What it means to see AS12771 on your network
When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS12771. That means the other end sits on the MEDIAMETRIE-AS network (France). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
