APNIC Hackathon at APRICOT 2018

APNIC and RIPE NCC are doing a hackathon at APRICOT 2018. It just started today with some light interaction with various participating members yesterday.


The theme of the hackathon is around IPv6. Many cool projects were suggested yesterday and teams started working today on certain shortlisted projects like:

  1. A tool for ranking CDNs – A tool based on RIPE Atlas data to rank CDNs based on latency across different regions.
  2. An IPv6 fun word game – Where anyone with a member account can suggest a word, and compete with other members who share more IPv6 addresses. It may include things like showcasing creative use of hexadecimal strings in an IPv6 address like Facebook popularly does face:b00c in their IPv6 pools.
  3. IPv4 and IPv6 network security  – Study of attacks and overall security in IPv6. It would involve study and possibly a report on various attack vectors in the IPv6 domain.
  4. A countrywide report on IPv6 deployment – I have yet to see how it is different from existing other reports.
  5. IPv6 tunnel detection – Figuring out where tunnels used and figuring out the IPv4 address of those endpoints via a javascript plugin and possibly comparing IPv4 Vs IPv6 performance.

Let’s see how things go in next 12hrs. Super fun. Things should show up on Github in next few hours. 🙂

Disclaimer and misc points:

  1. It’s a hackathon and final thing may vary greatly from the original idea. Let’s see how things evolve.
  2. The final tool which uses such idea/code may be awesome but for next 12hrs it will be more around proof of concept and small demo instead of a full-fledged tool in certain cases.
  3. I am part of the jury for the hackathon.

RIPE Atlas India coverage and some thoughts

It has been some time since I started pushing Indian community for hosting RIPE Atlas Probes. These probes are small devices designed to be hosted at end user’s connection and do pre-defined as well as user-defined measurement. Measurement includes ping, trace, DNS lookup, SSL check etc.

Currently, there are 61 active RIPE Atlas probes. I would say it has +/- of 7-8 probes which go offline and come back online when I request hosts to check.



Map of probes in India


I think now we about to reach a scenario where we should focus more around probes in specific regions and specific networks. Metro cities have some probes but outside are pretty much missing. Plus almost no probe in central India. In terms of ASN coverage, we can look at Hurricane Electric’s country report for top ASNs list – https://bgp.he.net/country/IN


Following top ASNs IP network are missing from coverage of probe network:

  1. Reliance Communications  – AS18101
  2. Vodafone India – AS55410
  3. Sify – AS9583 (I recently shipped probes to them and expecting few to go online soon)
  4. TTSL – AS45820
  5. IDEA Cellular – AS55644
  6. Aircel – AS10201
  7. Syscon Infoway – AS45194
  8. CtrlS datacenter – AS18229
  9. Ishan’s Network – AS45117
  10. Railtel Corp – AS24186


In case you work for any of these networks or are a customer of these networks, please consider hosting RIPE Atlas probe. You can fill the form given below and I will send you a probe on priority.
