Summary:
- This article discusses a technology called Carrier Grade Network Address Translation (CGN), which is used by internet service providers to share IP addresses among multiple customers.
- The article explains how Cloudflare, a web infrastructure and website security company, has developed a method to detect the use of CGN in order to improve the performance and reliability of their services.
- By detecting CGN, Cloudflare can better understand the network conditions of their customers and take appropriate measures to reduce the potential "collateral damage" that can occur when multiple users share the same IP address.
