About Akamai
Akamai is one of the oldest and largest content delivery networks, serving media, software downloads and web applications from servers embedded in thousands of networks worldwide. Many Akamai servers sit inside other operators' networks, so Akamai content can be served from address space that is not registered to Akamai.
What traffic from Akamai addresses usually means
Addresses in Akamai's own ranges are typically CDN edge servers delivering content or proxying requests to origins. They are shared by many customers, so blocking one can break unrelated sites and downloads.

Frequently asked questions
How many IP addresses does Akamai have?
Akamai uses 3,953 IPv4 address blocks. After merging overlapping ranges, the IPv4 blocks cover about 13.9 million unique addresses. Counts change as the provider adds, retires or transfers address space.
How can I check if an IP address belongs to Akamai?
Enter the address in the IPDebrief IP lookup. If it falls inside one of Akamai's ranges, the profile names the provider alongside the announcing network, location and risk signals.
Which ASN does Akamai use?
Akamai announces its address space from AS20940 and AS16625. An autonomous system number identifies the network that routes the addresses on the internet; each ASN page lists the analysed addresses observed in that network.
Is traffic from Akamai IP addresses safe?
Addresses in Akamai's own ranges are typically CDN edge servers delivering content or proxying requests to origins. They are shared by many customers, so blocking one can break unrelated sites and downloads. Of the 6,224 Akamai addresses IPDebrief has analysed, 314 (5%) currently score as higher risk, so judge each address on its own profile.
Where does this IP range data come from?
Ranges are compiled from address lists the operator publishes and from global routing data, refreshed regularly. Address-level risk comes from independent observations of each address, recomputed in the background.
