Video: What are “Negative Trust Anchors” for DNSSEC?

What are “negative trust anchors” for DNSSEC? What function do they perform? Why do we need them? In this video, Dan York interviews Jason Livingood about his Internet-Draft on this topic and answers these and other questions:

The Internet-Draft can be found at:

http://tools.ietf.org/html/draft-livingood-negative-trust-anchors

Jason and his co-author are seeking comment and would appreciate feedback from people about this draft – does it make sense? Would you use it? Do you see any ways to improve their ideas? Their email addresses can be found at the end of the document and they are definitely open to feedback.

Jason Livingood is Vice President of Internet & Communications Engineering at Comcast and is one of the co-authors of this draft.

Deploy360@IETF86: Day 5 – MIF, LISP, IPv6 Maintenance… and we’re done!

IETF LogoAnd so we reach Friday… the final day of the 86th meeting of the Internet Engineering Task Force (IETF)  where it’s a short day that ends early and for us within the Deploy360 Programme only hits two of our topics:  IPv6 and Routing Resiliency/Security.

General information about participating remotely can be found on the Remote Participation page as well as the IETF86 agenda – specific info for the groups we are following is included below.

Here’s the preview of how we’re finishing this very busy week…

0900-1100 Friday, March 15

Multiple Interfaces (MIF) – Caribbean 1
Computers and devices today have the ability to connect to multiple networks simultaneously. Think about a laptop that can connect over WiFi or Ethernet – or a smartphone that can connect over WiFi or the cellular data network.  In those cases which network interface should the device use?  The MIF working group is working to document the existing practices and outline the issues involved in a world where multiple network availability is routine.

Location/ID Separation Protocol (LISP) – Caribbean 6
The LISP working group is defining a series of experimental RFCs around a new routing protocol designed to improve the scalability of the Internet’s routing infrastructure.

1120-1220 and 1230-1330  Friday, March 15

IPv6 Maintenance (6man) – Caribbean 4

The 6man working group “is responsible for the maintenance, upkeep, and advancement of the IPv6 protocol specifications and addressing architecture.” (quoting the charter)  This is where most of the work is happening to refine the IPv6 protocol itself, and today’s session should be quite a busy one.

With those sessions, we’ll be closing out our work at IETF 86 this week.  Some of us will then be moving into a meeting of the Internet Society Advisory Council happening on Friday afternoon before we head to the Orlando airport for our flights home.

It’s been a great week and we’ve made some significant progress on a number of fronts!

On a final note, this is the first time we’ve posted these daily previews – were they helpful?  We’d love to hear your comments – either in response to this post, on social networks or via our email or feedback form. (Thanks!)

Deploy360@IETF86: Day 1 – SIDR, Softwires and V6Ops

IETF LogoAs today’s 86th meeting of the Internet Engineering Task Force (IETF) begins, here are the sessions from the IETF86 agenda that we on the Deploy360 team will be attending (all times US Eastern).  General information about participating remotely can be found on the Remote Participation page – specific info for the groups we are following is included below.

0900-1130 Monday, March 11

There are two groups we want to follow so Jan will be probably be in one (Softwires) while I (Dan) am in the other (SIDR):

Softwires – Caribbean 2
This working group is looking at ways to connect IPv4 networks across IPv6 networks and connecting IPv6 networks across IPv4 networks… both important aspects of encouraging IPv6 deployment.

Secure Interdomain Routing (SIDR) – Caribbean 4
This is the primary working group at IETF dealing with routing security issues that we are now looking to cover in the future in our Routing Resiliency/Security section of Deploy360. There will be some good discussions here related to BGPSEC and RPKI that should be quite interesting.

1300-1500 Monday, March 11

This time block is easy as we all will be in the “v6ops” working group dealing with IPv6 operational issues. This is probably the most important working group for the IPv6 work we do here within Deploy360.

IPv6 Operations (V6ops) – Caribbean 3

1540-1710 Monday, March 11

This time block doesn’t have any sessions that are specific to the Deploy360 program, but several are of general interest:

  • History BOF – looking at ways to archive/record history of the Internet.
  • Netconf – a protocol to ease configuration of network devices
  • Oauth – an important protocol for web security
  • Transport Area – discussions of transport-related drafts and items that don’t fit in existing working groups

Links to the audio feeds and jabber rooms for those sessions can be easily found on the tools-style agenda page.

1740-1940 Monday, March 11 – Technical Plenary

The technical plenary doesn’t directly relate to the topics we cover here at Deploy360, but the lead session will be “The End of Plain Old Telephone Service (POTS)” by Henning Schulzrinne, the CTO of the US Federal Communications Committee (FCC) and should be quite interesting.

And that will be the end of a long day!

DNSSEC Discussion In DNSOP Working Group At IETF86 Next Week

IETF LogoAt the 86th meeting of the Internet Engineering Task Force (IETF) next week in Orlando there is one primary working group where DNSSEC will be discussed, the DNSOP (DNS Operations) working group.  As noted in our recently-published “Rough Guide To IETF 86′s Hot Topics“, DNSOP develops guidelines for the operation of DNS software servers and the administration of DNS zone files. It also documents DNSSEC operational procedures and looks at DNS-related IPv6 transition and coexistence issues.

