About this network

A core Akamai Autonomous System (AKAMAI). Akamai runs one of the oldest and most widely distributed CDNs, with edge servers embedded deep inside thousands of networks worldwide.

What it's used for

• Caching and accelerating content, plus DDoS/WAF security, for large enterprises, media, banks, and software vendors.

Notable

• An Akamai IP is an edge server, not the customer origin behind it.
• Akamai uses many ASNs (e.g. AS20940 Akamai International); which one announces a given prefix varies by network and history.

Interesting

• Akamai grew out of late-1990s MIT research on serving content during massive traffic spikes ("flash crowds").
