What it means to see AS133301 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS133301. That means the other end sits on the DWANIRINN-AS DWANIRINN network (India). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
