Draytek's german support has answered my questions about the DrayTek Vigor 2130. Show stopper for me is it can have only one /64 on the inside. Minor points: DNS and NTP are not supported on v6; no RIPng. Everything else is there, so still an interesting device for the more common SOHO settings, I think.

A very cool idea is a live demo of the web configuration gui of the 2130 on their website.

The one person who raised my awareness regarding IPv6 most is a colleague, Jens Link. Other than I, he is a real IPv6 evangelist and gives talks about it here and there. He has a blog at http://blog.quux.de/. And other than mine (as of now), his is reachable via IPv6.

Someone told me about the DrayTek Vigor 2130 series, a router for home use, ready for data rates well above 100 Mbps, and IPv6. Allegedly the 2130 is capable of everything that one would want in a home router. DrayTek announces it as available probably in March, but some online shops already list it as in stock. Very interesting. If all this is true, this might be The One (SCNR) really eligible device.

Looking at a Cisco 831 and things on eBay, I stumbled upon the Cisco SB WRVS4400N router. In the last minutes I learned that SB stand for "small business" and is the former Linksys product line. That means probably no IOS, which is not necessarily a bad thing, and more or less a consumer device, although apparently an advanced one. And - tadah! - it speaks IPv6. Perhaps this is what I have been waiting for. Has wireless with up to 4 SSIDs. (Why that many? Two would have been plenty.)

According to user reviews at tom's hardware it is packed with options, but configured through a web interface. So really no IOS. Cisco says it speaks IPv6, fine. Also RIPv1 and RIPv2, but RIPng is not mentioned. Can it use more than a flat /64 on the inside? Can it make services reachable from outside? There is a "DMZ" feature mentioned, so there is some hope for the latter. Also a firewall and IDS, which is good.

Cisco has the full documentation on their web site, good. User guide says it can do router advertisments. "IP mode" can be IPv4 and Dual Stack. No IPv6 only; I could live with that. But then it gets really weird: In the user guide it looks like the device cannot speak native IPv6 over PPPoE on the WAN side; there is only mention of 6to4 tunneling. WTF?

The FAQ and Troubleshooting sections of the manual do not include anything about IPv6, but about Unreal Tournament and Half-Life. That's the spirit.

Just brought my neighbour's new shiny shiny into my network. It is a laptop running Windows 7, where IPv6 is activated by default. As soon as it saw a router advertisement, it got itself an IPv6 address and related information. Works like a charm. Joy!

Because Titan Networks has been offering native IPv6 for years, long before I was interested, I have never considered using IPv6 access via tunnels. In between there is even some choice in ISPs for IPv6, so the need for tunneling has more or less vanished.

All these ISPs can be used with T-DSL (ADSL from the Deutsche Telekom, the former state monopoly telco) for the last mile only, because this is the only last mile connection that allows a choice of ISPs. The newer alternative last mile providers like Alice/Hansenet or Arcor/Vodafone allow access only to their own Internet service.

Yesterday someone told me that AVM's Lab software version (in german) does indeed support more than one flat /64 network on the inside. According to their information it is not yet possible to make IPv6 services on the inside reachable from the outside, though. So the Fritz!Box is still too limited as an IPv6 home router.

[Update: this is no longer the case with the current version.]

Update: ligado's technical support confirmed that they do not offer customer-provided DNS reverse lookup for the fixed IPv4 address at all (only a generic standard name), so I'll cancel the account.

My news server (news.w21.org) with a few mostly regional hierarchies has IPv6 connectivity, of course :-). Of my NNTP peers, at least eight are reachable over IPv6. So I can say that I use IPv6 not only for play, but in real production. (Of course, Usenet news is mostly for play. But I digress. :-)

This is the first article of an IPv6 blog I have maintained for a few months elsewhere. I am transferring them to Dreamwidth now.

In a small scale, I am a bit of an IPv6 evangelist. At my employer's the networking group is pushing the introduction of IPv6, and I am happy to follow. They have already introduced IPv6 for the dedicated server customers, which is good. The shared web hosting, where I work, is working on it, slowly.

My home network is fully IPv6-capable, although not all devices can speak it. Most unfortunately not the Cisco 861 router, which I bought particularly because I thought it could, from information on the Cisco website (which has been corrected in between). So now my IPv6 border router is an old WRT54G that happened to be around, running OpenWRT, which is less stable and less well documented than I would like.

The mainstream home router manufacturers have not yet jumped the boat. AVM claims to be ready (see fix6.net), but waiting for the ISPs. D-Link has the DIR-825, but judging from the manual it is apparently only able to have one flat /64 network on the inside, which is not enough for me. (I have the WLAN on a separate network, so I can have it more closed than the core network.)

There is the Cisco 871, which is what I really want feature-wise, but it is a bit expensive, and I think IOS is too arcane if you don't deal with it on an everyday basis. I'd rather have a mainstream device with a point-and-click configuration tool, and cheaper, too. But apparently there is none yet, so I'll probably get an 871 from eBay or so. Or an 831, which is much cheaper, but limited to 10 Mbps on the WAN interface, so not really enough for 16 Mbps ADSL. (I have only 6 Mbps at the moment, but I have been toying with the idea of 16 Mbps for a while, mostly for the faster uplink -- 1 Mbps instead of the 512 kbps I have now.)

My infrastructure uses the domain w21.org, and I am a little proud that I even have v6 glue records for my v6 nameservers in the .org zone. Try
host -a w21.org a2.org.afilias-nst.info.

to see it. I had to make my registrar (Schlund Technologies) do it by hand because their customer service web interface is (or at least was) not yet able to handle IPv6. At all.

My current IPv6 ISP is rh-tec, who offer IPv6 Internet access over T-DSL (Deutsche Telekom) for free up to a volume of 3000 MB per month, including a /48. That is great! Less great is their interface for reverse DNS for the IPv6 addresses. I have not yet succeeded in making it accept anything, let alone a delegation for the /48, and an e-mail support request I made end of last year has not yet been answered.

With Titan Networks I had reverse DNS for my /48 delegated to me, which was fine. I made my sage certificate from HE when I used v6 with them. But they did not allow me to use v4 and v6 in two different PPPoE sessions for the same account. Of course I need two different sessions if I use a different router for each protocol. This restriction was not enforced in the beginning, so I didn't know of it initially, and learned it only after asking because my v6 and v4 connectivity had been extremely flaky for days. A question via e-mail if they could offer me any solution (like, for instance, two accounts for the two sessions) was not answered.

So I thought, I could well use another, cheaper ISP for v4 and a fixed IP address (which is not that exotic any more) and no v6 either, and found ligado. But apparently they do not offer reverse DNS even for the one IPv4 address, which makes it not really interesting. I'll have to find that out.

Rh-tec may not be willing to put much effort into reverse DNS for their freebie offer, which I could understand. But I'd rather pay for something that is actually useful. Today I found KGT new media, who have not only an IPv6 offer, but other than rh-tec also a v4 tariff that fits private home users. Both together are even cheaper than what I have from Titan. But no mention of reverse DNS either. I'll have to call them, I guess; the success rate of my e-mail inquiries has been less than satisfactory lately.
