Is there an established method for reporting/getting removed a company with 100% false peeringdb entries?
by Eric Kuhnke 09 Mar '21

09 Mar '21

First, take a look at this: https://www.peeringdb.com/asn/18894 Now look at these (or use your own BGP table analysis tools): https://bgp.he.net/AS18894 https://stat.ripe.net/18894 The claimed prefixes announced, traffic levels and POPs appear to have no correlation with reality in global v4/v6 BGP tables. It is also noteworthy that I have inquired with a number of persons I know who are active in network engineering in NYC, and nobody has ever encountered this company.

Spoofer Report for NANOG for Feb 2021
by CAIDA Spoofer Project 08 Mar '21

08 Mar '21

In response to feedback from operational security communities, CAIDA's source address validation measurement project (https://spoofer.caida.org) is automatically generating monthly reports of ASes originating prefixes in BGP for systems from which we received packets with a spoofed source address. We are publishing these reports to network and security operations lists in order to ensure this information reaches operational contacts in these ASes. This report summarises tests conducted within usa, can.

Texas internet connectivity declining due to blackouts
by Sean Donelan 08 Mar '21

08 Mar '21

Not as bad as Myanmar (14%), Internet connectivity in Texas has been declining today. According to NetBlocks, which normally monitors government imposed outages, reports network connectivity at 68% in Texas. https://netblocks.org/ Texas operates a separate electric grid, with limited interconnections to the rest of North America. For political reasons.... For those with long memories, ENRON a Texas based corporation, once upon a time drove rolling blackouts across California in order to make billions.

25 Broadway
by Rod Beck 08 Mar '21

08 Mar '21

Hey Folks, This site used to be part of the Holy Trinity: 25 Broadway, 111 8th Avenue and 60 Hudson Telx. But I don't see many requests for it today and know at least one metro provider that pulled out. Can anyone shed some light on its current importance and any issues. My recollection is that it was owned by Telehouse. Best, R.

DPDK and energy efficiency
by Etienne-Victor Depasquale 06 Mar '21

06 Mar '21

Hello folks, I've just followed a thread regarding use of CGNAT and noted a suggestion (regarding DANOS) that includes use of DPDK. As I'm interested in the breadth of adoption of DPDK, and as I'm a researcher into energy and power efficiency, I'd love to hear your feedback on your use of power consumption control by DPDK. I've drawn up a bare-bones, 2-question survey at this link: https://www.surveymonkey.com/r/J886DPY. Responses have been set to anonymous. Cheers, Etienne -- Ing.

Re: CGNAT
by Jared Brown 04 Mar '21

Kevin, One of the presented options isn't like the others. As such the comparison isn't really fair, especially if you expect to run your business longer than 7 years. If you buy more IPv4 space you will neither have to deal with CGNAT nor worry about traffic growth. Both of those benefits are easily worth the (short term) premium. In the long term, buying more IPv4 blocks now is likely to be cheaper than running CGNAT for the foreseeable future. To echo Owen, in general, the economics today still work out to make purchasing addresses more favorable than CGNAT. - Jared Sent: Tue Feb 2314:36:48 UTC 2021 From: Kevin Burke kburke at burlingtontelecom.com To: nanog(a)nanog.org Subject: Re: CGNAT We are looking at implementing a similar solution with A10 for CGNAT. We've been in touch with A10. Just wondering if there are some alternative vendors that anyone would recommend. We'd probably be looking at a solution to support 5k to 15k customers and bandwidth up to around 30-40 gig as a starting point. A solution that is as transparent to user experience as possible is a priority. The numbers below are for a similar target of subscriber’s and peak bandwidth. We assumed a couple of numbers: Current Peak Bandwidth = 40G Remaining IPv4 traffic after migration = 20% (Seen references to 10% or 20% on this forum) Future Bandwidth Growth = 2x (no data behind this assumption) Future CGNAT’ed bandwidth = 15Gbps Equipment & budget lifecycle = 7Yr Getting that data led us to this price comparison: Solution Lifecycle/ Term Annual Cost/Sub Product Lifecycle Cost/Sub Lease IPv4 Cogent 7 $ 4.45 $ 31.13 A10 CGNAT 15Gb 7Yr 7 $ 1.21 $ 8.47 A10 CGNAT 40Gb 7Yr 7 $ 1.95 $ 13.68 Purchase @ $25 7Yr 7 $ 3.57 $ 25.00 The current plan is implement an A10 CGNAT solution after upgrading our network for IPv6. In the interim we will have to lease IPv4 to tide us over. I would be curious to see what other’s estimate the costs of various approaches. Feel free to ping me off-list for more specific numbers.
