EMail server gets blocked by Microsoft
by Dominque Roux 28 Apr '21

28 Apr '21

Hi All, is there anyone out there who has some experience with the blocking mechanism of Microsofts mail server? We're running a mail server at our company which ends up on their blacklist from time to time and we're wondering if there are some steps we could take in order to prevent this. Cheers, Dominique

TC x IRRd 4.2
by Rubens Kuhl 28 Apr '21

28 Apr '21

Hi all. TC IRR, an IRR operator focused on Brazilian networks, just changed to IRRd 4.2. The new version allowed TC to deploy RPKI validation (thanks NTT for sponsoring that development) and expose HTTPS endpoints for WHOIS and submission that we hope will foster innovation around the database. Every precaution was taken for this migration to be seamless for other IRR operators, including matching of serial numbers. Every IRR server that mirrored TC and supported -j status query was verified that it followed and still correctly follows database journals. But if anything appears broken, please let me know or e-mail db-admin(a)bgp.net.br. Thanks, Rubens

Verizon Wireless
by Chris Whelan 27 Apr '21

27 Apr '21

Hello everyone, I know this is a long shot, but I'm hoping someone on here works for Verizon Wireless or knows someone that is in a position to assist us. Recently, a change to call routing occurred and Verizon Wireless calls are now being delivered across our tandem instead of a SIP peer. Ideally, I would like to establish a SIP trunk to Verizon Wireless but changing the call flow is the short term goal. Thanks in advance for your help!

DoD IP Space
by Chris Knipe 27 Apr '21

27 Apr '21

Hi Guys, Except for the email on ARIN's details, does anyone else have a contact for the DoD? We are experiencing a situation with a 3rd party (direct peer), wanting to advertise DoD address space to us, and we need to confirm whether they are allowed to do so or not. Range in question is the 22.0.0.0/8 network, which according to ARIN is actively assigned to the DoD (US). -- Regards, Chris Knipe

Hi All, Is there anyone out there from the routing team at Twitter that could get in touch to look at some sub-optimal routing we're seeing? We've tried the Peeringdb contacts with no success. Cheers, Bob. (AS38195)

DOD prefixes and AS8003 / GRSCORP
by Siyuan Miao 26 Apr '21

26 Apr '21

Hi Folks, Just noticed that almost all DOD prefixes (7.0.0.0/8,11.0.0.0/8,22.0.0.0/8 and bunch of /22s) are now announced under AS8003 (GRSCORP) which was just formed a few months ago. It looks so suspicious. Does anyone know if it's authorized? Regards, Siyuan