The meeting is on Thursday, March 14, from 17:30 – 18:30 US Eastern time. The agenda and working group charter are:

Agenda: https://datatracker.ietf.org/meeting/86/agenda/dnsop/
Charter: https://datatracker.ietf.org/doc/charter-ietf-dnsop/

There are two major DNSSEC-related documents being discussed. First is draft-livingood-negative-trust-anchors, an interesting idea about how to use a “Negative Trust Anchor” to indicate within the DNSSEC-validating resolver that you want to accept DNS records for a given domain even if the DNSSEC-validation cames back as bad.  The primary use case for this is when there is a breakage of the DNSSEC chain of trust caused by, for instance, accidentally letting a key expire for a domain.  This idea came about from the team at Comcast when they dealt with issues like the nasa.gov key expiration.  It’s intended as a temporary measure that administrators can use while we are getting more DNSSEC deployed and the tools and processes are still evolving.

The second document is draft-kumari-ogud-dnsop-cds, a new draft that proposes a method of solving the dilemma of how to communicate a new Key Signing Key (KSK) to the parent domain using DNS itself.  This issue has been an ongoing challenge that has been in need of simplification – and this approach is one such proposal.  The mechanism, though, has proven to be quite contentious with a large volume of email to the dnsop mailing list.  It should generate quite an interesting discussion in the DNSOP meeting!

There may be a few other DNSSEC-related documents floating around in other working groups, but the DNSOP group on Thursday will be the major location of DNS-related discussion at this IETF 86 meeting.  Other DNS-related working groups such as DANE and DNSEXT chose not to meet as their work has been going on through the mailing lists and did not require a face-to-face meeting this time.

Note that if you can’t participate in person, there are several ways to participate remotely via audio, Jabber chat, WebEx and MeetEcho.

P.S. 3 of the 4 DO Team members will be at IETF 86 next week – please do say hello if you are there!

IPv6 Sessions at IETF 86 Next Week

IETF Logo

The 86th meeting of the Internet Engineering Task Force (IETF) is happening next week in Orlando and if you are interested in IPv6, there are quite a number of working groups where IPv6 will be discussed.  Our recently-published “Rough Guide To IETF 86′s Hot Topics” highlights three of the IPv6 groups:

v6ops (IPv6 Operations) WG

Joel Jaeggli is now an AD and John Brzozowski is taking over his job as WG chair along with Fred Baker. One draft to be discussed is draft-mlevy-v6ops-auto-v6-allocation-per-asn that led to some interesting discussions on the mailing list about the assertion that this draft enables networks to bypass the Regional Internet Registries (RIRs) in getting IPv6 space. It will be interesting to see whether this progresses or is discussed at the WG meeting during IETF 86.

There was a call for adoption of draft-binet-v6ops-cellular-host-requirements as a working group document. Most comments were in favor but there were a couple of articulate opponents. Many of the supporters are people working for adoption of v6 in mobile networks – mostly mobile operators.

Agenda: https://datatracker.ietf.org/meeting/86/agenda/v6ops/
Charter: https://datatracker.ietf.org/wg/v6ops/charter/
(11 March 2013, 1300-1530; 13 March 2013 1510-1710)

6man (IPv6 Maintenance) WG

The 6man Working Group is charged with the maintenance, upkeep  and advancement of the IPv6 protocol specifications and addressing architecture, which is especially relevant as IPv6 begins to be deployed around the world at scale this year. A lot of the mailing list discussion since the last IETF meeting has been around the use of the U-bit and G-bit in the IPv6 iid as outlined in draft-carpenter-6man-ug. This draft hopes to clarify the use of these bits.

Agenda: https://datatracker.ietf.org/meeting/86/agenda/6man/
Charter: https://datatracker.ietf.org/doc/charter-ietf-6man/
(15 March 2013, 1120-1220, 1230-1330)

sunset4 (Sunsetting IPv4) WG

sunset4 is a new working group in the Internet Area. The working group is an addresses the fact that the Internet is still largely IPv4, but in the presence of address exhaustion it cannot continue to be the Internet that we know today. The Internet will transition to IPv6 but there will be an interval where the Internet’s performance degrades as more coping mechanisms are adopted and before a complete transition to IPv6. This working group hopes to develop techniques to mitigate some of that pain. Sunset4 has a new charter proposed since the last IETF meeting, but it has not been approved. There has been little activity on the mailing list since IETF 85.

Agenda: https://datatracker.ietf.org/meeting/86/agenda/sunset4/
Charter: https://datatracker.ietf.org/doc/charter-ietf-sunset4/
(13 March 2013, 1300-1500)

Beyond those working groups, given that IPv6 is “the new normal” it can be found throughout many other groups, including:

IPv6-related drafts will also appear in a range of other working groups. Should be some excellent discussions and we’re looking forward to seeing progress made on a number of different drafts.

Note that if you can’t participate in person, there are several ways to participate remotely via audio, Jabber chat, WebEx and MeetEcho.
