TFTP over anycast
by Javier Gutierrez 07 Apr '24

07 Apr '24

Hi, I'm working on some DR design and we want to not only have this site as a DR but also performing some active/active for some of the services we hosts and I was wondering if someone had some experience with using anycast for TFTP or DHCP services? What are some of the pains/challenges you experienced and things we should lookout for? Any input is greatly appreciated. Kind regards, Javier Gutierrez

List of GMAIL DNS *clients*?
by bzs＠theworld.com 29 Feb '24

29 Feb '24

Occasionally one of our log analyzers will block gmail DNS requests causing bounces when gmail claims our domain(s) are not authenticated, they can't get to our SPF etc. I'd like to whitelist them but does anyone know the list of IP blocks I need? -- -Barry Shein Software Tool & Die | bzs(a)TheWorld.com | http://www.TheWorld.com Purveyors to the Trade | Voice: +1 617-STD-WRLD | 800-THE-WRLD The World: Since 1989 | A Public Information Utility | *oo*

IPv6 connectivity to mx[1-4].smtp.goog.
by Marco Davids (Private) 27 Feb '24

27 Feb '24

Hi, At https://internet.nl we're seeing IPv6 connection issues on TCP port 25 (SMTP) to mx[1-4].smtp.goog. Either 100% DROP (so no TCP connection) or ⅔ failure to setup connection. Further testing seems to confirm the problem is bigger and on Google's side. So, this fails: echo 'quit' | nc -6 -w 3 mx1.smtp.goog. 25 and this works: echo 'quit' | nc -4 -w 3 mx1.smtp.goog. 25 (on MacOS use -G instead of -w) Is anyone else seeing this? Any idea what is causing this? -- Marco

starlink ixp peering progress
by Dave Taht 27 Feb '24

27 Feb '24

One of the things I learned today was that starlink has published an extensive guide as to how existing BGP AS holders can peer with them to get better service. https://starlink-enterprise-guide.readme.io/docs/peering-with-starlink I am curious if there is a way to see how many have peered already, how many they could actually peer with?, and progress over time since inception.... what would be the right tools for that? This is pretty impressive for peering so far: https://www.peeringdb.com/net/18747 Is there a better email list to discuss ixp stuff? -- https://blog.cerowrt.org/post/2024_predictions/ Dave Täht CSO, LibreQos

Why are paper LOAs still used?
by Seth Mattinen 27 Feb '24

27 Feb '24

Why do companies still insist on, or deploy new systems that rely on paper LOA for IP and ASN resources? How can this be considered more trustworthy than RIR based IRR records? And I'm not even talking about old companies, I have a situation right now where a VPS provider I'm using will no longer use IRR and only accepts new paper LOAs. In the year 2024. I don't understand how anyone can go backwards like that. ~Seth

Verizon Business Contact
by Richard Laager 26 Feb '24

26 Feb '24

Can someone from Verizon Business please contact me? It appears that your network is losing traffic from Verizon Wireless (e.g. 63.59.39.232, 63.56.37.4, or 63.59.67.68) to me (AS33362, e.g. to 69.89.207.16). Note that 63.59.166.100 -> 69.89.207.16 was successfully (around 2023-11-27). This breaks email between us and it's been MONTHS of VZW getting nowhere. Based on some traceroutes (on 2023-11-27 and again just now), the working ones go through 140.222.234.223 (0.ae10.GW7.CHI13.ALTER.NET) while the broken ones stop at 140.222.234.221 (0.ae9.GW7.CHI13.ALTER.NET) -- Richard Laager Wikstrom Telephone Company
