Fwd: IPv6 addressing: Gaps? (draft-gont-v6ops-ipv6-addressing-considerations)
by Fernando Gont 12 Feb '21

12 Feb '21

Folks, FYI. The intent is to discuss this on the IETF v6ops wg list (https://www.ietf.org/mailman/listinfo/v6ops) But comments will be appreciated, regardless of the specific channel (whether on this list, off-list, etc.) Thanks! Regards, Fernando -------- Forwarded Message -------- Subject: IPv6 addressing: Gaps? (draft-gont-v6ops-ipv6-addressing-considerations) Date: Fri, 12 Feb 2021 18:50:48 -0300 From: Fernando Gont <fgont(a)si6networks.com> To: IPv6 Operations <v6ops(a)ietf.org> Folks, In the aforementioned document (https://tools.ietf.org/html/draft-gont-v6ops-ipv6-addressing-considerations) we have tried to do at least three things: 1) Look at what we have and try to discuss things from an architectural perspective 2) Analyze the implications of #1 (whether operations, security, privacy, etc.) 3) Find missing gaps that currently prevent us from fully leveraging IPv6 addressing. Part of what we've found as doing #3 above is that: * There are shortcomings associated with the current APIs that prevent better usage of IPv6 addresses * Multi-router/multi-prefix routing seems to be broken. RFC8028 would be a fundamental starting point in the right direction... but I believe there's more to do in this area. In that light, we'd like to hear further comments on our document. And, in particular, we're interested to hear if : * there are any operational implications of IPv6 addressing that we have missed, or, * there's anything related to IPv6 addressing that you consider to be currently broken or problematic, that is missing in our I-D. Thoughts on the current contents of the I-D are, of course, also very welcome! Thanks, -- Fernando Gont SI6 Networks e-mail: fgont(a)si6networks.com PGP Fingerprint: 6666 31C6 D484 63B2 8FB1 E3C4 AE25 0D55 1D4E 7492

Anyone with experience working the Oracle Cloud and IPSec connections?
by Joseph Jenkins 12 Feb '21

12 Feb '21

We are in the process of setting up connectivity to the Oracle Cloud over ipsec connections. I have it setup with 3 /16 subnets to route back to our on premise network. The tunnel comes up when interesting traffic comes from one of the subnets, however when traffic is generated from another subnet the first subnet stops getting return traffic from OCI. Anyone with any experience that can shed some light on this?

RIPE Atlas probe available on SpaceX Starlink beta terminal
by Eric Kuhnke 12 Feb '21

12 Feb '21

https://atlas.ripe.net/probes/1001821/ I am running what I believe to be the first RIPE Atlas probe on a Starlink beta test terminal. When searching the index of public probes I did not find any other probes with "spacex" or "starlink" in the descriptions. This probe is at present not contained within AS14593 (Starlink). All beta test terminals that I am aware of right now, including my own, are in cgnat IP space and meet the public Internet via AS36492 (Google). This particular terminal is topologically closest to things at major IX points in the metro Seattle area. The absolute lowest ping time I've seen to something at the Westin is 15.85ms, with averages more often between 21-32ms. The site where this is installed will occasionally conduct other, non Atlas related tests which result in full saturation of the upstream or downstream connection, simulating a number of different types of real world use cases. This means that occasionally the RTT ping to things in Seattle may rise as high as 150ms, and artificially-induced packet loss will be introduced into the connection. Please feel free to contact me off-list with any questions.

