AS63949: the AKAMAI-LINODE-AP Akamai Connected Cloud network

AS63949 is an internet Autonomous System operated by AKAMAI-LINODE-AP Akamai Connected Cloud (Singapore). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS63949?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS63949 was assigned to AKAMAI-LINODE-AP Akamai Connected Cloud by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS63949 currently announces 79 IPv4 block(s), totaling about 1.4 million addresses (1,350,144 in all), registered in Singapore. Services from AKAMAI-LINODE-AP Akamai Connected Cloud are reached through these addresses.

What it means to see AS63949 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS63949. That means the other end sits on the AKAMAI-LINODE-AP Akamai Connected Cloud network (Singapore). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
