Comcast Support (from NANOG Digest, Vol 84, Issue 23)
by Brzozowski, John 25 Feb '15

25 Feb '15

Folks, The thread below was sent to me a few times, apologies for not catching it sooner. Janet, I sent you mail unicast with a request for some information. I am happy to help you out. For the larger NANOG audience, Comcast has recently launched IPv6 support for our BCI products, these are our DOCSIS based commercial offerings. This means that if you gateway device is in fact in RG mode you will be delegated a dynamic IPv6 prefix, by default customers are delegated a /56 prefix along with a single IPv6 address that is assigned to the WAN of the gateway device. IPv6 support applies to the following makes and models: SMC D3G CCR (http://mydeviceinfo.comcast.net/device.php?devid=216) Cisco BWG (http://mydeviceinfo.comcast.net/device.php?devid=347) Netgear CG3000D (http://mydeviceinfo.comcast.net/device.php?devid=347) For customers where you bring your own cable modem or have one of the above in bridge mode we have enabled IPv6 support for you as well. However, your router behind the modem must be running software and configured with IPv6 support. Specifically, your router needs to be support stateful DHCPv6 for IPv6 address and prefix acquisition. We have received a number of reports from customers that the Juniper SRX does not appear to properly support IPv6. We are working with Juniper and also recommend that you reach out to Juniper as well. Please keep checking http://www.comcast6.net for updates, we will post some additional information here in the next week or so. In the mean time if you have questions feel free to send me mail or post them here on the NANOG list.

I'm not getting an IPv6 address on the Comcast provided cable modem/router. I'm not getting a PD. My machines thus have no IPv6. I've hard reset my router 4 times while working with Comcast, and I've been told to do things like switch to a static IPv4 address, which shows a level of clue that is scary. And before that they were convinced it was a wireless problem even though I have a wired connection, and told them that multiple times. I've wasted two hours with Comcast today, and even when I asked for escalation I got nothing. Just hung up on. It's honestly the worst customer support I've ever received. I don't think I ever got them to understand the difference between IPv4 and IPv6.

Call For Presentations RIPE 70, submission deadline 1 March 2015
by Benno Overeinder 19 Feb '15

19 Feb '15

Dear colleagues, Please find the CFP for RIPE 70 below. The deadline for submissions is 1 March 2015. Please also note that speakers do not receive any extra reduction or funding towards the meeting fee at the RIPE Meetings. Kind regards, Benno Overeinder for the RIPE Programme Committee http://www.ripe.net/ripe/meetings/ripe-meetings/pc ---------------------------------------- Call for Presentations A RIPE Meeting is an open event where Internet Service Providers, network operators and other interested parties get together. Although the meeting is mostly technical, it is also a chance for people to meet and network with others in their field. RIPE 70 will take place from 11-15 May 2015 in Amsterdam, The Netherlands. The RIPE Programme Committee (PC) is now seeking content proposals from the RIPE community for the plenary session presentations, BoFs (Birds of a Feather sessions), panels, workshops, tutorials and lightning talks at RIPE 70. The PC is looking for presentations covering topics of network engineering and operations, including but not limited to: - IPv6 deployment - Managing IPv4 scarcity in operations - Commercial transactions of IPv4 addresses - Data centre technologies - Network and DNS operations - Internet governance and regulatory practices - Network and routing security - Content delivery - Internet peering and mobile data exchange Submissions RIPE Meeting attendees are quite sensitive to keeping presentations non-commercial, and product marketing talks are strongly discouraged. Repeated audience feedback shows that the most successful talks focus on operational experience, research results, or case studies. For example, presenters wishing to describe a commercial solution should focus on the underlying technology and not attempt a product demonstration. The RIPE PC accepts proposals for different presentation formats, including plenary session presentations, tutorials, workshops, BoFs (Birds of a Feather sessions) and lightning talks. See the full descriptions of these formats at https://ripe70.ripe.net/submit-topic/presentation-formats/ Presenters who are proposing a panel or BoF are encouraged to include speakers from several (perhaps even competing) companies and/or a neutral facilitator. In addition to presentations selected in advance for the plenary, the RIPE PC also offers several time slots for "lightning talks", which are selected immediately before or during the conference. The following general requirements apply: - Proposals for plenary session presentations, BoFs, panels, workshops and tutorials must be submitted for full consideration no later than 1 March 2015, using the meeting submission system at https://ripe70.ripe.net/submit-topic/submission-form/. Proposals submitted after this date will be considered on a space-available basis. Important Dates regarding RIPE 70 can be found at: https://ripe70.ripe.net/programme/important-dates/ - Lightning talks should also be submitted using the meeting submission system (https://ripe70.ripe.net/submit-topic/submission-form/) and can be submitted just days before the RIPE Meeting starts or even during the meeting week. The allocation of lightning talk slots will be announced in short notice – in some cases on the same day but often one day prior to the relevant session. - Presenters should indicate how much time they will require. See more information on time slot allocations per presentation format at https://ripe70.ripe.net/submit-topic/presentation-formats/. - Proposals for talks will only be considered by the PC if they contain at least draft presentation slides (slides may be updated later on). For panels, proposals must contain a clear description, as well as the names of invited panellists, presenters and moderators. - Due to potential technical issues, it is expected that most, if not all, presenters/panellists will be physically present at the RIPE Meeting. If you have any questions or requests concerning content submissions, please email pc [at] ripe [dot] net. -- Benno J. Overeinder NLnet Labs http://www.nlnetlabs.nl/

