IPv6 Subnetting

[Jonas]

Thanks for sharing this GG! I wasn't aware that my ISP (Bahnhof) provided IPv6, according to wikipedia .SE - (google translated) "Internet is still dominated by IPv4, and only a few percent of the Internet computers have IPv6 addresses. In Sweden there is IPv6 support from, among others Bredband2, IP-Only, SUNET, Phonera, Loopia and Bahnhof and Hi3G_Access_AB (3). In the U.S. it has been decided that all federal agencies must have some support for IPv6 by 2008." - https://sv.wikipedia.org/wiki/IPv6

However I'm puzzled, reading this article Bahnhof claim they don't provide IPv6 to end users.

http://www.zdnet.com/blog/norse-code...-the-world/103

"Johnny Aspman, chief executive officer of Bahnhof says it has IPv6 in trial mode today, but it can’t deliver IPv6 to end users until the 80-plus owners behind the 150 networks that make up Sweden’s open access last mile network swap out infrastructure to support IPv6 or dual stack.
That means networks might offer IPv6 on a business to business basis, but not a single operator in Sweden offers IPv6 to end-users commercially.

“Everybody’s talking about it, but it takes time,” says Bahnhof’s Aspman."

Does he refer to "pure" IPv6 ?


Edit; testing the links in previous posts give me IPv4 - 10/10 and IPv6 - 10/10 with Teredo, and DNS/ISP is IPv6 ready.

Most likely.

If your IPv6 address is in the 2000::/3 network (that's 2000:: to 3FFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF), then you have a publicly routable globally unique address (this constitutes one eigth of the entire IPv6 address space). Within this range are some exceptions:

• 2001::/29 - 2001:1f8::/29 is set aside for various sub-top-level aggregation (which includes the Teredo range 2001://32)
• 2001:db8://32 is for documentation purposes and is (supposed to be) explicitly non-routable
• 2002::/16 is for 6to4 (two IPv6 hosts communicating over an IPv4-only network)

Oh, and don't forget. In IPv6-land, there's no place like ::1

Wow, I've been busting my bums trying to get 10/10.

What does "ip addr" show on your box?

Hmm .. not sure I fully understand it all, networking (digital nor social lol ) have never been my strong side. I guess I'll understand later on, when trouble start cropping up

If this is what you meant;

Din publika IPv6 adress ser ut att vara 2001:0:53aa:64c:28e9:18d8:d1c4:ceb7
Din IPv6-tjänst ser ut att vara: Teredo

Is Teredo local or like a proxy ?

PS/edit; If anyone (like I had) have trouble to get IPv6 showing up at all - it may be because it's disabled in Firefox > switch value; true to false in about:config > network.dns.disableIPv6 string

Neither.

Did you install miredo from the repository? It shows itself with a dev listing of "teredo" when you use
ip addr

Miredo creates a "tunnel" between your PC and a server. When I was investigating it the server was in Germany. There is probably more than one server out there.

The tunnel created using SixXS as the serverr, and aicuu (in the repository) as a driver gives me an IPv6 address of
2001:4978:f:580::2
and at the other end of the tunnel is the address 2001:4978:f:580::1

GG - sorry missunderstood your question. installed thru repo. On mobile now away from my box. Will check when I get home in a couple of hours.

Yup, that is what I was looking for, but it doesn't show me anything that would explain why you get a 10/10. Mine looks pretty much the same except it is with aicuu and SixXS.

What does your route table look like?
sudo route -n

[GreyGeek]

mmm... That pretty much looks like mine.

Steve pretty much explained why you get a 10/10 ... it's because your ISP supports IPv6 natively. TimeWarner gives an AAAA record when I "host -t AAAA timewarnercable.com" but in reading between the lines of that "1%" support figure, it seems that they are the "business" and "premium" class users. The peasants will get IPv6 "real soon now".

My /etc/NetworkManager/system-connections/GreyGeek config file (your's will be the name you assigned to your AP) contains:

[ipv6]
method=auto
dns=2620:0:ccc::2;2620:0:ccd::2;
dns-search=opendns.com;
ignore-auto-dns=true

I added the opendns.com DNS addresses via the IPv6 tab of the NetworkManager Connections Editor. But, the opendns.com dns numbers are ignored. I've experimented with commenting out the "method" and "ignore..." lines in the four possible combinations but it doesn't help. I always get 9/10.

Ping6ing you IPv6, 2001:0:53aa:64c:28e9:18d8:d1c4:ceb7, returns nothing. I can't find your or my IPv6 address using http://ip-lookup.net/.

[SteveRiley]

The package ndisc6 includes a number of IPv6 diagnostic tools. Try running tcptraceroute6 against the OpenDNS servers.

Nice set of tools! Thanks for the heads-up! :cool:

The tool traceroute6 times out after 30 hops...

All of the sites listed relate to SixXS. I was surprised to see the 6th site, an "opendns" site. it must not work, because after than the trace times out.

[SteveRiley]

It isn't uncommon to block ICMP. Check the man pages for those tools... see if you can force either of the traceroutes to connect to destination port 53/udp. That's what a DNS server listens on.

[MoonRise]

So a 288000 in² home would have that times 23 huh? Hmmmm what can one develop in the way of super computer. Hopefully no Skynet!


For us Star Trekies, I wonder what the Borg use? Has that ever been stated?

Jonas,
I'm still trying to understand why I don't get a 10/10, i.e., why my IPv6 DNS addresses are not honored.

What do you get when you use "route -6"?

Here's what I get while running SixXS:

StixXS creates a gateway (UG) from default to the SixXS tunnel. Also, SixXS creates a "sit0" device, but it is down. I can bring it up with "ifconfig sit0 up", which then puts it into the route listing, but I have no idea what it is supposed to do. The tunnel works the same whether it is up or down, and with either I still get 9/10 on the ipv6test.

When I use miredo, on the other hand, there does NOT appear to be a gateway created, yet miredo still gives me a 9/10 on ipv6test, the same as sixxs. Here's the routing table with miredo loaded and functioning"

% Thank you for using the SixXS Whois Service

My end of the miredo tunnel, 2001:0:53aa:64c:3cef:1324:e720:544, just gives me a querying for my IPv4 endpoint, 24.223.250.187, of a Teredo IPv6 address, which is nothing more than my IPv4 IP address. Checking on the other end of the tunnel given in the /etc/miredo.conf file:

:~$ [FONT=courier new][COLOR=#ff0000]nslookup teredo-debian.remlab.net[/COLOR][/FONT]
Server:         127.0.0.1
Address:        127.0.0.1#53


Non-authoritative answer:
teredo-debian.remlab.net        canonical name = teredo.remlab.net.
Name:   teredo.remlab.net
