About

What is Akamai?

Akamai has run a content delivery network since 1998, with servers inside thousands of ISP networks. Enterprises use it for delivery, DDoS protection and bot management.

Akamai announces its addresses from many autonomous systems, and some of its servers sit inside other networks. Its hostnames, such as edgekey.net and akamaiedge.net, are the most reliable sign of a site behind Akamai.
