Refocusing folks work on deploying IPv6 to *everything* (rather than, say, getting that shiny new Nokia 7750 deployed so we can sell more services) costs money. Ancient boxen are out here and don't support aye pee vee six well or at all. Getting ones that do costs money. Training lower level folks takes them away from their current work and costs money.

My code was still running and no one in neteng had the knowledge of how to do anything with it much less to try to write in IPv6 sections. To take an SA and look into the networking code I wrote takes them away from things they need to do to sell services. That costs money. What Sabri wrote hit home here. Folks are not looking into it and will wait until forced to do so. Then said companies will be behind the ball in a big way, but that it what it is here and in the other companies I worked for. A lot of this read to me as flippant. You don't seem to be willing to listen to those of us out here on the raggedy edges.

IPv6 is not yet important enough to become part of that bonus target: The bonus target was normal business continuity planning... in 2008. Sorry you missed that one.

Since deploying ipv6, the cohort experienced 300% CAGR. Also, everything is mobile, and all mobile providers in the usa offer ipv6 by default in most cases. Latency! Scale! As your company launches its digital transformation iot 2020 virtualization container initiatives, ipv6 will be an integral part of staying relevant on the blockchain. Also, FANG did it nearly 10 years ago. Big content and big eyeballs are on ipv6, ipv4 is a winnowing longtail of irrelevance and iot botnets. >

Question about normal ops - BGP Flaps nightly
by Christopher Morrow 27 Nov '19

27 Nov '19

Howdy! A question of interest to me, currently, is whether it's normal for providers to cause BGP flaps to their customers nightly... This seems, in my case, to be the provider PROBABLY updating prefix-filters on my session(s). Particularly AS56554 is currently getting v4/v6 transit from 2 providers, one of which we have 2 links toward. That provider appears to flap both of our ipv6 (only) bgp peers each night at about the same time each night. This smells like: "filter updates', but something that's different than the v4 filter update? (or perhaps they have no v4 filtering to update?) In the end, should customers expect nightly (or on a regular cadence) to see their sessions bounce? It hasn't been my experience in other situations... -chris

Landing Stations used as datacenter
by Mehmet Akcin 27 Nov '19

27 Nov '19

Hey there I have been putting my thoughts on Infrapedia blog and sharing with folks like https://www.infrapedia.com/post/top20cities-datacenters I am working on a new article and this time my topic will be looking at cable landing stations(cls). Do you consider cable landing stations as a datacenter? Do you have any experience deploying a pop in CLS? Are you able to share (on or off record) your experience which I can refer as your experience (good or bad) why deploying a pop inside a CLS is good or bad idea. Any additional comments.. I am not a big fan of CLS deployments. They have limited networks ( like only carriers and no eyeballs) and very expensive connectivity (usually) Thank you in advance sharing your experience Mehmet -- Mehmet +1-424-298-1903

No matter how complex is your network (and your teams), from my humble point of view, there is always something you can do regarding IPv6. The key is not to solve one million problems on one day. The key is to go gradually, one small block after another one. You can even keep all your internal network on v4 (forever if that is your intent ) and use IPv6 on specific portions of your network. > Don't get me wrong, I'm not advocating against IPv6 deployment; on the contrary. But it is not that simple in the real corporate world. Execs have bonus targets. IPv6 is not yet important enough to become part of that bonus target: there is no ROI at this point.

I would have said the very very minimum could be to invest in a dual-stack 'proxy' for public-facing services; internal or external solution, you have the choice. And why even do that ? Because the other side is not only on IPv4. -- Willy Manga @ongolaboy https://ongola.blogspot.com/

Re: HPE SAS Solid State Drives - Critical Firmware Upgrade Required
by Stephen Cotton 26 Nov '19

26 Nov '19

HP tends to run their own firmwares on their drives especially for their blade enclosures etc. They have also had lots of bugs and vulns over the years. This isn’t the first. I know a lot of their spindle drives are hgst rebrands and their bugs don’t affect the manufacturers equivalent models. I think a lot of the ssds are either intel or Samsung rebrands. I’m glad I don’t have to manage them anymore I’ll say that. Having had debilitating firmware bug or two bite me in the past, once on the backup servers (commvault) dedup cache. ~Stephen Cotton > On Nov 26, 2019, at 3:59 PM, nanog08(a)mulligan.org wrote: > > Since this is a SSD manufacturer problem does it impact other servers that might have SSD from the same manufacturer??? > > HP hasn't said who the manufacturer is? > > Geoff > > >>> On 11/26/19 1:45 PM, Patrick W.

replaying captured traffic

I am hoping someone can provide wisdom regarding the dos and don'ts replaying captured traffic? Is open source tools sufficient? Can PCAPs be replayed? How is this accomplished? partial rewriting IP headers Recommended tools? Mike
