About this network

One of Akamai's Autonomous Systems (AKAMAI). Akamai runs one of the oldest and most widely distributed content-delivery networks, with edge servers embedded deep inside thousands of networks.

What it's used for

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

Notable

• Akamai's model is extreme distribution, so an Akamai IP is usually very close to the requester. Akamai runs many ASNs — see AS20940.

Interesting

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