Help Puerto Rico use tech for social good
by Yosem Companys 08 Apr '18

08 Apr '18

Dear friends and colleagues, - How should the Puerto Rican government use technology to improve quality of life and socioeconomic development, especially in the poorest and most vulnerable communities? I would appreciate your emailing me as soon as possible one-sentence proposed actions in the format of "Do X with Y to achieve Z." Feel free to share links to any case studies or articles that may show their successful implementation elsewhere. Your proposed actions could apply to any societal sector including and not limited to: - Accountability; - Affordable access to Internet, Web, mobile, or mesh, among others; - Agriculture; - Disaster relief; - Economic growth and development; - Education and training, whether primary, secondary, higher education, vocational, or online; - Entrepreneurship; - Environment; - Food; - Health; - Housing that's affordable but can resist storms; - Jobs; - Manufacturing; - Open data; - Open governance; - Pharma/Biotech; - Privacy; - Public safety; - Security, physical or cyber; - Transportation; and, - Water. Please share with your closest 1-million friends, post on all your social media accounts, or email to all your other lists. I truly appreciate your help. Thanks, Yosem

Are any of you starting to get AI robocalls?
by William Herrin 06 Apr '18

06 Apr '18

Howdy. Have any of you started to get AI robocalls? I've had a couple of calls recently where I get the connect silence of a predictive dialer followed by a woman speaking with call center background noise. She gives her name and asks how I'm doing. The first time it happened it seemed off for reasons I can't quite articulate, so I asked: "Are you a robot or a person?" She responded "yes" and then launched in to a sales pitch. The next time I asked, "where can I direct your call?" She responded "that's good" and launched in to her pitch.

CDN-provided caching platforms?
by Russell Berg 06 Apr '18

06 Apr '18

I work for a regional Midwestern US "Tier 2" ISP that provides both wholesale and enterprise Internet connectivity. We have caching platforms in place from the likes of Akamai, Google, Netflix, and Facebook; I was wondering if there are other CDN caching platforms out there we should be researching/deploying? PM me if more appropriate... TIA Russ Russell Berg Chief Technology Officer WIN / Airstream Communications (AS 11796) P: 715-832-3726 | C: 715-579-8227 www.wins.net<http://www.wins.net/>

Why doesn't "Cloudflare 1.1.1.1" compress root answers?
by Bjørn Mork 05 Apr '18

05 Apr '18

At first I thought they had disabled compression: bjorn@miraculix:~$ dig . ns @1.1.1.1|grep SIZE ;; MSG SIZE rcvd: 431 bjorn@miraculix:~$ dig . ns @8.8.8.8|grep SIZE ;; MSG SIZE rcvd: 239 bjorn@miraculix:~$ dig . ns @9.9.9.9|grep SIZE ;; MSG SIZE rcvd: 239 But then I noticed that they *do* compress other names: bjorn@miraculix:~$ dig net ns @1.1.1.1|grep SIZE ;; MSG SIZE rcvd: 253 bjorn@miraculix:~$ dig net ns @8.8.8.8|grep SIZE ;; MSG SIZE rcvd: 253 bjorn@miraculix:~$ dig net ns @9.9.9.9|grep SIZE ;; MSG SIZE rcvd: 253 Which just makes it even more confusing. What's so special about root? Except for the obvious :-) Bjørn

NG Firewalls & IPv6
by Joe Klein 05 Apr '18

05 Apr '18

All, At security and network tradeshows over the last 15 years, I have asked companies if their products supported "IPv6". They all claimed they did, but were unable to verify any successful installations. Later they told me it was on their "Roadmap" but were unable to provide an estimated year, because it was a trade secret. Starting this last year at BlackHat US, I again visited every product booth, asking if their products supported dual-stack or IPv6 only operations. Receiving only the same unsupported answers, I decided to focus on one product category. To the gurus of the NANOG community, What are your experiences with installing and managing Next Generations firewalls? Do they support IPv6 only environments? Details? Stories? If you prefer not to disparage those poor product companies, please contact me off the list. Thanks, Joe Klein "inveniet viam, aut faciet" --- Seneca's Hercules Furens (Act II, Scene 1) PGP Fingerprint: 295E 2691 F377 C87D 2841 00C1 4174 FEDF 8ECF 0CC8

validating reachability via an ISP
by Andy Litzinger 05 Apr '18

05 Apr '18

Hi all, I have an enterprise network and do not provide transit. In one of our datacenters we have our own prefixes and rely on two ISPs as BGP neighbors to provide global reachability for our prefixes. One is a large regional provider and the other is a large global provider. Recently we took our link to the global provider offline to perform maintenance on our router. Nearly immediately we were hit with alerts that our prefix was unreachable and BGPMon alerted that nearly 80 AS's noted our route had been withdrawn. We were not unreachable from every AS, but we certainly were from some of the largest. The root cause is that the our prefix is not being adequately re-distributed globally by the regional ISP. This is unexpected and we are working through this with them now. My question is, how can I monitor global reachability for a prefix via this or any specific provider I use over time? Are there various route-servers I can programmatically query for my prefix and get results that include AS paths? Then I could verify that an "acceptable" number of paths exist that include the AS of the all the ISPs I rely upon. And what would an "acceptable" number of alternate paths be? thanks in advance, -andy
