IPv6 Residential Deployment Survey
by John Curran 24 Jan '19

24 Jan '19

NANOGers - If you are providing residential Internet service with IPv6 (or are a customer of same), please take a moment to complete Jordi’s survey - this will help provide insight into the actual technical practices being used in residential IPv6 deployment. More details in attached email - Thanks! /John Begin forwarded message: From: John Curran <jcurran(a)arin.net<mailto:jcurran@arin.net>> Subject: [arin-ppml] IPv6 Residential Deployment Survey Date: May 22, 2016 at 6:24:17 AM GMT+2 To: ARIN PPML <ppml(a)arin.net<mailto:ppml@arin.net>> Folks - Jordi Palet Martínez is conducting a brief survey regarding IPv6 deployment in residential Internet service. Having insight into the various practices that are in use may help to inform IPv6 number resource policy development, and thus I ask that you take a moment to complete the survey if you are providing such services (whether production or trial basis.) Jordi notes - "The results will be published and updated every month or so - No personal data will be published. (If you know your network, it takes less than 2 minutes to complete it) The survey can be responded even if is not yet a commercial service, and customers can also respond, not just the ISP. However, to avoid duplicate data, make sure to include the country and ISP name.” The IPv6 Residential Deployment Survey may be found here - <http://survey.consulintel.es/index.php/175122> Thanks! /John John Curran President and CEO ARIN

Hulu

Could someone from Hulu reach out to me? My customers are getting the anonymous proxy page and I'm not sure why. They don't have any contact info in peeringdb and their ARIN whois looks more generic than useful (ipadmin@). ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest-IX http://www.midwest-ix.com

Quanta LB4M
by Mike Hammett 20 Apr '18

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

ticketmaster.com 403 Forbidden
by Manser, Charles J 08 Feb '18

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.

Why the internal network delays, Gmail?
by Nate Metheny 21 Jun '17

21 Jun '17

Help (and hi)! I work in higher education and we've been experiencing problems with Google delaying or queuing email for delivery to our domain. Here's some truncated email headers: ** Example 1: X-Received: by 10.237.55.65 with SMTP id i59mr10986018qtb.62.1472137448952; Thu, 25 Aug 2016 08:04:08 -0700 (PDT) Received: by mail-qt0-f175.google.com with SMTP id u25so27419242qtb.1 for <@***>; Thu, 25 Aug 2016 12:05:46 -0700 (PDT) ** Example 2: X-Received: by 10.36.1.75 with SMTP id 72mr5275579itk.40.1472130531887; Thu, 25 Aug 2016 06:08:51 -0700 (PDT) Received: by mail-it0-f48.google.com with SMTP id x131so289116132ite.0 for <@***>; Thu, 25 Aug 2016 11:50:42 -0700 (PDT) In both of these examples, these emails haven't even left Google's internal network yet; I'm getting blamed for these delays, however there is no delay in receiving these emails after they leave Google's network. Are other people having this same problem? I've tested delivery to my network from many outside sources and all SMTP requests go through without delay; this issue seems be exclusive to Google-hosted and Gmail accounts and domains. -- Nate <natemetheny(a)gmail.com>nate(a)dopedesign.com

Multi-port RFC2544/EtherSAM loopback appliance
by Jason Lixfeld 25 May '17

25 May '17

Group, I'm looking for options and opinions on a cost effective, multi-port (6'ish port SFP/SFP+) RFC2544/EtherSAM rack appliance that can act as the remote/loopback for our field installers' portable RFC2544/EtherSAM enabled Exfo test sets. I came across XenaNetworks XenaCompact which looks like it would fit the bill, but I'm sure there are others (save Ixia, Exfo and Fluke, which I'm pretty much excluding by default because I imagine they are likely completely out to lunch on price relative to the extremely simplified feature set we require). Thanks in advance.

BCP 38 coverage if top x providers ...
by Frank Bulk 24 Mar '17

24 Mar '17

My google fu is failing me, but I believe there was a NANOG posting a year or two ago that mentioned that if the top x providers would implement BCP 38 then y% of the traffic (or Internet) would be de-spoofed. The point was that we don't even need everyone to implement BCP 38, but if the largest (transit?) providers did it, then UDP reflection attacks could be minimized. If someone can recall the key words in that posting and dig it up, that would be much appreciated. Frank

BGP Route Reflector - Route Server, Router, etc
by Justin Krejci 20 Mar '17

20 Mar '17

Nanog, I am working on some network designs and am adding some additional routers to a BGP network. I'd like to build a plan of changing all of the existing routers over from full iBGP mesh to something more scalable (ie route reflection). Fortunately, I am also going to be able to decommission some older routers from the network and so shrinking the existing iBGP full mesh is something I am all too happy to spend time and energy on. For the purpose of this thread though, I am not really interested in the route reflector vs confederation discussion. In doing some research[1][2][3][4][5] I see a lot of discussions, config examples, etc on using route reflectors but most suggest picking a router, or more appropriately a set of routers, to become route reflectors within an ASN. I have not found many resources discussing using a non-router box as a route reflector (ie a device not necessarily in the forwarding path of the through traffic). I am thinking things like OpenBGPd and BIRD could make a good route reflector though they are most often discussed in the context of IXPs (ie eBGP sessions). I am wondering if people can point me in the direction to some good resource material on how to select a good BGP route reflector design. Should I just dust off some 7206VXR routers to act as route reflectors? Use a few existing live routers and just add the responsibility of being route reflectors, is there a performance hit? Install and run BIRD on new server hardware? Buy some newer purpose built routers (Cisco, Juniper, Brocade, etc) to act as route reflectors and add them to the iBGP topology? GNS3 running IOS on server hardware? Something else? How many reflectors should be implemented? Two? Four? What are the pros and cons of one design over another? On list or private off list replies would be great; I'd welcome real world experiences (especially any big gotchas or caveats people learned the hard way) as well as just links to previous discussions, PDFs, slideshows, etc. Heck even a good book suggestion that covers this topic would be appreciated.

Thanks! Justin

google ipv6 routes via cogent
by Aaron 08 Mar '17

08 Mar '17

Hi, I'm new to the nanog list, hope this isn't out of scope for what is usually discussed here. Cogent is telling me that I can't route through cogent to get to google ipv6 routes (particularly the well known dns addresses 2001:4860:4860::88xx) because google decided not to advertise those route to one of their mutual peers. Anyone know anything about this ? .and why it happened and when it will be resolved ? -Aaron

Re: WWV Broadcast Outages
by Hal Murray 06 Mar '17

06 Mar '17

"Majdi S. Abbas" <msa(a)latt.net> said: > That said, I and many others "still use" WWV -- there aren't exactly a > surplus of suitable backup methods to GPS these days. Any suggestions for gear and/or software that works with WWV (or CHU)? Or general suggestions for non GPS sources of time? Dave Mills had a driver in ntpd that used a PC audio port to listen to WWV. I don't know anybody who ever used it. I think there was code to tell some brand of receiver with a serial/USB port how to change frequencies so you could use the one that worked best for that time of day. There used to be WWVB (60 KHz) receivers. The good ones phase locked to the carrier. The general rise in EMI made those close to useless in most locations. NIST finished the job when they changed the modulation format a few years ago. As far as I know, there aren't any replacements for the old gear that take advantage of the new modulation format. GPS works too well. There are some boxes that recover the time from nearby cell phone towers. I think they will stop working as the towers get upgraded to the newer protocols that use a different form of timing. That will probably take many years. But the cell phone towers depend on GPS. (You can ususlly spot the conical antenna(s) if you look around a bit.) -- These are my opinions. I hate spam.