2021.02.10 community meeting unofficial notes
by Matthew Petach 11 Feb '21

11 Feb '21

It was mentioned in the chat this morning that there was no link to slides or anything on the agenda for the community meeting that happened this morning, so I offered to share the notes I was jotting down during the meeting, to give an idea of what was covered for those in timelines not as friendly to the meeting time, or to those with conflicts. ^_^; Thanks so much to the staff, Elizabeth, Steve, and Ed for the great presentations this morning! Matt 2021.02.10 NANOG81 community meeting Speaker Edward McNair, NANOG Steve Feldman, ViacomCBS Elizabeth Culley, Comcast NOTES: Michael Voity kicks off the meeting at 0901 hours Pacific time to go over the agenda for the day. special announcements: fill out surveys! The PC reads all of them! And if you're a lucky winner, you'll get a $100 gift card! Looking for presentation proposals for NANOG82! check out sponsors at virtual expo both; sponsors have stepped up to the challenge with interesting offerings. first talk today is hosted by edward mcnair, with Elizabeth Culley and Steve Feldman. Ed Mcnair has been with nanog since 2005, and has been ED since 2018; Steve has been contributing to nanog since its inception since 1994, and has been involved with PC for the last 20 years. Elizabeth Culley is peering coordinator with comcast, and is completing her first year on the PC; this is her first time presenting to NANOG. welcome edward, steve and elizabeth, it's great to have you here. Edward takes a few moments to give some updates on the organization; strategic plan narrowed to 3 areas; education, meeting experience, online collaboration, another piece built out is the strategic timeline; encompasses from NANOG73 to NANOG 85. purpose is to see what we are aiming to achieve and what we will put forward. we always like to hear your comments, there is a feedback button that goes to NANOG staff, and he reads them all. Take a moment to honor the nanog staff; counting himself, there are 6.5 staff members, as Claudia works with them halftime. Claudia, Leigh, Valerie, Shawn, Darrieux (Dee), and Brandi all work very hard to ensure that we can have a quality program. Our 2020 annual report will be coming out soon; to give a linear record of what we've accompished over the course of 2020; we'll do polls at the end of the section; log into the polls at pollEV.com/nanog Over to Steve feldman; at end of every NANOG, there is a Program commitee get together; after SF, decided to have retreat in 2020; planned to do it in Boston or Seattle; but then things changed, and they couldn't get together in person; so they had a virtual retreat, 2 days, dec 16 2020, and jan 13 2021 to go over various items. some of the items covered: PC structure new member onboarding PC handbook update mentorship leadership review roles, responsibliities need to document them better subcommittees are we optiimizing our effort? some don't seem to do much. will add some new ones. diversity of skills and perspectives need to get people who have different industry perspectives. other topics at virutal retreat meeting format how to do hybrid meetings we optimize time for training and tutorial we focus on human interaction; need to accomodate people in different timezones. talk solicitation and selection attracting new speakers expanding the audience standardize voting content review PC's strategic vision. Liz, chairing our data analysis effort; for past 20 years, we've been building a repository of tracks, tutorials, keynote speeches, lightning talks; we have a long history of hosting the voices of those building the internet. what comes up in NANOG is often in the leading edge of technology trends; this effort will be to mine the repository, to help us keep up with the onslaught of demand. cataloging NANOG; we are recording the details of every presentation, tutoria and keynote; tagging each record with relevant metadata provide intuitive web page of popular topics porovide data to potential speakers on history of any topic which topics are asked for most often which videos are most viewed. use surveys and data on view counts to project topics that will be of most interest. looking at last 5 years of NANOG data; how many times this topic 44 topics on DNS 40 requests for automation, but 26 talks on automation Geoff Huston comes up a lot look at how many times talks are viewed on youtube; 27K views of 44 DNS talks on youtube; 26 automation videos got 77K views. A lot of people would say they're experts in a field; how can they talk about their job when it's 100% proprietary, and they can't talk about their day job; take a look at the request counts, how many presentations we get, so even doing a 101 intro class is a great way to get your feet wet. 66% of presentations are on top 20 subjects. 115 categoreis in presentations and requests match the survey requests. if we watched all the talks and presentations, 8 hours a day, it woud take 8 weeks to watch the all 550 prsentations, 357 speakers, 218 organizations. 90% of speakers present 1 or 2 times. looking forward; want to give huge thanks to Jeff Bartig, Anna Valsami, and Valerie Wittkop for doing the work to move it forwrd; and thank you to PC for creating the new data analysis committee, and providing the sunlight and support to make this a reality. we have 1300 recorded and tagged; we expect 2100 items; easy part is done, now we're getting into the hard part. Jeff Bartig wrote scripts to download from youtube; there's a lot of stuff in agendas that have to be gone through one at a time. in midst of the project; would love to hear from you; what else would you like to see? now, for polls--what topic would you like to see? and you can always put feedback in the web feedback form. Seems that Geoff Huston, IPv6, Automation, Cloud, Virtualization are hot topics! are you planning to attend minnapolis nanog82 in person? most are undecided or will attend virtually. most seem to lean to attending virtually. likewise for toronto, nanog83 it looks like most people are waiting for vaccines to be available before they will come. So far, most have not yet taken the vaccine, but also most are planning to take the vaccine once they are able to. Over to you, Michael; Thank you to Edward, Steve and Elizabeth for their time. Network Automation treasure hunt without a map is up next.

Problems with newish IP block assignment issues from ARIN
by Justin Wilson (Lists) 09 Feb '21

09 Feb '21

Folks, Have a gremlin we have been chasing around for several months now and it’s becoming a major issue as we are getting tighter on IPV4 and needing to give some provider assigned space back. In June we received a /22 from ARIN. As is my workflow I started announcing it but waited a month while I checked out the geolocation databases for correct info, did testing ,etc. All this time our test accounts could browse web-sites, etc. We put one of the pools into production and things ran good for awhile. Then we started getting the occasional web-site was not working. After several of these we started assigning the customer an IP out of one of our other ARIN blocks and the web-site would be fine and reachable. The issue seems to reside just on this /22. We have other blocks from ARIN and they are just fine. We can assign an IP out of this new block and can’t reach certain web-sites. We turn around and assign out of another block and web-site works just fine. We have two upstreams and an IX on this network. We have tried withdrawing the route on this particular /22 and isolating to one upstream alone and the problems still persist. Many of the web-sites in question are government (both state and local), online universities, and the occasional local news station. They are diverse enough to not be traced down to a common point, except the IP block. We announce the IP block via BGP the same exact way we announce the other blocks. Traceroutes show the path going the same way no matter what IP block the customer has. It acts like the IP block was blacklisted at some point and got on some bad lists but I don’t want ti limit myself to that theory. I have opened up a ticket with ARIN asking for any guidance. Has anyone ran into this with new space assigned? Any tools, sites, etc. I can use to do further troubleshooting. The IP block does not appear to have any blacklisted IPs according to MX toolbox, and some others. The block in question is 134.195.44.0/22. It has been RPKI certified and has IRR entries.
