the router local ipv4 address and the ipv4 address of the tunnel.
( Presuming you are behind the router for the connection )

12
In the ipv6 setup page.
Do you have the following options?

Enable automatic IPv6 address assignment :   
Enable Automatic DHCP-PD in LAN :   
Autoconfiguration Type :    
Router Advertisement Lifetime :      (minutes)

If so, try checking the boxes to enabled,
set the type to SLAAC+RDNSS
and lifetime of 1440.

Just tried it. Seems to work, but I suspect it was an ipv4 connection.

IPv6 Basics & Questions & General Chatter / Sense of humor
« on: August 18, 2012, 01:04:08 PM »
Someone at UNC.EDU has a good sense of humor.

ipv6 address of 2610:28:3090:3001:dead:beef:cafe:fed7
Found it watching ipv6 traffic with wireshark.

Running a web site for "Fedora Project Spins Tracker"

Can't find a hostname or any other info to let em know their easter egg  has been found.

Just had to pass on the ip.


15
It appears I shouldn't be using the dmz function on the router and the router's tunnel functions.

Having removed the dmz and used port forwarding, everything is working properly.
