Asia Apac networks
by Edvinas Kairys 11 Mar '22

11 Mar '22

Hello, We've introduced Cogent network in Equinix Honk Kong DC. But seems via that link we're just receiving just only 5% of our traffic, other part of incoming traffic is received via our other ISPs like NTT, Simcentrc, and Equinix IXP. I know it's very naïve to expect the traffic load balance equally between 3 ISPs (4 if IXP is counted) using just one /24 subnet. According to most of BGP looking glasses in Asia, traffic via Cogent is least preferred even when i've added 6x prepend AS on our other mentioned providers to make route via Cogent more attractive. But nothing helps - seems main providers in Asia made routes via Cogent least preferable by lowering the local preference to it, that why prepending from our side doesn't help. Maybe someone has experience or similar problems with ISPs in Asia network ?

Fwd: Re: The role of Internet governance in sanctions

Using a few emails... - otoh, i would likely close such meager services as i provide to russian - I think it is a colossal mistake to weaponize the Internet. - Keeping the rest of the internet as functional as possible It is not "Russia" doing this. It is the Russian government doing this to the dismay of many of the Russian people. 20,000+ have already left Russia over this. If we don't keep the internet up and functional as best we can and start to block or otherwise stop/slow the flow of traffic, it is not the gov't mules that suffer, rather it is the regular, everyday Russian population that suffers. Many (most?) of the regular Russian folks want access to the global internet for info that is not gov't controlled. They can't get that with TV, radio or print media, but they can get that with the internet until the gov't blocks it. So, my 'vote' is "keep the internet up" to the best of our abilities and block/slow no one as much as possible. scott

Dear Mel & Bill: 0) Thank you for your kind advice. 1) To be honest, I am a bit of lost with multiple comments about my eMail Header at the same time. Especially, some seem not in agreement with the other. Rather than opening up a discussion thread, such as "eMail Header Rules" that for sure will distract us from the real topic on the table, I have sent a request to Valerie Wittkop (Program Director) for a copy of the "official" rules for me to follow.

Mr. Chen: Would you please stop changing the subject line with an added date stamp every time you post? It fouls threaded email readers and is most inconsiderate.

Hi, Stephen: 1) First, logistics: Since I have been waiting for the moderation of my first posting on NANOG, could I assume that you are sending me this personal eMail as a Moderator? 2) Perhaps the material provided in my writing was not sufficient, you seem to be expressing concerns from other perspectives. As concisely characterized by one of the "Internet fathers", the EzIP is an overlay network relative to the current Internet. As such, the EzIP deployment is pretty much independent of the hurdles that the current Internet equipment or convention may impose on it. That is, we can start the EzIP deployment leaving everything in the current Internet alone. This is because each EzIP deployment module, called RAN (Regional Area Network) is tethered via one IPv4 public address onto the Internet core. Since each RAN appears to be a private network, it can be set up according to its own requirements. That is, each RAN can make use of any desired IPv4 technology, while leaving others aside. As long as the packets on that single access path between the RAN and the Internet conform to the Internet conventions, the deployment of the EzIP proposal should work. 3) " ... if you plan on endpoint computers (such as those in homes) to use the 240/4 netblock. ... ": No, we do not. As presented by the RAN demonstration cited by the whitepaper, one of the primary criteria of the EzIP proposal is not to affect the current private network setups. Although, other than Windows OS based products, there are more and more IoTs do support 240/4 netblock. Even some Internet routers appear to do so, as well. 4) " ... DD-WRT project? ... ": EzIP does not have any ambition to alter or replace the existing Internet equipment in any sense. Fortunately, we can deploy our solution without such complication due to the overlay characteristics. Our main goal is to demonstrate that "*/there exists/*" one feasible configuration that can operate EzIP in parallel to the existing Internet for providing equivalent services. From such a skeletal reference, one can expand to larger deployments, as well as put on desired features and capabilities. For example, we have utilized OpenWrt 19.07.3 to demonstrate the feasibility of the EzIP scheme. Since the enabling technique is "disabling the program code that has been disabling the use of the 240/4 netblock", any other projects such as DD-WRT can replicate it just as well, if so inclined. 5) "... Firewalls ... NIST ... ": Since EzIP is only identifying the additional address resources from the "Reserve" and suggesting how to use it, I am not clear why high level functionalities such as security related firewall tasks get involved here. Do NIST Guidelines specify blocking any packet with the 240/4 netblock address? I failed to spot such. Since there is no natural division between the 240/4 netblock from the rest of IPv4 address pool, I can't see any reason to single this netblock out in the firewall related tasks anyway. Do you know the reason why? I would appreciate very much if you could elaborate your concerns. 6) By the way, the EzIP's RAN is actually very much the same as CG-NAT or CDN, architecturally. The only difference is that EzIP Project manged to identify a larger usable address pool enabling the practice of static addressing to simplify operation logistics, mitigate cyber insecurity, etc. I look forward to your thoughts.

