Anurag Bhatia
And here goes first blog post of 2018. Last few months went busy with some major changes in personal life. :) I looked into Amazon’s India connectivity with various ASNs tonight. Here’s how it looks like. (Note: Jump to bottom most to skip traces and look at the summary data). Traceroutes Amazon India to Vodafone India traceroute to 118.185.107.1 (118.185.107.1), 30 hops max, 60 byte packets 1 ec2-52-66-0-128.ap-south-1.compute.amazonaws.com (52.66.0.128) 21.861 ms ec2-52-66-0-134.

Cloudflare hosting F root server

A few days some folks in internet community noticed Cloudflare AS13335 announcing F root server’s routes covering prefix 192.5.5.0/24. dig version.bind ch txt @f.root-servers.net pic.twitter.com/YLW7hqt170 — Tony Finch (@fanf) April 3, 2017 Above tweet shows that case is clearly not a mistake but rather some sort of arrangement between Cloudflare and ISC (which is responsible for F-root). There was another discussion on DNS-OARC mailing list here. From our bgp.he.net tool, one can analyse route propagation for F root’s AS3557.