IPv6 allocation plan, security, and 6-to-4 conversion
by Eric Louie 10 Feb '15

10 Feb '15

I'm putting together my first IPv6 allocation plan. The general layout: /48 for customers universally and uniformly /38 for larger regions on an even (/37) boundary /39 for smaller regions on an even (/38) boundary A few /48's for "internal use" to allow us to monitor and maintain systems. For security sake, do I need (am I better off) to "reserve" a "management block" (/39, /40, /41 or something of that nature) that does NOT get advertised into BGP to my upstreams, and use that for my device management and monitoring address space? In other words, make a small "private" address space for management? What are folks doing around that? If I have to do 6-to-4 conversion, is there any way to do that with multiple diverse ISP connections, or am I "restricted" to using one entry/exit point? (If that's true, do I need to allocate a separate block of addresses that would be designated "6 to 4" so they'd always be routed out that one entry/exit point?)

[request]: host a probe for v6 measurements
by Bajpai, Vaibhav 09 Feb '15

09 Feb '15

Dear NANOG, We are currently looking for volunteers in US with native IPv6 lines to help us in our v6 measurement research. <——------ Background We are interested in measuring IPv6 performance from home. As part of the LEONE project [1], we have developed measurement tests that compare performance over IPv4 and IPv6 to: a) Dual-stacked websites and b) YouTube content delivery network (in collaboration with Aalto University). The tests comes bundled with a LEONE SamKnows probe. [1] http://www.leone-project.eu We currently have ~25 Vantage points (VP). Each VP runs a Leone SamKnows probe. The google map [2] shows where these probes are deployed. As you can see the VP sample is too small (nothing in North America) [2] http://goo.gl/TL4woP <——------ Request: If you receive native IPv6 at home (or know someone who does), it would be great if you can host a LEONE SamKnows probe for us. The probe will run standard SamKnows tests [3] and our IPv6 tests. [3] https://www.samknows.com/tests-and-metrics We prefer measuring from home networks, but are also open to deploying probes within research/academic networks, business lines, or operators labs. <-------- Action: Let me know if you’re interested, and I can share details on how to get the probe to you. We only have limited number of LEONE SamKnows probes. We will process the requests on first come first serve basis. <-------- Research Impact. a) Measuring YouTube from Dual-Stacked Hosts Saba Ahsan, Vaibhav Bajpai, Jörg Ott, Jürgen Schönwälder Passive and Active Measurement Conference (PAM 2015), New York, March 2015. b) Measuring TCP Connection Establishment Times of Dual-Stacked Web Services Vaibhav Bajpai, Jürgen Schönwälder 9th International Conference on Network and Service Management, (CNSM 2013) Zürich, October 2013. 8<——-- Thanks. Thank you so much for helping us in our research activity.

scaling linux-based router hardware recommendations
by micah anderson 07 Feb '15

07 Feb '15

Hi, I know that specially programmed ASICs on dedicated hardware like Cisco, Juniper, etc. are going to always outperform a general purpose server running gnu/linux, *bsd... but I find the idea of trying to use proprietary, NSA-backdoored devices difficult to accept, especially when I don't have the budget for it. I've noticed that even with a relatively modern system (supermicro with a 4 core 1265LV2 CPU, with a 9MB cache, Intel E1G44HTBLK Server adapters, and 16gig of ram, you still tend to get high percentage of time working on softirqs on all the CPUs when pps reaches somewhere around 60-70k, and the traffic approaching 600-900mbit/sec (during a DDoS, such hardware cannot typically cope). It seems like finding hardware more optimized for very high packet per second counts would be a good thing to do. I just have no idea what is out there that could meet these goals. I'm unsure if faster CPUs, or more CPUs is really the problem, or networking cards, or just plain old fashioned tuning. Any ideas or suggestions would be welcome! micah

Recommended wireless AP for 400 users office
by Manuel Marín 04 Feb '15

04 Feb '15

Dear nanog community I was wondering if you can recommend or share your experience with APs that you can use in locations that have 300-500 users. I friend recommended me Ruckus Wireless, it would be great if you can share your experience with Ruckus or with a similar vendor. My experience with ubiquity for this type of requirement was not that good. Thank you and have a great day

Indiana Dark Fiber
by Mike Hammett 31 Jan '15

31 Jan '15

Any recommendations for dark fiber between Indianapolis and Fort Wayne? I see a few routes, but that doesn't mean they actually sell dark fiber. The company that we've partnered with asked a couple companies (Zayo, IFN and one of the Time Warners) and came up short. Seems odd because Zayo lists dark fiber routes to within 1.5 miles of the Fort Wayne location, but figured I'd look to see what companies I was missing that actually did dark fiber. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com

HOW did they make it--seems like it would have been like making a hole in a bass drum with a finger (lot of bounce, not much cut)? How long did it take to put that many in, and how many worked on the project? Why didn't some alarm or path measurement disclose the deterioration before the cavity was packed so full?
