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

You should have configured the key published with start Would it be possible to set the REVOKE Bit on that key, and announce it for another 30 days? Doing so enables a rfc5011 aware validator to discard the key automatically from the list of possible trust anchor. Without it, the key ends up in state missing on the validator side. <quote rfc5011> Missing This is an abnormal state. The key remains a valid trust- point key, but was not seen at the resolver in the last validated DNSKEY RRSet. This is an abnormal state because the zone operator should be using the REVOKE bit prior to removal. </quote> So setting the revoke bit, would be one step to make the zone more compatible to RFC5011 (Automated Updates of DNS Security Trust Anchors) which is a way forward in implementing and using DNSSEC even without a signed root (and in absence of an elsewere trustable TAR). BTW: The same is true for all other signed TLDs and the signed zones managed by RIPE as well. Greets Holger

DNS test protocol
by Patrik Wallstrom 13 Nov '07

13 Nov '07

Hi, .SE is currently performing DNS tests of consumer broadband routers as we have had problems with DNSSEC and these types of products (EDNS0 and so on). We have been running a number of tests using the attached test specification. However, we would like to broaden the scope of our tests to include non-DNSSEC specific tests such as unknown RR types. If there are more specific tests regarding ENUM or IPv6 we could do please propose them to me. We assume that AAAA works, but could include that as well. We have also decided to test if the router is an open resolver on the external interface. Please read the test protocol and give me your comments, thanks.
