raw bgp traffic
by Javier Godinez 22 Feb '11

Deal NANOG, Does anyone know where I can get real/raw BGP traffic, maybe in pcap format? I just need maybe a few days of raw data for an inline analysis tool I am developing. Thank you, Javier

Hi Oleg, You are correct. We got our default values mixed up. We will correct this on the blog post.

Graph Utils (Open-Source)
by Max Pierson 21 Feb '11

21 Feb '11

Hi List, Anyone out there using something other than rrdtool for creating graphs?? I have a project that will need a trend taken, and unfortunately rrdtool doesn't fit the bill. All of the scripting, data collection, database archival, etc will be custom written or is already done (with some hacks of course :). So really what i'm looking for is something along the lines of GNUplot. Has anyone used it before and would like to share experiences?? Seems like it will be able to my plot data accordingly, but wanted to see if there were any other popular tools I've yet to come across. (Open-Source only please) TIA, M

Traffic to 5/8 and 37/8 - stats on RIPE Labs
by Mirjam Kuehne 21 Feb '11

21 Feb '11

Hello, During NANOG 51, Manish Karir gave a Lightning Talk showing how much and what kind of traffic is going to unallocated address space in 5/8 and 37/8 (among other ranges he tested). This is now also available on RIPE Labs: http://labs.ripe.net/Members/mkarir/first-impressions-of-pollution-in-two-r… Kind Regards, Mirjam Kuehne RIPE NCC

IPv6 consumer perception
by Zed Usser 21 Feb '11

21 Feb '11

With marketing campaigns like these, no consumer will want to use IPv6, if it becomes associated with privacy problems. http://torrentfreak.com/huge-security-flaw-makes-vpns-useless-for-bittorren… It is, of course, totally irrelevant whether the reporting is factually correct or even based on real IPv6 issues or not, this is how public opinion is formed. The only takeaway from this to a non-technical user is that IPv6 is bad and the correct solution is to turn it off. - Zed

You've misunderstood the granularity of my question, though, Jim. :-) I asked not what the default behavior was, but *whether it was even manually possible to override* that default behavior. I believe it is not, which would serve as much stronger evidence for your case. > You will of course need to use a decent lookup tool like dig to do > this.

When you say, though, that this permitted child zones to have no NS records in them, I presume you mean "when the same server is serving both the parent and the child in question"? Cheers, -- jra

VZW LTE provisioning
by Jay Ashworth 20 Feb '11

20 Feb '11

Is there anyone on the list who can comment, on- or off-list, for-attribution or not, on what kind of job Verizon Wireless has done provisioning the data backbone for their new LTE "4G"[1] rollout? Given the fact that it is at 700MHz and will therefore have *substantially* better building penetration, and the fact that -- due to the Google imposed "any device, any app" restrictions the FCC placed on their license -- there is quite a bit higher possibility that we'll see better device competition on this service than we've seen before... the odds that we'll have to deal with it, as operators of larger end-networks, seem pretty high. Knowing what we're getting into would be nice. :-) Cheers, -- jra [1] The ITU has said that none of {HSDPA,LTE,WiMax} qualifies for "4G" designation by the standards, of which they (I understand) are the promulgating agency.
