abrupt speed changes and TCP
by Michael Thomas 30 Jan '20

30 Jan '20

So it occurs to me in the rollout of 5G just walking down the street you might shift back and forth between high speed 5G bands and 4G because of uneven deployment and all sorts of other reasons. It sounds like this could vary block by block practically. I assume TCP just views this as congestion? But with all of the congestion avoidance algorithms and the rapidly fluctuating bandwidth, wouldn't that result in the sender essentially adapting to the least common denominator (eg 4G)? The same goes with latency, I suppose for real time apps. Mike

Could someone from Ticketmaster or it's CDN provider reach out off list. Different IP blocks that never get the sign in window, just a spinning spiral. Thanks in advance. -- David Garland

Backup over 4G/LTE
by K MEKKAOUI 30 Jan '20

30 Jan '20

Dear NANOG Community, Can anyone help with any device information that provides redundancy for business internet access? In other words when the internet provided through the cable modem fails the 4G/LTE takes over automatically to provide internet access to the client. Thank you KARIM M.

Reaching out to Sony NOC, resolving DDoS Issues - Need POC
by Octolus Development 30 Jan '20

30 Jan '20

Hi all, We've been trying to get in contact with Sony and/or Akamai to resolve an IP blacklisting issue. Support is not useful, and our customers are complaining. If anyone has a POC for somebody over at Sony or PSN who can help us resolve these issues, it would be much appreciated! We're facing some reflected DDoS attacks, where the source address is spoofed to appear to be our IPs, and as a result getting blacklisted. Sony's support has told us to "change IPs", which just isn't realistic, so we're looking for someone actually at the NOC. Already been in touch with SNEI-NOC, which has completely ignored our emails. They only seem to respond to the normal "Account Takeover" requests, or whitelist requests. All of my IP's are already whitelisted, but there seems to be a DDoS Attack that will ban anyone's IP from Sony/PlayStation Network. Akamai's also been giving us the runaround, and told us it's purely a Sony problem, so we're trying to get to the right POC to get this issue resolved Thanks in advance!

Hawaii exchange and connection to mainland pops
by Antoni Matamalas 29 Jan '20

29 Jan '20

Hi NANOG, I'm trying to figure out how is the connectivity in the Hawaiian Islands for a project I have. I'm based in Europe and my knowledge of the details of the communications in the islands is still limited. The project is based in the O'ahu island but I'm trying to understand how things are working in the whole Hawaiian islands (pure professional curiosity). I'm focusing on two aspects: * Content delivery and connection to content providers (Google, Apple, Netflix,...) * Availability of providers that can supply wavelength between Hawaiian Islands and the continent (LA, Seattle or other locations) Doing a quick investigation I found the Aloha-IX in the PeeringDB but it looks like it doesn't have many participants and non of them appear to be a content provider. I was expecting that Hawaii being one of the major landing points of fiber in the Pacific would have some more presence of content providers and CDNs. However, I know that the total population of the island is not that much (and disperse) and maybe not enough for such kind of deployments. Also, in terms of connectivity to the continent I have not been too lucky finding providers with wavelength services. For the moment I have had some contact with GTT and NTT but not sure if there are any other regional/national providers that can also provide such services. Thanks you very much in advanced for your help! Kind regards, -- Antoni

DoD is a different animal as is UH. I work for the ILEC and can fill you in on that to a certain degree. We have the normal Google/Netflix/Akamai/etc caches. The population in the state of Hawaii is small. https://census.hawaii.gov/whats-new-releases/2019-state-population-estimates On July 1, 2019, the resident population for the State of Hawaii was 1,415,872. And of those about 1 million live on one island: Oahu. There're 5 other islands. We have a lot of trans-pacific fiber landing here, but it mostly just transits the island. Not much gets peeled off to service the state due to its size. The ILEC owns part of SEA-US: https://www.submarinenetworks.com/systems/trans-pacific/sea-us and we get service on Hawaiki for South Pacific connectivity. https://www.submarinenetworks.com/en/systems/australia-usa/hawaiki-cable Most of the inter-island fiber is owned by the ILEC, which was bought by Cincinatti Bell, which will be bought by either Brookfield Infrastructure or another company whose name isn't public yet. (Anyone been bought by BI? email me, please) As mentioned in another email HIX is the internet exchange managed by UH and DR Fortress connects to that. We do as well: http://www.hawaii.edu/hix/Hawaii_Internet_Exchange/Home.html https://www.drfortress.com/about/company-overview/ https://www.drfortress.com/services/internet-exchange/overview/ https://www.drfortress.com/services/internet-exchange/drfxchange/ https://www.drfortress.com/services/internet-exchange/peering-and-connectiv… scott

