AS9729: the IS-AP iAdvantage Limited network

AS9729 is an internet Autonomous System operated by IS-AP iAdvantage 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 AS9729?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS9729 was assigned to IS-AP iAdvantage Limited by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS9729 currently announces 42 IPv4 block(s), totaling about 85 thousand addresses (84,992 in all), registered in Hong Kong. Services from IS-AP iAdvantage Limited are reached through these addresses.

What it means to see AS9729 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS9729. That means the other end sits on the IS-AP iAdvantage Limited network (Hong Kong). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
