AS36916: the X-DSL-NET1 network

AS36916 is an internet Autonomous System operated by X-DSL-NET1 (South Africa). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS36916?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS36916 was assigned to X-DSL-NET1 by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS36916 currently announces 25 IPv4 block(s), totaling about 73.7 thousand addresses (73,728 in all), registered in South Africa. Services from X-DSL-NET1 are reached through these addresses.

What it means to see AS36916 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS36916. That means the other end sits on the X-DSL-NET1 network (South Africa). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
