Maybe not. My client's upstream just said they released the prefix to their upstreams. They had previously referenced IRRs. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest-IX http://www.midwest-ix.com ----- Original Message ----- From: "Jason Lixfeld" <jason-nanog(a)lixfeld.ca> To: "Mike Hammett" <nanog(a)ics-il.net> Cc: "NANOG list" <nanog(a)nanog.org> Sent: Monday, January 1, 2018 10:58:00 AM Subject: Re: Carrier IRR Update Frequency Cogent does IRR filtering?

I do remember that, and I know they’re capable of it. Was simply curious if anyone was aware of it actually happening (yet) this time around. ---- Andy Ringsmuth andy(a)newslink.com News Link – Manager Technology, Travel & Facilities 2201 Winthrop Rd., Lincoln, NE 68502-4158 (402) 475-6397 (402) 304-0083 cellular > On Dec 30, 2017, at 10:19 PM, Matt Harris <matt(a)netfire.net> wrote: > > This is nothing new for even moderate authoritarian states (see: Egypt during the 'arab spring' protests), and should be no surprise from a totalitarian state such as Iran. > > We've seen Iran up to no good on a global scale in the past, too, far beyond what's being suggested here: https://dyn.com/blog/iran-leaks-censorship-via-bgp-hijacks/ > So we know that they have national censorship in place. > > Are you looking for anything more specific here? > > > On Sat, Dec 30, 2017 at 9:57 PM, Andy Ringsmuth <andy(a)newslink.com> wrote: > Thought this might be a welcome change from the IPv6 waste discussion and meta-discussion. > > Seeing a few references in the news to Iran possibly cutting off Internet (at least on mobile devices) in light of significant protests around the country: > > https://www.yahoo.com/news/iran-warns-against-illegal-gatherings-protests-1… > > Was curious if anyone “in the know” has anything to back it up, etc. > > > ---- > Andy Ringsmuth > andy(a)newslink.com > News Link – Manager Technology, Travel & Facilities > 2201 Winthrop Rd., Lincoln, NE 68502-4158 > (402) 475-6397 (402) 304-0083 cellular > > > > > -- > Matt Harris - Chief Security Officer > Main: +1 855.696.3834 ext 103 > Mobile: +1 908.590.9472 > Email: matt(a)netfire.net >

Iran censorship?
by Andy Ringsmuth 31 Dec '17

Thought this might be a welcome change from the IPv6 waste discussion and meta-discussion. Seeing a few references in the news to Iran possibly cutting off Internet (at least on mobile devices) in light of significant protests around the country: https://www.yahoo.com/news/iran-warns-against-illegal-gatherings-protests-1… Was curious if anyone “in the know” has anything to back it up, etc. ---- Andy Ringsmuth andy(a)newslink.com News Link – Manager Technology, Travel & Facilities 2201 Winthrop Rd., Lincoln, NE 68502-4158 (402) 475-6397 (402) 304-0083 cellular

Wi-Fi Analyzer
by Bryan Holloway 30 Dec '17

30 Dec '17

Curious if the community has any recommendations and/or positive experiences to share for a handheld Wi-Fi (802.11a/b/g/n/ac) analyzer. Software/laptop-based solutions can be unwieldy in certain environments. However, given rave reviews, I'm open to the idea as long as it's Mac-compatible. Should be able to show detailed spectra, help locate sources of interference, have mapping capabilities, etc. Thanks!

Companies using public IP space owned by others for internal routing
by Robert Webb 30 Dec '17

30 Dec '17

Will anyone comment on the practice of large enterprises using non RFC1918 IP space that other entities are assigned by ARIN for internal routing? Just curious as to how wide spread this might be. I just heard of this happening with a large ISP and never really thought about it until now. Robert
