I seriously doubt that any vendor would sell a product under the category "Middle Boxes". Middlebox is an abstraction (see RFC 3234?). Certain broadband access devices (oh, my, the acronym "BAD" applies here!) are real world implementations of that abstraction. At the consumer/broadband level, precision with respect to technical language is wholly disregarded in favor of something familiar (router or firewall, in this case, and remarkably so) or something that sounds impressive (the NetScream TurboAccess Millenium 4000 FX).

.SE releases report on consumer broadband routers
by Patrik Wallstrom 26 Feb '08

26 Feb '08

"Three of the ten routers that .SE has tested, have passed the test specification without any remarks. The other seven have had severe problems when using what might be considered plain Domain Name System (DNS). The majority of the routers does not manage to pass on DNSSEC to the client, which gives you problems when there are applications on the client that want to handle their own DNSSEC validation." http://iis.se/about/press?id=135 The Excel document describing the result of the tests in more detail is available on request. -- Patrik Wallström Project Manager, R&D .SE (Stiftelsen för Internetinfrastruktur) E-mail: pawal(a)iis.se Web: http://www.iis.se/

Patrik, let me be one of the first that thank you and your team for the hard work in doing this testing. Specifically as I early in this process "complained" that it was hard for us as Cisco to get to know which one (if any) of our products where involved. Thanks!

IANA introduces AAAA record for K-root
by Anand Buddhdev 13 Feb '08

13 Feb '08

Dear Colleagues, Yesterday, 4 February 2008, at around 17:00 (UTC), IANA introduced AAAA records for six of the root servers in the root server system. One of these servers is k.root-servers.net (2001:7fd::1), which is managed by the RIPE NCC. This change allows the root zone to be queried over IPv6. The K-root IPv6 prefix is currently anycast from the two global nodes, located in Amsterdam and Miami. The introduction of the AAAA records went smoothly, and we are monitoring the query rate and pattern. We are also collecting more detailed information for future analysis. A graph showing the IPv6 query rate for the last 24 hours can be viewed at: http://ripe.net/news/k-root-aaaa-announcement.html More information about AAAA records in the root zone is available at: http://www.iana.org/reports/root-aaaa-announcement.html Regards, -- Anand Buddhdev DNS Services Manager, RIPE NCC

DNSSEC trust anchors for unsigned zones
by Alexander Gall 30 Jan '08

30 Jan '08

Hi The current set of trust anchors distributed by RIPE NCC (<https://www.ripe.net/projects/disi/keys/ripe-ncc-dnssec-keys-new.txt>) includes the domains disi.nl example.net pwei.net None of these currently have any DNSSEC resource records (i.e. they are insecure), which effectively brakes those zones for everybody who uses that particular set of trust anchors. I guess this shows one of the operational problems with trust anchor management. These zones are not maintained by RIPE NCC itself and the administrators probably didn't bother to tell them that they've disabled DNSSEC (if they know or remember at all that their keys are distributed by a third party). I guess it would be more prudent for RIPE NCC to only distribute the keys for their own zones (those listed on <https://www.ripe.net/projects/disi//keys/>). -- Alex

AAAA records to be added for root servers
by Barbara Roseman 07 Jan '08

07 Jan '08

apologies for cross-posting... On 4 February 2008, IANA will add AAAA records for the IPv6 addresses of the four root servers whose operators have requested it. A technical analysis of inserting IPv6 records into the root has been done by a joint working group of ICANN's Root Server System Advisory Committee and Security and Stability Advisory Committee, a report of which can be found at http://www.icann.org/committees/security/ sac018.pdf. Network operators should take whatever steps they feel appropriate to prepare for the inclusion of AAAA records in response to root queries. More information will be posted to the IANA web site during January. Regards, Barbara Roseman IANA General OperationsManager ICANN

They have to sign (A+B+C) BTW, be aware of key tag changing if you set the revoke bit. Holger

I agree it would be unrealistic to set it for a production zone like .se yet. However, I like the idea of "exercising" the REVOKE bit so that potential developers see it. Would it break anything in BIND resolvers to do so? If not, id like to set it every time I change KSKs in our demo. -----Original Message----- From: DNSSEC deployment [mailto:dnssec-deployment@shinkuro.com] On Behalf Of Holger Zuleger Sent: Friday, January 04, 2008 1:11 AM To: DNSSEC deployment Cc: Patrik Wallstrom; Anne-Marie.Eklund-Lowinder(a)iis.se; dns-wg(a)ripe.net Subject: Re: [dnssec-deployment] Ny nyckelsigneringsnyckel (KSK) för .SE - New key signing key (KSK) for .SE Patrik Wallstrom wrote: > On Thu, 03 Jan 2008, Holger Zuleger wrote: > >>> New key signing key (KSK) for .SE >>> As from today, 2008-01-03 .SE publish and take into use a new KSK for >>> signing the .SE zone file.

Next time. Oh, sure, it's clear that no one want's to add a new functionality on a productive service without testing, even if it is just to set one bit. But I thought that it was a good time to bring rfc5011 in mind... >> Doing so enables a rfc5011 aware validator to discard the key automatically >> from the list of possible trust anchor. > > Which resolvers honors the revocation bit? To my knowledge, no swedish > resolver operators are using such software yet. I think you are right. I guess that actually no one use it. Small question to all the dnssec operators: Please raise your hand if I'm wrong. ;-) And to the bind guys: Honors bind, used as an dnssec validator, the revoke bit? Holger
