BGP Experiment
by Italo Cunha 06 Feb '19

06 Feb '19

NANOG, We would like to inform you of an experiment to evaluate alternatives for speeding up adoption of BGP route origin validation (research paper with details [A]). Our plan is to announce prefix 184.164.224.0/24 with a valid standards-compliant unassigned BGP attribute from routers operated by the PEERING testbed [B, C]. The attribute will have flags 0xe0 (optional transitive [rfc4271, S4.3]), type 0xff (reserved for development), and size 0x20 (256bits). Our collaborators recently ran an equivalent experiment with no complaints or known issues [A], and so we do not anticipate any arising. Back in 2010, an experiment using unassigned attributes by RIPE and Duke University caused disruption in Internet routing due to a bug in Cisco routers [D, CVE-2010-3035]. Since then, this and other similar bugs have been patched [e.g., CVE-2013-6051], and new BGP attributes have been assigned (BGPsec-path) and adopted (large communities). We have successfully tested propagation of the announcements on Cisco IOS-based routers running versions 12.2(33)SRA and 15.3(1)S, Quagga 0.99.23.1 and 1.1.1, as well as BIRD 1.4.5 and 1.6.3. We plan to announce 184.164.224.0/24 from 8 PEERING locations for a predefined period of 15 minutes starting 14:30 GMT, from Monday to Thursday, between the 7th and 22nd of January, 2019 (full schedule and locations [E]). We will stop the experiment immediately in case any issues arise. Although we do not expect the experiment to cause disruption, we welcome feedback on its safety and especially on how to make it safer. We can be reached at disco-experiment(a)googlegroups.com.

Calling LinkedIn, Amazon and Akamai @ DE-CIX NY
by Jason Lixfeld 05 Feb '19

05 Feb '19

Hi, In late October 2018, DE-CIX announced that they would be renumbering their IPv4 address block in New York between 01-28-19 and 01-30-19. This was followed by numerous reminders in months, weeks and even days leading up to the renumbering activity. The renumbering activity has come and gone, but LinkedIn, Amazon and Akamai are still using the old IPs. If three months has gone by and the numerous reminders that have been sent have resulted in these organizations still living on the old IP space, it seems to me that there may be some sort of a disconnect between who receives the notifications from IXPs and how they are filtered upstream. I’m hopeful that the eyeballs who read this list are some of those folks who should have received the notifications from DE-CIX, or can at least filter the info back downstream to whoever can perform the renumbering activity. Thanks.

RTBH no_export
by Roel Parijs 04 Feb '19

04 Feb '19

Hello NANOG, To minimize the impact of DDoS, I have setup RTBH. For our own customers, we can set the RTBH community ourselves towards our transit suppliers and this works well. For our BGP customers the problem is more complex. Our BGP customers can send us the RTBH community, and we will drop the traffic at our borders. Since we're only running a small network, we don't have the capacity to deal with large attacks. If we would be able to forward (and maybe alter it) this RTBH community towards our upstream providers, the impact on our network would be limited. However, the RFC states that an announcement tagged with the blackhole community should get the no_advertise or no_export community. What is your opinion on this ? Thanks in advance Roel

DNS Flag Day, Friday, Feb 1st, 2019
by Brian Kantor 02 Feb '19

02 Feb '19

Quoting from the web site at https://dnsflagday.net/ What is happening? The current DNS is unnecessarily slow and suffers from inability to deploy new features. To remediate these problems, vendors of DNS software and also big public DNS providers are going to remove certain workarounds on February 1st, 2019. This change affects only sites which operate software which is not following published standards. Are you affected? On that web page, there is a Domain Owner's test. You can enter a domain name and click 'test' and shortly receive a report of what was found regarding your domain's DNS servers. I somehow managed to miss the announcement of this upcoming event, even though I read this mailing list fairly closely. Perhaps it was announced somewhere else instead. I think it needs to be mentioned here if it hasn't already been. - Brian

Effects of Cold Front on Internet Infrastructure - U.S. Midwest
by Mark Tinka 31 Jan '19

31 Jan '19

For anyone running IP networks in the Midwest, are you having to do anything special to keep your networks up? For the data centres, is this cold front a chance to reduce air conditioning costs, or is it actually straining the infrastructure? I'm curious, from a +27-degree C summer's day here in Johannesburg. Mark.
