The number AS45014 was assigned to HOSTIT-MK-AS Milton Keynes Facility by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

What it means to see AS45014 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS45014. That means the other end sits on the HOSTIT-MK-AS Milton Keynes Facility network (the United Kingdom). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
