AS49158: the WIFINITY network

AS49158 is an internet Autonomous System operated by WIFINITY (the United Kingdom). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS49158?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS49158 was assigned to WIFINITY by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS49158 currently announces 2 IPv4 block(s), totaling about 24.6 thousand addresses (24,576 in all), registered in the United Kingdom. Services from WIFINITY are reached through these addresses.

What it means to see AS49158 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS49158. That means the other end sits on the WIFINITY network (the United Kingdom). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