VoLTE and SRTP
by Michael Thomas 08 Mar '22

08 Mar '22

Hi, I was reading an article on why Russia hasn't taken out Ukraine's mobile networks and one of the premises was that they could use it to eavesdrop on calls. Depending on how old their infrastructure is, that doesn't make sense as I would assume that along with e2e SIP that they'd be using SRTP with the SRTP keys exchanged using DTLS which is my understanding of the way they are secured. My understanding could be wrong though, or either outdated, or not uniformly deployed. The other thing that's weird is that the same article says they want to keep it up so they can use their bandwidth too which strikes me as sort of a crazy assumption in a war, but that's not much of an operational issue. https://www.politico.com/news/2022/03/07/ukraine-phones-internet-still-work… Mike

Fwd: Upwork Suspending Operations in Russia and Belarus
by Callan Banner 08 Mar '22

08 Mar '22

Nanog to suspend work in Belarus and Russia. How do you all feel about this? Senseless antagonization or correctly applied pressure? ---------- Forwarded message --------- From: Hayden Brown, Upwork President & CEO <upwork(a)t.upwork.com> Date: Tue, Mar 8, 2022 at 12:51 PM Subject: Upwork Suspending Operations in Russia and Belarus To: <me(a)callan.im> A message from our CEO [image: Upwork] <https://link.t.upwork.com/ls/click?upn=VqS90m2f8fx8n-2F1K6AZcGXfLgLUteWUSWn…> Dear Callan, As the world’s work marketplace, Upwork’s mission is to create economic opportunities so people have better lives. In our more than 20 years of doing business, we have worked hard to bring our marketplace to more people, with the belief that when people have the ability to innovate their careers and work, they can reach their full potential. Russian President Vladimir Putin’s war against Ukraine has challenged our mission, values, and our operational ability to bring economic empowerment to those who seek it. *Upwork has begun suspending operations in Russia and Belarus and will take full effect by May 1, 2022.* The first step will be shutting down Upwork’s support for new business generation in Russia and Belarus. Over the next few days, freelancers and clients in Russia and Belarus will no longer be able to sign up for new accounts, initiate new contracts, and be visible in search. We honor the relationships that exist between our customers and recognize the swift adjustments that they will need to make as they process this announcement. As such, existing contracts with talent and clients in the region will remain open, with final billing due by May 1, 2022. We made this decision with the utmost consideration. From the beginning of the war, Upwork has been fervently working to support the safety, security, and well-being of our many team members in the region, as well as the business needs of our customers. We fully understand the significant impact this decision has on our Upwork community in Russia and Belarus, and we want these customers to know that if and when they are able to relocate to regions where we operate, we will be eager to support them in continuing their work on our platform. Additionally, should the geopolitical situation in Russia and Belarus change, we hope to be able to resume operations. We are heartbroken and horrified by the invasion of Ukraine. Upwork is concurrently working on measures – both immediate and rolling out soon – to further support Ukrainian freelancers and the Ukrainian community, including: • A $1 million donation to Direct Relief International <https://link.t.upwork.com/ls/click?upn=VqS90m2f8fx8n-2F1K6AZcGWG3CACp-2BoZj…> in support of the Ukrainian population. • Product enhancements to make it easier for Ukrainian freelancers to preserve the careers they have worked so hard to establish, whether or not they are currently able to work. • Programs to make it easier for clients to maintain their existing relationships with and provide financial assistance to talent in Ukraine. • A $100,000 matching program for donations from our own team members to aid in humanitarian relief in Ukraine. While we continue to navigate these crucial decisions and actions, you can view communications via our Community Resources Page <https://link.t.upwork.com/ls/click?upn=VqS90m2f8fx8n-2F1K6AZcGXdU-2Bum2rQJX…>, which we are updating frequently with new developments and FAQs. Our hearts and support go out to all those affected by this senseless aggression against Ukraine. We hope that a path to peace is ahead for Ukraine, and that we are able to bring our mission back to Russia and Belarus in the future.
