Level 3 Voice
by Mike Hammett 04 Jan '18

04 Jan '18

I'm looking for a contact at Level 3's voice operations, preferably someone that knows about LNP. My client didn't get a port request to approve for their customer, yet operationally their customer's number has been ported to Level 3. Their customer wasn't aware of it going elsewhere as they called my client for support on the lack of inbound calling. Thank you. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest-IX http://www.midwest-ix.com

(*cough* Linux kernel list) :) I used to gate mailing lists into cnews, and then just use tin with well-developed killfiles. Been a while though since I've touched a news system at all. (long live sizone.uucp! :) Unfortunately I haven't gotten mutt to the tin level (though collapsing threads makes reading the index easier..). (Ctrl-D to kill an entire thread in mutt btw.) Congrats on the record breaking thread! If anyone wants to TL;DR Im mildly interested in the results of this 'wisdom of the cloud' brainstorm. Certainly ipv6 is well solved by now.

Xbox Live and Teredo
by Justin Wilson 03 Jan '18

03 Jan '18

Figured the collective here might have an answer. All of a sudden a network I manage started getting complaints from XBOX live users are getting error messages about “Can’t get Teredo IP address” on their consoles. Is anyone else seeing this wide spread? The Microsoft support default answer is “Your ISP is blocking ports” when I can do an nmap on each of these customers and all of the xbox live ports are open. As an FYI these are not netted customers, but have true publics. We have tried disabling IPV6 on their interfaces and that does not seem to have helped. We have had some customers power cycle everything in their home (CPE, router, xbox) and still no go. Anyone else running into this? Does Microsoft have a higher level support for talking with ISPs at all? Justin Wilson j2sw(a)mtin.net www.mtin.net www.midwest-ix.com

AS Numbers unused/sitting for long periods of time
by James Breeden 03 Jan '18

03 Jan '18

Before I take this to the ARIN PPML, wanted to get NANOG's thoughts. I'm amazed at the number of AS numbers that are assigned, but not actively being used. I'm not talking just like they are offline for a week or month, this is complete non-use of the AS in the global routing table within *years*. They are completely abandoned resources - Whois data is inaccurate by 5-10 years, no routeviews data in the same time period, the owning organization (if you can find it) scratches their heads about responding whether they use it or not, etc. I know we're currently not in a push to get AS numbers or close to exhaustion, but I do believe that people who have global AS numbers should have a requirement to use them or return them to the global pool. Am I the only one thinking this? And before you come back with "Well they may be using it internally where it doesn't need to be in the GRT" - that's why we have Private AS numbers. I.e. some form of ARIN or global policy that basically says "If AS number not routed or whois updated or used in 24 months, said AS number can be public noticed via mailing list and website and then revoked and reissued to a pending, approved AS request" Just thinking aloud.

Spectrum prefix hijacks
by James Milko 03 Jan '18

03 Jan '18

Not sure if anyone from Spectrum is looking here at this hour, but someone is hijacking a few of your prefixes. It's causing problems in my area (NC) with reaching Google services. I'm sure there are other impacts, but that's what people are noticing. Sorry if this hits the list twice, I sent it from the wrong e-mail address the first go round. * 107.12.0.0/16 193.0.0.56 0 3333 1103 203040 10512 i *> 103.247.3.45 0 58511 203040 10512 i * 107.13.0.0/16 193.0.0.56 0 3333 1103 203040 10512 i *> 103.247.3.45 0 58511 203040 10512 i * 107.14.0.0/16 193.0.0.56 0 3333 1103 203040 10512 i Network Next Hop Metric LocPrf Weight Path *> 103.247.3.45 0 58511 203040 10512 i * 107.15.0.0/16 193.0.0.56 0 3333 1103 203040 10512 i * 103.247.3.45 0 58511 203040 10512 i

Foundry FastIron
by Mike Hammett 02 Jan '18

02 Jan '18

A client of mine has some Foundry FastIron Edge X424HFs. Brocade and Extreme don't seem overly ambitious to help. Anyone have any documentation they can scrounge up? SFP compatibility list? The ones I see in there already look substantially like the ones I get from FiberStore, but that doesn't mean much. Do they still sell support on these? I'm largely just interested in newer firmware for them. I don't think they were updated since they left the factory and there are a few quirks I'm hoping they addressed at some point. ----- Mike Hammett Intelligent Computing Solutions Midwest Internet Exchange The Brothers WISP
