What it means to see AS18144 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS18144. That means the other end sits on the AS-ENECOM Enecom,Inc. network (Japan). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
