What it means to see AS327943 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS327943. That means the other end sits on the MEZOBYTE network (South Africa). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
