What it means to see AS7678 on your network
When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS7678. That means the other end sits on the PROX Prox System Design Inc. network (Japan). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