AFRINIC: The Saga Continues
by Ronald F. Guilmette 29 Jan '20

29 Jan '20

For the benefit of those of you who may have been living in caves for the past two months, I would like to share the following links regarding a massive fraud that appears to have been perpetrated by at least one AFRINIC insider. (It has still not been definitively determined if he had help or not.) https://mybroadband.co.za/news/internet/330379-how-internet-resources-worth… https://krebsonsecurity.com/2019/12/the-great-50m-african-ip-address-heist/ https://www.theregister.co.uk/2019/12/17/another_afrinic_scandal/ https://mybroadband.co.za/news/security/335226-here-are-the-police-charges-… I hate to say that I told you so, but I told you so. I reported right here on the NANOG list, in both 2016 and 2017, that there was quite a lot of funny business going on down in Africa. Nobody listened and there was no meaningful investigation whatsoever by anybody until I took it upon myself, starting in July of last year, to finally get to the bottom of this colossal mess. Here are links to my old public posts relating to this: November, 2016: https://mailman.nanog.org/pipermail/nanog/2016-November/089164.html https://mailman.nanog.org/pipermail/nanog/2016-November/089232.html https://lists.afrinic.net/pipermail/rpd/2016/006129.html August, 2017: https://mailman.nanog.org/pipermail/nanog/2017-August/091821.html https://mailman.nanog.org/pipermail/nanog/2017-August/091954.html https://mailman.nanog.org/pipermail/nanog/2017-August/092092.html AFRINIC supposedly began an investigation of these matters as early as last April (2019), but here's the funny thing: Not a single person from AFRINIC, or from any other part of what passes for "Internet governance" ever contacted me or asked a single question of me about any of this. I can only infer from this that nobody involved in this so-called investigation had any real or burning interest in gathering all of the relevant facts. In light of the facts that have now come out in the press, AFRINIC is still, allegedly, "investigating" and now, even nearly two months after the story broke in the press, AFRINIC has still not even reclaimed 100% of the valuable IPv4 space that was provably stolen from their own free pool. (Various online criminal enterprises are continuing to use that IPv4 space aqs we speak.) Worse yet, AFRINIC has done nothing whatsoever to address the problem of the large number of AFRINIC legacy /16 blocks that got stolen via some clever internal manipulation of AFRINIC's own WHOIS record. Those manipulations, and the benefits from them have flowed to various parties who are now all too well known, including one who previosuly made a brief guest apperance right here on this mailing list. In fact, that party has just recently found a brand new helpful and compliant small-time hosting provider in India to route for him the stolen 165.25.0.0/16 block, which is and has been "liberated" from its rightful owners, i.e. the City of Cape Town, South Africa. https://bgp.he.net/AS393960#_prefixes https://bgp.he.net/net/165.25.8.0/22#_whois Note that whereas AS393960 claims to be located in my own state of California, is is not incorporated here. It -is- incorporated in the state of Wyoming, but the owner and CEO, by his own admission, is actually located in Pune, India: https://in.linkedin.com/in/kushalraha (That small detail did not, of course, prevent ARIN, in its infinite wisdom, from giving the the proprietor of this place his own AS, two IPv4 /22 blocks and one IPv4 /24 block, all apparently on the basis of his tissue-thin Wyoming shell company. But I digress.) Anyway, I just wanted you all to be aware of all of these fun facts. Like I always say, just another day in paradise. Regards, rfg

RIP: Bill Manning
by Brett Watson 28 Jan '20

28 Jan '20

I was saddened to see this yesterday, that Bill Manning had passed. I was surprised this morning that it hadn’t hit NANOG yet but thought I’d post something because I have a ton of respect for Bill as I’m sure many here do. I met Bill as a very young, thought-I-knew-everything network engineer around ’92 when I was starting my internet life at a small ISP in Houston. Bill was visiting Stan Barber @ Sesquinet, which was my upstream provider at the time via T1, if I remember it all correctly. I was young, fresh out of college with a CS degree, and learning this “internet thing.” I met with Bill on campus at Rice University to discuss networking/routing, and Bill taught me CIDR, which I had no f-ing idea at that time what it was. Bill was always gracious and willing to share/teach. We always chatted and stayed in touch at NANOG and IETF conferences and through his relationship with Los Nettos over the years. Most notable, to me, was 2007 when my youngest daughter was diagnosed with cancer, and I believe Bill’s wife had (or previously battled) cancer as well. I hadn’t seen Bill for a few years, but he immediately reached out, shared his positive thoughts/prayers, and kept in touch during the battle we went through. Bill cared about people, and as noted below, he was smart as hell, and always had a crazy idea for how to solve a problem. Also as noted in Rod’s note below, Bill had a wealth of music knowledge and could always recommend something new and interesting to listen to. I’ll definitely miss Bill, and his passing makes me feel the years, and the mileage, but in a good way. -b >> This morning I talked to Julie Manning, Bill's wife.

Major issues with Cloudflare DNS (specifically DNS-over-HTTPS)
by John Von Essen 28 Jan '20

28 Jan '20

Can someone from Cloudflare contact me off-list? I work for a major search engine (not Google) and starting yesterday, we are getting reports from around the world about a DNS issue. They are either not resolving our site, or they are getting incorrect resolution (i.e. the wrong IP). The issues appears to be centered around Firefox users who have DNS-over-HTTPS enabled, with Cloudflare as the provider. Thanks John
