More information attached below. Thanks, John S. From: ARIN-announce <arin-announce-bounces(a)arin.net> on behalf of ARIN <info(a)arin.net> Date: Monday, April 24, 2023 at 10:39 AM To: "arin-announce(a)arin.net" <arin-announce(a)arin.net> Subject: [arin-announce] ARIN Community Grant Applications Now Open Do you have a project that needs funding, is noncommercial in nature, and benefits the Internet community within the ARIN service region? Apply now for a 2023 ARIN Community Grant. Apply at https://www.arin.net/applyforgrants. The ARIN Community Grant Program provides financial grants in support of operational or research projects that improve the overall Internet industry and Internet user environment, advance ARIN’s mission, and broadly benefit the Internet community within the ARIN region. Projects must fit into one or more of these four broad categories: - Internet technical improvements that promote and facilitate the expansion, development, and growth of the infrastructure of the Internet consistent with the public interest - Registry processes and technology improvements that help maintain a globally consistent and highly usable Internet Number Registry System - Informational outreach that advances the Internet on topics such as, but not limited to: IPv6 deployment, Internet research, and Internet governance - Research related to ARIN’s mission and operations For 2023, the ARIN Board of Trustees has approved a total expenditure of up to US$60,000 for grants of varying amounts, ranging from US$1,000 to US$20,000 based on project need. We invite you to learn more about ARIN’s Community Grant Program and to find the link to the application form at: https://www.arin.net/grants. The call for applications is open now through 2 June 2023. We encourage all applicants to clearly demonstrate how projects meet eligibility guidelines and selection criteria through the application form to improve chances of selection. ARIN looks forward to funding important projects through the ARIN Community Grant Program in 2023. Regards, American Registry for Internet Numbers

BGP Books
by Lyndon Nerenberg (VE7TFX/VE6BBM) 29 Apr '23

29 Apr '23

It has been a couple of decades since I've done any BGP in anger, but it looks like I will be jumping into the deep end again, soon, and I desperately need to get up to speed again. There seem to be a lot of good guides out there from Cisco, Juniper, and the like, but naturally they are very product oriented. What I'm looking for is more like the Stevens networking bibles (i.e. "BGP Illustrated Vol I and II"). Something that covers more than just the raw protocols, and includes things like RPKI. (The world sure has changed since the last time I was doing this!) Any/all suggestions welcome. Thanks! --lyndon

Facebook IP Geolocation
by Peter Potvin 28 Apr '23

28 Apr '23

Hey all, Recently a customer reached out to us regarding an IP of ours in Canada that Facebook is somehow placing within China, despite our geolocation in other databases showing up correctly as they're ingesting our geofeeds as we had requested. Does anyone know which geolocation databases Facebook uses, and if possible a contact at Meta we can reach out to so that this can be investigated further? Thanks in advance! Regards, Peter Potvin | Executive Director ------------------------------------------------------------------------------ *Accuris Technologies Ltd.*

Dormant space on blacklists, how can I resolve this?
by Matthew Crocker 27 Apr '23

27 Apr '23

Hello, I run Crocker Communications (AS7849) and have ARIN allocations of 161.77.0.0/16 & 66.59.48.0/20. The 66.58.48.0/20 space was used for our datacenter which shutdown a couple years ago. The space has mostly been dormant for the past couple years. I’m now starting to assign 66.59.[55-60].0/24 to a new group of residential FTTH customers. The customers are getting access denied messages from Akamai based websites. What can I do to get Akamai to unblock the 66.59.48.0/20 space. Is there a website I can look to research the reputation of the subnets? They haven’t been used in years so I would expect them to be pretty clean. Thanks -Matt

NWS service assessment on 2021 Hurricane Ida
by Sean Donelan 27 Apr '23

27 Apr '23

Just published, buried in the after-action report on 2021 Hurricane Ida Commodity internet access is now part of life-safety. National Weather Service Service Assessment August-September 2021 Hurricane Ida April 2023 https://www.weather.gov/media/publications/assessments/Hurricane_Ida_Servic… [...] The Assessment Team found commodity internet access as important to the completion of the NWS mission as the AWIPS Wide Area Network (WAN) is to disseminating life-saving warnings. The lack of reliable, consistent internet access, to include sufficient bandwidth, would have led to mission failure during Ida if not for extraordinary measures taken by staff at WFO New Orleans/Baton Rouge and the LMRFC. WFO New Orleans/Baton Rouge and the LMRFC sent people to telework from a forecaster’s home, where they had reliable commodity internet, to provide IDSS. [...]

Standard DC rack rail distance, front to back question
by Chuck Church 27 Apr '23

27 Apr '23

Hey all. Question about standard 4 post racks. We bought some that are adjustable. Unfortunately, the posts are very flimsy, as these are some fancy cabinets with spacing on the sides for vertical patch panels, etc. We found that 2 post mounting of most Cisco devices (namely Cat 9500 1RU switches) are sagging quite bad. We're used to the new server type rails that extend to support most reasonable distances front rails to back for 4 post mounting. However, for a Cisco ASA1001, there aren't rails, but rather front and back 'ears' you use to hit both front and back posts. These would appear to not have any adjustability, the front to back post distance would seem to need to match the ears, I assume they don't adjust placement on the router much. Is there a 'standard' distance between front and back rails that devices usually adhere to? Googling didn't find an answer readily. These are 19" wide cabinets by the way. Thanks, Chuck
