The local ILEC (Verizon) use Colt 250+. They are pretty cool. They do not do layer 3 like the meter you referenced. I'm actually looking for a cost-effective meter that does ADSL+ / VDSL2 / e.SHDSL. it's easy to find one that does the first two, but not all three. -------- Original message -------- From: Lyndon Nerenberg <lyndon(a)orthanc.ca> Date: 06/29/2015 5:50 PM (GMT-08:00) To: North American Network Operators' Group <nanog(a)nanog.org> Subject: Thoughts On Cheap Chinese xDSL Testers I've been poking around looking for an inexpensive xDSL circuit tester to do some measurements on my home DSL line, in opposition to the telco. $2K+ is not in the budget, so I'm curious about the accuracy of the $300 Chinese units kicking around eBay (e.g. the ST332B).

Re: How long will it take to completely get rid of IPv4 or will it happen at all?

Before that will happen. Isp's will first try cgnat and the alikes. They rather spend money on hardware supporting that then make the networks dualstack. Why? you may ask. Simple. Most customer service centers have ppl with less then basic skills. Explaining how ipv4 even looks like took them long enough. Abuse ticket systems and logparsers are probably also v4 based. And the one who wrote them, probably got fired and replaced by a younger/cheaper guy who just got out of school with no real field experience. When will the change happen then you might ask. Very simple. If the largest destinations like fb/twitter and others start to drop v4. So what we really would need is not an ipv6 day, but, you might have guessed it, an ipv6 ONLY day. On such a day, a hell of a lot isps will have their support queue overfilled with people asking why they cannot visit their favourite sites. And all the isp can say is: our network infrastructure is too old. -------- Oorspronkelijk bericht -------- Van: Bob Evans <bob(a)FiberInternetCenter.com> Datum: Aan: Rafael Possamai <rafael(a)gav.ufsc.br> Cc: North American Network Operators' Group <nanog(a)nanog.org> Onderwerp: How long will it take to completely get rid of IPv4 or will it happen at all? Our fundamental issue is that an IPv4 address has no real value as networks still give them away, it's pennies in your pocket. Everything of use needs to have a cost to motivate for change. Establishing that now won't create change it will first create greater conservation. There will be a cost that will be reached before change takes place on a scale that matters. Networks set the false perception and customer expectation that address space is free and readily available. Networks with plenty, still land many customers today by handing over a class C to customer with less than 10 servers and 5 people in an office. We have a greater supply for packets to travel than we do for addresses required to move packets. Do you know how many packets a single IP address can generate or utilize, if it was attached too "The World's Fastest Internet" in someplace like Canadaland or Sweden on init7's Fiber7 ? No matter how large the pipe the answer is always, "all of it". It's address space we should now place a price upon. Unlike, My Space's disappearance when Facebook arrived there is no quick jump to IPv6. There is no coordinated effort required that involves millions of people to change browser window content. But to answer your question... Everything that is handed over for free is perceived as having no value. Therefore, IPv4 has to cost much more than the cost to change to IPv6 today. While the IPv6 addresses are free, it is expensive to change. Businesses spend lots of money on a free lunches. It's going to take at least the price of one good lunch per IP address per month to create the consideration for change. That's about $30 for 2 people in California. Offering a /48 of free IPv6 space to everyone on the planet didn't make it happen. There is no financial incentive to move to IPv6. In fact there is more reason "not to change" than "to change". The new gear cost $$$ (lots of it didn't work well and required exploration to learn that), IT people need hours to implement (schedules are full of day-to-day issues), networks keep growing with offerings that drop Internet costs and save everyone money, business as usual is productive on IPv4 (business doesn't have time for distraction), many of us get distracted by something more immediate and interesting than buying a new wi-fi router for the home. What will come first ? A) the earths future core rotation changes altering the ionosphere in such a way that we are all exposed to continuous x-rays that shorten our lifespan OR B) the last IPv4 computer running will be reconfigured to IPv6 Thank You Bob Evans CTO > Randy, > > How long do you think it will take to completely get rid of IPv4?

Trusted Networks Initiative: DDoS fallback set of AS'es
by David Hofstee 30 Jun '15

30 Jun '15

Hi, I saw the following and thought it would be interesting to share. In case of a persistent DDoS an ASy can fallback to a small set of (more trustable) AS'es for their routing: http://www.trustednetworksinitiative.nl/ They have a policy with procedural and technical parts, which may be upgraded later, for parties who want to participate: https://www.thehaguesecuritydelta.com/images/20141124_Trusted_Networks_Poli… Without having an opinion if everybody in the world should join this (I don't know the desired scope of this group), but the idea is interesting. I had not seen something like it before. Yours sincerely, David Hofstee Deliverability Management MailPlus B.V. Netherlands (ESP)

Any Verizon datacenter techs about?
by John Musbach 29 Jun '15

29 Jun '15

Hello, I'm a techie that recently moved to South Jersey for a tech job. To my astonishment, I discovered that there appears to be a Verizon datacenter near my house that has colocation: http://imgur.com/a/PdGno It's in Somers Point, NJ. While I could not find an address on the building, it is on the corner of Bethel Rd and N New Rd. I've tried walking around back to see if I could talk to anyone about colocation but could not find anyone outside. I've also tried calling Verizon but support wasn't very helpful. My question is, what does it take to get some colocation space inside of that building? Me and my roommate both have a 1u we'd like to rack and having it racked in a datacenter walking distance from where we live would be awesome. What we'd need: 2u space 4 power drops for the servers (2 psu per server) 2 100Mbps ethernet drops with static IPs I'm not sure if that's too little to ask for colocation or not, but that really is all we'd need. Is there anyone about that knows what we'd need to acquire such space, cost, badging, etc? If so, can you please reply offlist? Thanks, John M

Data Center Network Monitoring with TAPs
by Mitch Howards 29 Jun '15

29 Jun '15

Hello All, Was wondering what folks are using to monitor traffic on their networks. Looking into Ixia and APCON devices for dedup and other filtering features as well as passive fiber TAPs to capture the traffic. How are folks handling TAP'ing large data center networks? TAPs at the "distribution layer" would be the best fit for my network but that would require a ton of passive fiber TAPs for the incoming fibers to the distribution switches. The end goal is to not only capture the north-south traffic on the network but also east-west traffic. It seems more efficient to just use SPANs but there are many limitations using SPANs. Thanks in advance for any suggestions. Mitch
