AS3215: the France Telecom - Orange network

AS3215 is an internet Autonomous System operated by France Telecom - Orange (France). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS3215?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS3215 was assigned to France Telecom - Orange by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS3215 currently announces 247 IPv4 block(s), totaling about 20.1 million addresses (20,081,152 in all), registered in France. Services from France Telecom - Orange are reached through these addresses.

What it means to see AS3215 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS3215. That means the other end sits on the France Telecom - Orange network (France). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
