USA local SIM card
by Max Tulyev 17 Sep '17

17 Sep '17

Hi All, sorry for possible off-topic, I really did not know where to ask this. I'm going to visit USA for two weeks. I want to buy a local prepaid SIM card mostly for IP access. Is it possible in USA to buy a prepaid SIM as a visitor, without long term contract? I need a public (can be dynamic) IP address, NOT over NAT, and (or) IPv6, if possible. My phone is GSM UMTS 3G. Expected traffic volume is about 10G. Will use it in New York City and Orlando City, not in rural areas. Good data roaming tariff in Cannada will be a big advantage. What can you advice? Thank you!

Reliability of looking glass sites / rviews
by Matthew Huff 17 Sep '17

17 Sep '17

This weekend our uninterruptible power supply became interruptible and we lost all circuits. While I was doing initial debugging of the problem while I waited on site power verification, I noticed that there was still paths being shown in rviews for the circuit that were down. This was over an hour after we went hard down and it took hours before we were back up. I worked with our providers last night to verify there weren't any hanging static routes, etc... We shut the upstream circuit down and watched the convergence and saw that eventually all the paths disappeared. Given what we saw on Saturday, what would cause route-views to cache the paths that long? Some looking glass sites only show what they are peered with or at most what their peers are peered with, that's why I've always used route-views. What looking glass sites other than route-views would people recommend?

You didn't mention details about which ASN or prefixes you were checking. Are you referring to ASN 14607 that only advertises two prefixes 129.77.0.0/16 and 2620:0:2810::/48? Based what we see over the weekend (using routeviews data), we see: Event Start Time: 2017-09-09 11:29:23 UTC (2017-09-09 07:29:23 EDT) Event End Time: 2017-09-09 13:31:30 UTC (2017-09-09 09:31:30 EDT) Are the above times correct? We see the routes withdraw and then come back. For example: http://demo-rv.snas.io:3000/dashboard/db/prefix-history?orgId=2&var-prefix=… When you checked routeviews, which router and peer were you looking at? When you did a "show ip bgp ..." did you include the prefix length? If not, it would have then shown you 0/0 or 128/5, depending on which router you were on. --Tim On 9/13/17, 8:43 AM, "NANOG on behalf of Matthew Huff" <nanog-bounces(a)nanog.org on behalf of mhuff(a)ox.com> wrote: Both should have been similar.

Can you help on a survey on network testing?
by Yifei Yuan 15 Sep '17

15 Sep '17

Dear Folks, My name is Yifei Yuan, and I am a researcher at Carnegie Mellon University. I am working on a research project related to testing network configurations, where I want to survey the problems that are encountered when conducting testing on networks. I would very much appreciate it, if you could participate this survey, which can be found in the following link: http://cmu.ca1.qualtrics.com/jfe/form/SV_bvE1oBeO9NI5r5X The survey is anonymous, and it would take no more than 5 mins to finish up all questions. Your participation is voluntary with no compensation, and you must be at least 18 years of age to complete the survey. Thanks, Yifei Yuan Postdoctoral researcher ECE, CMU

Operational message: DNS root zone KSK rollover to occur on October 11, 2017 at 1600 UTC
by Matt Larson 15 Sep '17

15 Sep '17

The root zone management partners, ICANN and Verisign, are working together to change the DNS root zone's key-signing key (KSK). This process is referred to as "rolling" the root zone KSK. The root zone's apex DNSKEY RRset has been signed with the same KSK, known as KSK-2010, since the root zone was first signed in July, 2010. On October 11, 2017, at approximately 1600 UTC, the root zone will be published with the apex DNSKEY RRset signed for the first time with a new KSK, known as KSK-2017. The root zone apex DNSKEY RRset will be signed with only KSK-2017 going forward. While the specific date of the KSK rollover, October 11, 2017, had been announced previously, the time of 1600 UTC on that day has not been announced until now, which is the primary purpose of this message. The public portion of the root zone KSK is configured as a trust anchor in software performing DNSSEC validation. The configuration of any software performing DNSSEC validation will need to be updated to reference KSK-2017 on or before October 11, 2017, or all DNS responses received by that software will fail DNSSEC validation, resulting ultimately in error messages to end users. In many cases, software performing DNSSEC validation supports "Automated Updates of DNS Security", the protocol defined in RFC 5011 that can automatically update a DNSSEC validator's trust anchor configuration. If the software does not support this protocol, or it is incorrectly implemented or not configured correctly, the trust anchor will need to be updated manually. Anyone operating software performing DNSSEC validation with the root zone KSK configured as a trust anchor must take action on or before October 11, 2017, to confirm that their software is configured with KSK-2017 as a trust anchor and, if not, take the necessary steps to update the configuration. Further information about the root KSK rollover, including information about how to check and update the trust anchor configuration of popular recursive resolver implementations that support DNSSEC validation, is available at https://icann.org/kskroll. For the root zone management partners, Matt Larson VP of Research, ICANN Duane Wessels Distinguished Engineer, Verisign

Find carriers that peer in two IX's
by Dovid Bender 15 Sep '17

15 Sep '17

Hi, Does anyone know of a tool like PeeringDB where I can select two exchanges say TELX 60 Hudson and then SIX (Seattle IX) and find all carriers that have a presence in both locations? TIA. Dovid

You were offering advice to someone without investigating the characteristics of his network. That advice could well have negative tradeoffs which you neglected to mention. I felt a duty to point them out. Owen
