Before when I had my honeypot firewall off everything that crossed it's threshold, I ended up blocking myself from a variety of authoritative servers, including Google's. ----- Mike Hammett Intelligent Computing Solutions Midwest Internet Exchange The Brothers WISP ----- Original Message ----- From: "John Levine" <johnl () iecc com> To: nanog () nanog org Sent: Sunday, December 3, 2023 12:48:11 PM Subject: What are these Google IPs hammering on my DNS server? At contacts.abuse.net, I have a little stunt DNS server that provides domain contact info, e.g.: $ host -t txt comcast.net.contacts.abuse.net comcast.net.contacts.abuse.net descriptive text "abuse () comcast net" $ host -t hinfo comcast.net.contacts.abuse.net comcast.net.contacts.abuse.net host information "lookup" "comcast.net" Every once in a while someone decides to look up every domain in the world and DoS'es it until I update my packet filters. This week it's been this set of IPs that belong to Google. I don't think they're 8.8.8.8. Any idea what they are? Random Google Cloud customers? A secret DNS mapping project? 172.253.1.133 172.253.206.36 172.253.1.130 172.253.206.37 172.253.13.196 172.253.255.36 172.253.13.197 172.253.1.131 172.253.255.35 172.253.255.37 172.253.1.132 172.253.13.193 172.253.1.129 172.253.255.33 172.253.206.35 172.253.255.34 172.253.206.33 172.253.206.34 172.253.13.194 172.253.13.195 172.71.125.63 172.71.117.60 172.71.133.51 R's, John
