AS55933: the CLOUDIE-AS-AP Cloudie Limited network

AS55933 is an internet Autonomous System operated by CLOUDIE-AS-AP Cloudie 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 AS55933?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS55933 was assigned to CLOUDIE-AS-AP Cloudie Limited by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS55933 currently announces 116 IPv4 block(s), totaling about 89.1 thousand addresses (89,088 in all), registered in Hong Kong. Services from CLOUDIE-AS-AP Cloudie Limited are reached through these addresses.

What it means to see AS55933 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS55933. That means the other end sits on the CLOUDIE-AS-AP Cloudie Limited network (Hong Kong). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
