What it means to see AS44559 on your network
When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS44559. That means the other end sits on the ITHOSTLINE network (CY). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
