questions about ARIN ipv6 allocation
by Edvinas Kairys 13 Dec '21

13 Dec '21

Hello, We're setting up IPv6 network is USA. Our company has branches and different legal entities in EU and US. We've some ipv6 PI subnets already allocated by RIPE for EU datacenters. I have few questions: 1) Is it possible to reuse some portion of RIPE allocated ipv6 addresses in USA ? Or we need to ask for the new ones by requesting in ARIN ? 2) Can i request in ARIN just ipv6 subnets for USA DCs, but to use the same AS number which was allocated by RIPE in EU ? Thanks

Cleaning out my basement - hopefully useful to someone near IAD
by Warren Kumari 13 Dec '21

13 Dec '21

Hi all, I'm in the process of cleaning out my basement and getting rid of a bunch of networking stuff that I've accumulated over the years. Much of it is older, but I'm hoping it might be useful to someone, especially if they are doing anything like building a lab for learning/certification, etc. I'm giving it away (not selling it), and I'm in Northern VA, near IAD / Ashburn Equinix. A very partial list: Cisco 7401ASR Cisco 3560 switch Bunch of Cisco 7960 IP phones. Avaya IP phone Some Juniper M7i power supplies Wandel & Goltermann DS3/DS1 BERT / tester T-Berd 209 T1 BERT Compact PCI cards (some Nokia, some others) PCI RAID Dialogic D/120JCT-LS PCI Voice Boards Many many other similar era things Some photos: https://photos.app.goo.gl/WMSdi7k6bt3TmMBa6 Requests: 1: I'm near Dulles airport - you will have to come pick it up, and in the next few days. I'm not shipping things, etc. 2: I'd prefer that it goes to someone who will use it for learning purposes or similar (please no just taking it all to sell on eBay or similar) 3: I'd much prefer that one person take it all. It's taken me many months to get around to emptying the basement, and I'm trying to make this as easy as possible! 4: Please reply off-list (including contact information, when you can pick up, and confirmation that you would like everything) --no need to clutter up the list (as it is, this is close to what is acceptable use of the list) W -- Perhaps they really do strive for incomprehensibility in their specs. After all, when the liturgy was in Latin, the laity knew their place. -- Michael Padlipsky

Assistance with Microsoft O365 Email Deliverability?
by Tom Daly 10 Dec '21

10 Dec '21

Hi NANOG'ers, Reaching out for help - having troubles with email delivery into O365 inboxes. Have done the requisite PTRs, SPF+DKIM work, domain reputation, RBL checks, etc. For some reason, this one is vexxing me. Anyone from Microsoft on the list that could lend a helping hand? Thanks, Tom -- Tom Daly tjd(a)q7.io

Looking for a Microsoft contact for helping a long lasting email delivery problem between Google and MS 365
by Payam Poursaied 10 Dec '21

10 Dec '21

Hi Sorry guys if this message bothers you. I would really appreciate it if someone from Microsoft, from the org deals with spam/quarantine Microsoft 365 Business email service could contact me offlist. We have a long-standing email delivery problem between Google (Google Workspace) and Microsoft (Microsoft 365 Business). Since October 15th, when I found enough evidence of a problem with the Microsoft filtering system, I have gone through so many avenues. And I have documented all the communications and got nowhere. So believe me! I'm not calling for a CEO because of a tasteless cookie! Google Support does not help (and honestly could not do more. As Google's servers have delivered to MS servers) October 15th, support ticket here: http://go.microsoft.com/fwlink/?LinkID=614866 <http://go.microsoft.com/fwlink/?LinkID=614866&clcid> &clcid, support number: SR1530082617, result: technically nothing! November 10th, support ticket here: http://go.microsoft.com/fwlink/?LinkID=614866 <http://go.microsoft.com/fwlink/?LinkID=614866&clcid> &clcid, support number: SRX1531269453, result: technically nothing! November 17th, eventually, I signed up for an MS Business account to replicate the problem and escalate it within MS. So many back and forth, the last call was sending the EML, which I sent. Needless to say, sending the problematic content to the support was another mess! As those content got filtered by MS Mailserver. Ticket number 28465129. I should say the support guy is trying to do his best, but you can imagine it would be much challenging to voice up for an edge case in a large organization. I have been working in a 1K-headcount company and have seen genuine customer cases get mistreated. So I feel challenges at the size of MS. So, if anyone from MS is willing to give a hand to pinpoint the problem and get it solved, please contact me offlist. Best Regards Payam Poursaied

Latency/Packet Loss on ASR1006
by Colin Legendre 10 Dec '21

10 Dec '21

Hi, We have ... ASR1006 that has following cards... 1 x ESP40 1 x SIP40 4 x SPA-1x10GE-L-V2 1 x 6TGE 1 x RP2 We've been having latency and packet loss during peak periods... We notice all is good until we reach 50% utilization on output of... 'show platform hardware qfp active datapath utilization summary' Literally ... 47% good... 48% good... 49% latency to next hop goes from 1ms to 15-20ms... 50% we see 1-2% packet-loss and 30-40ms latency... 53% we see 60-70ms latency and 8-10% packet loss. Is this expected... the ESP40 can only really push 20G and then starts to have performance issues? --- Colin Legendre
