When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS141866. That means the other end sits on the PARAMTEC-AS Param Technologies network (India). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
