Some people need a clue by four and I'm looking to build my collection of them.
Someone on Outages was nice enough to send this about someone else's thread: https://peering.google.com/#/learn-more/faq "Google services, including Google Public DNS, are not designed as ICMP network testing services" ----- Mike Hammett Intelligent Computing Solutions Midwest Internet Exchange The Brothers WISP ----- Original Message ----- From: "Tom Beecher" <beec...@beecher.cc> To: "Mike Hammett" <na...@ics-il.net> Cc: "NANOG" <nanog@nanog.org> Sent: Tuesday, February 8, 2022 3:01:27 PM Subject: Re: Authoritative Resources for Public DNS Pinging Are there any authoritative resources from said organizations saying you shouldn't use their servers for your persistent ping destinations? I'm not sure that an ' authoritative resource ' is really needed. It should be generally understood at this point in the internet's life that networks will block / restrict some or all ICMP traffic as they need to.
