Best way to get foreign ISPs to shut down DDoS reflectors?
by Bottiger 24 Apr '20

24 Apr '20

Is there a guide on how to get foreign ISPs to shut down reflectors used in DDoS attacks? I've tried sending emails listed under abuse contacts for their regional registries. Either there is none listed, the email is full, email does not exist, or they do not reply. Same results when sending to whatever other email they have listed. Example Networks: CLARO S.A. Telefonica China Telecom Korea Telecom

by Vincent Celindro 24 Apr '20

24 Apr '20

Share your insights at NANOG 79 With a remote presentation that brings your research + ideas to life. Due to the COVID-19 global pandemic, NANOG 79 will now be held as a virtual meeting <https://nanog.org/meetings/nanog-79/> with an abridged program (June 1-3). The in-person meeting in Boston has been canceled to ensure the health and safety of our community. The NANOG Program Committee (PC) is developing a program tailored to the three-day meeting with an online format, and has extended the Call For Presentations to May 7. We encourage anyone interested in sharing their research, ideas, and best practices with the greater NANOG community to submit a proposal for a talk, tutorial, or panel to be presented virtually. Submit Now <https://nanog.org/participate/call-presentations/> View Guidelines <https://www.nanog.org/participate/presentation-guidelines/> In addition to proposals focused on current (or soon-to-be deployed) technologies and industry innovation, we believe our community would also be interested in the following topics: - Impact to Networks & Engineers as a result of COVID-19 - Insights on working from home, VPN, sustained traffic, shifting of resources, application changes, etc. - Online conferencing security, BYOD and desktop security, family and work. - RPKI Deployments - Professional Development - Advice on white boarding, public speaking, negotiating, etc. We look forward to reading your proposals, and connecting online this June! Sincerely, Vincent Celindro NANOG - Program Committee Chair on behalf of the NANOG PC

FlowSpec
by Colton Conor 24 Apr '20

24 Apr '20

Do any of the large transit providers support FlowSpec to transit customers / other carriers, or is that not a thing since they want to sell DDoS protection services? FlowSpec sounds much better than RTBH (remotely triggered blackhole), but I am not sure if FlowSpec is widely implemented. I see the large router manufacturers support it.

Well, ARIN's, too. I get what you're saying for the internet in general. It seems NANOG could see javascript being blocked and redirect folks to a non-insecure (javascript) site like others (twitter, for example) do. Then, I could use Lynx! (kidding!) :) scott

Comcast - Significant v4 vs v6 throughput differences, almost stateful.
by Nick Zurku 23 Apr '20

23 Apr '20

Hello all, I would appreciate if someone from Comcast could contact me about this. We’re having serious throughput issues with our AS20326 pushing packets to Comcast over v4. Our transfers are either the full line-speed of the Comcast customer modem, or they’re seemingly capped at 200-300KB/s. This behavior appears to be almost stateful, as if the speed is decided when the connection starts. As long as it starts fast it will remain fast for the length of the transfer and slow if it starts slow. Traces seem reasonable and currently we’ve influenced the path onto GTT both ways. If we prepend and reroute on our side, the same exact issue with happen on another transit provider. This issue does not affect v6 and that is full speed on every attempt. This may be regionalized to the Comcast Pittsburgh market. This is most widely affecting our linux mirror repository server: http://mirror.pit.teraswitch.com/ Our colocation customers who are hosting VPN systems are also noticing bottlenecks have started recently for their Comcast employees. -- Nick Zurku Systems Engineer TeraSwitch, Inc. nzurku(a)teraswitch.com

xplornet contact or any experience with their satellite service?
by Brian J. Murrell 23 Apr '20

23 Apr '20

A friend of mine just recently got Xplornet satellite service at his rural home. I'm well aware of the latency issues with satellite although frankly his latency is much better than I had feared it would be and is around 600-700ms. But what seems to be worse than the latency is the "burstiness" of the traffic and I am just wondering if that is normal/expected for satellite service in general, and/or expected from Xplornet's service, or if what I am seeing is not expected at all (i.e. not an artifact of the satellite signal but rather a network management issue).

As you can imagine, the bursiness of this makes for horrible video conferencing since that cannot "buffer" the way single-direction streams like streaming video can and the codec ends up using the "worst case" dips as the speed of the connection and encodes for that.

Venmo - Geolocation Challenges
by Justin Krejci 23 Apr '20

23 Apr '20

Hello, I am looking for a Venmo network contact that can assist with a geolocation error in their systems. We have customers on a particular IP prefix who are being flagged by Venmo as outside of the USA but they are not outside of the USA. All standard geolocation systems I can find, as well as ARIN, all show the IP prefix as within the USA. Normal Venmo support channels are not fruitful to resolve the issue, they mostly just indicated users need to use their mobile data connection to get a different IP address for Venmo transactions. That is fine as a temporary work around but that is not a solution. Venmo support has expressed they are not going to do anything more for us in this regard. So if anyone has a relevant contact I might reach out to at Venmo or knows if Venmo uses a particular 3rd party geolocation data set and can share that with me that would be appreciated. I don't mind working with any organization to straighten out any stale data, I just need some assistance getting to someone who has the info or access. Thanks!! Justin Krejci

"Is BGP safe yet?" test
by Andrey Kostin 23 Apr '20

Hi Nanog list, Would be interesting to hear your opinion on this: https://isbgpsafeyet.com/ We have cases when residential customers ask support "why is your service isn't safe?" pointing to that article. It's difficult to answer correctly considering that the asking person usually doesn't know what BGP is and what it's used for, save for understanding it's function, design and possible misuses. IMO, on one hand it promotes and is aimed to push RPKI deployment, on the other hand is this a proper way for it? How ethical is to claim other market players unsafe, considering that scope of possible impact of not implementing it has completely different scale for a small stub network and big transit provider? Kind regards, Andrey
