survey on BGP prefix hijacking
by Alberto Dainotti 02 May '18

02 May '18

Dear NANOG Community, BGP prefix hijacking remains a problem for Internet routing, despite the (partial) use of RPKI or detection services. We would like to hear your opinions on BGP prefix hijacking (concerns, existing defenses, needs, etc.) that would help us research new defense mechanisms both for its detection and mitigation. Please help us by answering this short (< 10min, 21 questions) and anonymous survey. Survey URL: http://tinyurl.com/hijack-survey *** The survey *** This survey is part of a joint research effort by CAIDA (www.caida.org) and the ICS-FORTH (www.ics.forth.gr) research institute, to study (a) operator awareness of BGP prefix hijacking attacks/incidents, (b) presently used defenses against BGP prefix hijacking, (c) the willingness to adopt new defense mechanisms, and (d) reasons that may hinder the deployment of BGP prefix hijacking defenses. We expect the findings of this survey to increase the understanding of existing BGP hijacking defenses and the needs of network operators, as well as help us design and implement new defense mechanisms that we will present to the operator and scientific communities. A summary of the aggregate results will be published as a part of an article/conference paper. Thank you in advance, and we look forward to your responses! Alberto (CAIDA) and Pavlos (ICS-FORTH)

Quanta LB4M
by Mike Hammett 20 Apr '18

Has anyone gotten a "non-factory" firmware to go onto these guys? There are a couple threads on Google that are inconclusive. There are rumors that it's the same as a Dell something or an HP something else, but no one has outright said, "I loaded a Dell XXXX firmware onto it and solved all of the random ass bugs." If I didn't already have a couple of stacked Extreme x400s, I'd consider these at home, but they're somewhat buggy. Quanta told me to contact whomever I bought it from... but I don't think the random guy on eBay is going to have much of anything useful to say. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest Internet Exchange http://www.midwest-ix.com

IPv4 smaller than /24 leasing?
by Filip Hruska 18 Mar '18

18 Mar '18

Hi, I have stumbled upon this site [1] which seems to offer /27 IPv4 leasing. They also claim "All of our IPv4 address space can be used on any network in any location." I thought that the smallest prefix size one could get routed globally is /24? So how does this work? [1] http://www.forked.net/ip-address-leasing/ Thanks -- Filip Hruska Linux System Administrator

TWC/Charter/Spectrum contact off-list ? (Reverse DNS issue)
by Brandon Applegate 17 Mar '18

17 Mar '18

Hello, I had success with this issue about 2 years ago when some TWC folks contacted me. I don’t know if those folks are still with TWC/Charter here in the end of 2017 - hence posting on NANOG. The tl;dr is IPv6 reverse DNS issues. It was broken, got fixed, and seems to have broken again recently. Thanks in advance. -- Brandon Applegate - CCIE 10273 PGP Key fingerprint: 0641 D285 A36F 533A 73E5 2541 4920 533C C616 703A "For thousands of years men dreamed of pacts with demons.

08 Feb '18

List, It seems that browsing to ticketmaster.com or any of the associated IP addresses results in a 403 Forbidden for our customers today. Is anyone else having this issue? If anyone from Ticketmaster could reach out to me off-list, it would be helpful.

improving signal to noise ratio from centralized network syslogs
by Joe Maimon 31 Jan '18

31 Jan '18

Hey All, Centralized logging is a good thing. However, what happens is that every repetitive, annoying but not (usually) important thing fills up the log with reams of what you are not looking for. Networks are a noisy place and silencing every logged condition is impractical and sometimes undesirable. What I am interested in is an automated zoom-in zoom-out tool to mask the repetition of "normal" events and allow the unusual to stand out. Add to that an ability to identify gaps in the background noise. (The dog that didnt bark) What I am not interested in are solutions based upon preconfigured filters and definitions and built in analysis for supported (prepopulated definitions) platforms, this is all about pattern mining/masking and should be self discoverable. Ideally a command tool to generate static versions of the analysis coupled with a web platform (with zoom +- buttons) for realtime. I made a crude run of it with SLCT, using its generated patterns to grep -v, and that in and of itself was useful, but needs a bit of work. Also, its not quite real time. Any ideas would be greatly appreciated. Joe

Leasing /22
by Ryan Gard 28 Jan '18

28 Jan '18

We're on the hunt yet again for an additional /22 to lease, and are wondering what the best options are out there? Our usual suspects that we've reached out to in the past seem to be plum out... Any recommendations? Thanks! -- Ryan Gard
