What it means to see AS24139 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS24139. That means the other end sits on the WASUHZ Huashu media&Network Limited network (China). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
