Description

EDNS Client Subnet when finally published in 2016 (rfc7871), attempted to solve a need for some content delivery networks to know where queries originated. When published, the RFC clearly outlines privacy concerns, but how does that look in practice?

More than 20+ million Internet properties use Cloudflare's network and approximately 18% of the top 10k websites on the internet use at least one Cloudflare product. In terms of DNS queries, we consistently do approximately 2 million DNS queries per second. That's around 170 billion queries per day, and 5 trillion queries a month. In this talk, we’ll dive into the ECS landscape from Cloudflare’s perspective… where is ECS data coming from, who is sending it, and what does it contain?

Talk Duration Lightning Talk 10 Minutes
