AS12897 is an internet Autonomous System operated by ENTEGAMEDIANET ENTEGA Medianet GmbH (Germany). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS12897?

The number AS12897 was assigned to ENTEGAMEDIANET ENTEGA Medianet GmbH by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

What it means to see AS12897 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS12897. That means the other end sits on the ENTEGAMEDIANET ENTEGA Medianet GmbH network (Germany). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
