AS9925 is an internet Autonomous System operated by HKTDCS-AS-AP VDC Powerbase Hong Kong Data Centers Limited (Hong Kong). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS9925?

All traffic entering or leaving that network is announced under this number.

What it means to see AS9925 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS9925. That means the other end sits on the HKTDCS-AS-AP VDC Powerbase Hong Kong Data Centers Limited network (Hong Kong). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
