I have a few old netblocks that were allocated to my company back in the early 2010s that our security vendor is requiring us to either secure or remove from being registered to us. I've been unable to reach anyone at ipadmin-bell(a)att.com, and the number listed isn't connected anymore. does anyone have some contact info at ATT/Bell for getting these records corrected?

Who is security-research.org ?

I noticed them in my DNS logs, trying to do AXFRs of random zones I host. The probes are coming from Hetzner, a low-cost German hosting provider with a history of tolerating dodgy customer behavior. Their website, which is hosted at Vultr, airly assures us it's nothing personal, they scan everyone to make the Internet better, just filter us, but if you insist, you can send objections to noc(a)m-d.net. Any idea who they are? I expect it's more likely that they're self-important than evil. but still, sigh. R's, John

v4 and v6 BOGON list
by Gabriel Terry 22 Mar '24

22 Mar '24

All, I was researching BOGON prefixes and found a reference from IANA listing special-purpose addresses, URLs listed below. Based on my understanding of the list I think I should be able to block all of the entries from my upstream peerings without affecting normal internet traffic. I assume that there would only be special scenarios that the addresses listed in the special-purpose entry would be used. I am interested to hear what others are doing when it comes to blocking BOGON NLRI from their upstream BGP peerings. If anyone has any insight into this please let me know your thoughts, I would love to discuss more on the topic. URLs: https://www.iana.org/assignments/iana-ipv4-special-registry/iana-ipv4-speci… https://www.iana.org/assignments/iana-ipv6-special-registry/iana-ipv6-speci… Thanks, Gabriel L. Terry

AWS Web Application Firewall blocks ISP ranges?
by Jonathan Kalbfeld 21 Mar '24

21 Mar '24

Hi All, I just became aware that AWS has a list of hosting IP providers and that list is blocked by their WAF? (!?!?). None of my VM or colo customers can reach anything in AWS, such as Docker, Twilio, etc. I confirmed through source routing that when I access it using one of my peering partners as a source IP it is reachable, but using one of my net blocks, it is not reachable and times out. Checked all of my routing tables and those AWS blocks are definitely visible. Also confirmed from looking glass that my IP ranges are showing up. Has anyone else encountered that? If so, is there a way to get removed from that list? I have a very curated list of clients and I know all of them personally and none of them have been abusing AWS, so I was wondering if it was some kind of blanket ban? If you're internal to AWS, my ASN is 54380, IP ranges affected are 199.33.244.0/24, 199.79.202.0/24, 199.188.96.0/22, 45.59.144.0/22 and 206.197.110.0/24 Feel free to reach out off-list.

Re: Best TAC Services from Equipment Vendors

Since then, I have had to go through a not insignificant evaluation period of TAC engineers > before I let them take control of a remote session, and it is now simply pure instinct to log SSH sessions. Picture it, Cisco TAC, on a troubleshooting call, runs 'no ip routing' and hits enter before our engineer could scream "NO" at 11:30AM on a core L3 on a college campus. RCA afterwards: 1. "Always log all terminals (we prefer SecureCRT) from Windows bastion host to OneDrive or Google Drive" 2. New CiscoTAC TACACS login created allowing Enable but Denying "configure" as a command. When you troubleshoot, you log in as CiscoTAC. The CiscoTAC tacacs profile description in Clearpass makes it clear why it's there. I left the curse words out. -J John C.
