AS37352: the CloudAfrica network

AS37352 is an internet Autonomous System operated by CloudAfrica (South Africa). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS37352?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS37352 was assigned to CloudAfrica by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS37352 currently announces 2 IPv4 block(s), totaling about 2 thousand addresses (2,048 in all), registered in South Africa. Services from CloudAfrica are reached through these addresses.

What it means to see AS37352 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS37352. That means the other end sits on the CloudAfrica network (South Africa). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
