Looking for topology validation
by Kévin Vermeulen 24 Jan '20

24 Jan '20

Hi NANOG, Sorry for multiple sendings. First of all, thanks to the operators that have contributed to our survey, we will acknowledge you publicly. I just resend the message one last time, hoping to get some more feedback. Our teams at Sorbonne Université and Naval Postgraduate School have developed a new Internet topology mapping tool, Diamond-Miner. Diamond-Miner[3] combines Paris Traceroute Multipath Detection Algorithm[1] and high probing rate Yarrp[2] techniques to trace the load balanced paths at Internet Scale. We are seeking now some validation of our inferences, in particular the traceroutes links that we have found. We have developed a small website for operators to provide validation: http://heartbeat.planet-lab.eu:8000 You can either publicly submit the validation on the website or send us an email to kevin.vermeulen(a)sorbonne-universite.fr . You will find all the details on the website, do not hesitate to ask if you have further questions. Thanks in advance, Kevin [1]: https://arxiv.org/pdf/1809.10070 [2]: http://rbeverly.net/research/papers/yarrp-imc16.pdf [3]: https://www.usenix.org/conference/nsdi20/accepted-papers

digitalelement.com GeoIP?
by Justin Wilson 24 Jan '20

24 Jan '20

Has anyone have a contact with digitalelement.com <http://digitalelement.com/> and their GeoIP stuff? We received a new ipv4 block from ARIN last week and HULU tells digitalelement.com <http://digitalelement.com/> is who they use. Our new block is not being coded correctly. I can not find any sort of technical contact on the Digital Element web-site. It’s all marketing stuff. Any help would be appreciated.

Prefixes blocked by Verisign, can’t reach Root DNS Server?
by Nandipati, Naveen 23 Jan '20

23 Jan '20

Hi Kushal, As discussed privately this was resolved by forwarding traffic through an alternate upstream carrier. The issue arose due to lack of return path from Verisign to your network through the common peer and can also be resolved by announcing all your internal prefixes to our common peering partner. Feel free to reach out for any further support from Verisign. ---------- Thanks Naveen

Spectrum technical contact
by Josh Luthman 23 Jan '20

23 Jan '20

We have had a DOS attack for over 12 hours. I simply want them to null route or black hole an address. The traffic is filling one of our circus with them. The farthest I got was them telling me they can't do route changes because we're not public safety. Josh Luthman Office: 937-552-2340 Direct: 937-552-2343 1100 Wayne St Suite 1337 Troy, OH 45373

Provider Suggestions for Diverse 10g Wave CHI-NJ
by Josh Niec 23 Jan '20

23 Jan '20

Hey Nanog, Could anyone suggest providers for a diverse/alternative 10g wave service between Equinix in Chicago and Equinix in New Jersey (northeastern part of the state)? Currently we have a 10g wave service via the infamous Spread Networks low-latency path between the two locations, but are looking for a second that is completely diverse with no overlaps between the two data centers. Our current provider is Crown Castle Fiber, and half of the segment, from the Ohio area to New Jersey, is leased from Zayo (who purchased Spread) by CCF. I want diverse carriers for this other path, so Zayo/CCF are not an option. I’ve checked with CenturyLink/Level3 who are unable to provide a completely diverse path. I have also reached out to Verizon who have been dragging me through a 3 month+ long process with no proposals so far (they wanted me to sign the contract before showing me the actual route of the circuit, with no guarantee that it wouldn’t overlap).

A survey on performance diagnosis for Network functions/middleboxes
by Yu, Minlan 22 Jan '20

22 Jan '20

Dear Nanog community, Today's networks (data centers, ISPs, and enterprises) all run many hardware middleboxes and software network functions. The performance of these components is critical for network management and user experiences. However, when performance problems happen, it often takes a lot of human efforts to instrument and debug these systems especially when many network functions interact with each other and with traffic dynamics. We are a group of researchers from Harvard and AT&T who are building new diagnosis tools that can automatically find potential root causes for performance problems in network functions (especially those tail latency problems that are hard to diagnose). We're reaching out to the NANOG community to understand the performance problems you have seen and your needs on diagnosis tools. This will greatly help us to incorporate your needs in our tool. We plan to release our debugging tool for the community to use. We greatly appreciate your help in filling out the survey below. It should take less than 10 minutes to complete. The survey and the collected data are anonymous (so please do *not* include information that may identify you or your organization). All questions are optional, so if you don't like a question or don't know the answer, please skip it. In the survey, we use network functions as a general term to represent both hardware and software middleboxes. A summary of the aggregate results will be published as a part of a scientific article later this year. Survey URL: https://docs.google.com/forms/d/e/1FAIpQLSdx1j2BZzk_iEuIqHLDF20Rv_LuxLcrGze… We would also be extremely grateful if you could forward this email to any operator you know beyond this NANOG mailing list.
