AS16117 is an internet Autonomous System operated by GAVLENET se.gavlenet Autonomous System (Sweden). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS16117?

The number AS16117 was assigned to GAVLENET se.gavlenet Autonomous System by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

What it means to see AS16117 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS16117. That means the other end sits on the GAVLENET se.gavlenet Autonomous System network (Sweden). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
