Re: Internet services in Antarctica

It would be really hard to quantify antarctic IPs as actually being from there. I know some of the people who've operated the geostationary links to McMurdo and to the pole (inclined orbit satellite visible only part of the day). Their WAN links go through geostationary transponder capacity and

Looking for topology mapping validation

Hi NANOG, 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

Re: DDoS Mitigation Survey

Exactly, so one of the best option to fight DDoS is not available through public information. @Lumin: You should start your investigation with uRPF loose. Best regards, Jean On 2020-01-20 11:31, Dobbins, Roland wrote: On 20 Jan 2020, at 22:49, Jean | ddostest.me wrote: uRPF loose or

Re: Internet services in Antarctica

from 1995-1996, i placed a DNS root server in Antarctica. Funding for the bandwidth cost was high enough that I pulled the service. Never really delved into the actual requirement for "real-time" interactions that could not be localized. caching and batch transfers cover most of the need. for

Re: DDoS Mitigation Survey

uRPF loose or strict. Which ISP supports it? So far, I found none through public information. On 2020-01-20 10:38, Dobbins, Roland wrote: On 20 Jan 2020, at 19:59, Jean | ddostest.me via NANOG wrote: Where can we find public information on how to use S/RTBH This .pdf preso on mitigation

Where can we find public information on how to use S/RTBH and which providers support it. Thanks Jean On 2020-01-14 17:31, Dobbins, Roland wrote: There are literally decades of information on these topics available publicly. Router and switch ACLs (both static and dynamically-updated via

Internet services in Antarctica

Hi, I have a hobby project running DNS service to people looking for NTP public servers. I noticed that the DNS servers apparently get ~5 thousand queries per day from IPs that the GeoIP database we use claim are in in Antarctica. It’s less than 0.0001% of the overall DNS queries, but it made
