ACTION REQUIRED: Comment to US DoC NTIA on Signing the Root
by Daniel Karrenberg 30 Jun '10

30 Jun '10

Folks, it has come to my attention that the US government is still looking for comments about the plan to sign the root. We have said we want to see this happen before, but they apparently want to hear it again. So if you want to see this happening soon, please send them a note, however short. The relavant notice is attached. Written comments may be submitted by electronic mail to DNSSEC(a)ntia.doc.gov. I would recommend copying Ashley Heineman at aheineman(a)ntia.doc.gov. If you have questions, Ashley can be reached at +1 202 482?0298. Daniel

Reverse DNS operational considerations in an IPv6 environment
by Kostas Zorbadelos 16 Jun '10

16 Jun '10

I guess this is a question suited for this WG. References to other technical forums that can address this, or any pointers to established or not operational guidelines, are highly welcome. The question has to do with the provisioning of the reverse DNS entries of customers of a broaband provider in an IPv6 environment (PTR records in ip6.arpa). In the IPv4 world, each user receives mainly a single IP. There are dynamic and static users and most providers (including us) have pre-populated PTR records in their allocations in in-addr.arpa. PTR records can point to different namespaces depending on the address space use (eg static.<domainname> and dynamic.<domainname> for static and dynamic customers respectively). In the IPv6 case the problem is obvious because of the huge IPv6 address space. Since each customer can receive a /56, this is an assignment of 2^72 possible /128 addresses which is a tremendously HUGE number. We cannot possibly have pre-populated any zone with that many entries and this is just a single customer. The main question therefore is: how can we address this issue, if we need to have reverse DNS resolution for IPv6 ranges? The first thing that comes to my mind is using wildcard records in BIND, or skipping reverse DNS alltogether. Do you know of any operational recommendations? Thanks, Kostas Zorbadelos

DNSSEC KSK Rollover Event for RIPE NCC Zones
by Anand Buddhdev 14 Jun '10

14 Jun '10

[Apologies for duplicates] Dear Colleagues, On Tuesday, 23 March 2010, the RIPE NCC published new DNSSEC trust anchors. They can be found in a new location on the RIPE website at: https://www.ripe.net/dnssec-keys/ Today the RIPE NCC has started signing all of our zones with the new keys found in those trust anchor files. If you have both the old and the new keys configured you do not need to make any changes right now. On Wednesday, 16 June, we will remove the old trust anchors from our website. With today's key rollover event the RIPE NCC has completed the migration to new DNSSEC signers. We have updated our DNSSEC Policy and Practice Statement (DPS). The updated DPS can be found at: https://www.ripe.net/rs/reverse/dnssec/dps.html During the migration we did experience a small issue. Our processes failed to pre-publish the previous Zone Signing Key (ZSK) into the zones on our new signers. While our zones were propagating to the secondary servers, some validating resolvers may have fetched signed answers and DNSKEY records from different servers, and not been able to validate these answers. However, the time-to-live on the old ZSK DNSKEY record was one hour, so the window during which validation failures could have occurred is quite small. We have taken steps to ensure that this will not happen in the future. If you have any questions or comments, please send an email to <dns-help(a)ripe.net>. Regards, Anand Buddhdev DNS Services Manager
