About Akamai

The AS number under which Akamai’s European entity announces most of the Akamai edge platform. Akamai places servers inside many other networks too, so Akamai-delivered sites also appear under other AS numbers.

What it means when a site’s IP address is in this network

Akamai is an edge network: the address you see belongs to a proxy that answers on behalf of the site. The origin server sits somewhere else and is not visible from outside, so the address says nothing about where the site is really hosted, in which country, or with which hosting company. Many unrelated sites share the same addresses. The TLS certificate and some response headers may also come from the edge.

Check which network a domain is in

The IP lookup resolves a domain, then shows the AS number, prefix and network name of each address. Addresses in AS20940 link back to this page.

FAQ

Who owns AS20940?

AS20940 is registered to Akamai. The live box on this page shows the name, registry and allocation date as the registry data gives them at the moment of the lookup.

A website’s IP address is in AS20940. Is the site hosted by Akamai?

Not necessarily. Akamai is an edge network, so the address belongs to a proxy in front of the site. The origin server can be with any hosting company and is not visible from outside.

How do I find the AS number of a domain?

Resolve the domain to its A and AAAA records and look up each address. OrbitProbe’s IP lookup does both and shows the AS number, the announced prefix and the network name for every address.

Does the country of an AS number show where the server is?

No. It is the country in which the number is registered. Networks announce addresses from many locations, and anycast networks answer from whichever site is closest to the visitor.
