Survey on the use of IP blacklists for threat mitigation
by Rachee Singh 17 Jun '20

17 Jun '20

Hi NANOG community, We are a group of researchers studying the use of IP blacklists as a mechanism to mitigate security threats -- particularly over the IPv6 Internet. We would like to understand if and how you use IP blacklists to secure your networks. Please consider taking our short survey: https://forms.gle/ZEsxyiBivJAfLF7e6 The survey will be anonymous unless you choose to identify yourself. Thanks, Rachee UMass Amherst

NANOG List Maintenance Announcement
by geeks＠nanog.org 16 Jun '20

16 Jun '20

Summary During the evening on Saturday June 20, 2020 between 0300 to 0600 UTC, the NANOG Tech Committee will preform an upgrade of the mailman software and migration of archives. During this time, all mailing lists will be unavailable, including the ability to make changes to your subscription options. We expect this migration to be completed in three hours time or backed out. Detailed notes NANOG is committed to the availability of its mailing lists as the best direct member community access medium. Ongoing issues with "backskatter" and other annoyances to posters on the list are mitigated in newer versions of mailman. NANOG will be upgrading to the newest stable mailman 2.1 and enabling VERP (Variable Envelope Return Path) [1]. This will make each message to each user unique, and enable tracing bounces or other backskatter annoying emails. VERP will mean a slightly increased load on the MTA (Postfix), however in testing this was found to be a non issue. Our other addition will be to the archives. Currently all archives are split into 2011+, 1994-2011 and even older archives from the NSFNet back to 1992. All these archives will be merged and added into mailman archives. This will provide almost 30 years of archives in a single place. Should anyone have postings before 1992 please let us know, we'd like to capture them as well. Archives to be merged Attendee Jobs Members NANOG NANOG-announce Newcomers Our testing shows this merge and rebuilding the archives to take from 50-70 minutes and will be the majority of the outage time. Additional information A MOP or Method of Procedure is in-place for this maintenance with clear go/no-go steps and a back-out plan should we find any insurmountable problems. An update will be posted to the NANOG mailing list once this is completed. Any messages sent to the list during the maintenance will be queued and retried once the mailman server comes back online. This may delay some messages for a few hours, but no messages will be lost. Any questions may be directed to geeks(a)nanog.org or on-list if of interest to the community.

Hey there as the first bits started flowing through PRIX, I wanted to give a few exciting updates. Current peer lists can be found https://www.peeringdb.com/ix/2353 One of the major social media companies who have a presence in PR has committed to join PRIX. We have also started a slack channel to have better communication with onsite (in PR) people and remote folks to collaborate. You can join the slack https://join.slack.com/t/puertoricoix/shared_invite/enQtODcyMTY4ODEzMTI0LTc… not much traffic yet but here is an attached traffic exchange graph. https://ibb.co/vBS6N30 thanks, everyone for your help Mehmet

RE: Router Suggestions
by Jared Brown 16 Jun '20

My no-effort quote from last month lists just the box at $13,000. Once you are all in the total is that 1.5 multiple Baldur mentioned compared to OP. However, if you google "mx204 price" the first hit wants very much to sell you one for <$11,000. Caveat emptor and YMMV. Jared > Yes I too looked into that. And it was not near that price..

Re: ROV Deployment (was LDPv6 Census Check)

I concur. I asked our four major networks we (depaul.edu) had connectivity from if they supported ROV in early 2019. Cogent, HE.net, Internet2, and SeverCentral all said they do not and none had plans to deploy. Now two of those are doing some ROV. We've since replaced Zayo for Cogent and I asked them about it in late 2019. I know at least one of the remaining three is seriously looking at supporting it soon. Lots of reasons for the momentum, but two very noticeable reasons from my view were when AT&T announced their deployment and when Google got people worried about dropping routes. John

Re: Partial vs Full tables

From: Mike Hammett <nanog () ics-il net> Date: Fri, 5 Jun 2020 08:17:26 -0500 (CDT) > I've been wondering a similar thing for how to take advantage of the 150k - 250k hardware routes the CRS317 now has in > v7 beta. That many routes should cover the peering tables for most operators, maybe even transit's customers. Perhaps the thing you are looking for is SIR - the SDN Internet Router https://github.com/dbarrosop/sir TLDR; use pmacct to grab top N ASN speakers and install them into the FIB. Rinse and repeat. Alternatively filter out anything not from ARIN. Conveniently fits into 250k: Prefixes being announced by ARIN Region ASes: 238331 http://gregsowell.com/?p=5505 Should you want something that isn't quite so bleeding edge beta, perhaps pick up a used Arista 7050QX? It's about the same as a CRS317 and holds 144k routes. Jared
