AS50049: the RSL-AS-AP RedSwitches network

AS50049 is an internet Autonomous System operated by RSL-AS-AP RedSwitches (the Netherlands). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS50049?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS50049 was assigned to RSL-AS-AP RedSwitches by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS50049 currently announces 52 IPv4 block(s), totaling about 17.2 thousand addresses (17,152 in all), registered in the Netherlands. Services from RSL-AS-AP RedSwitches are reached through these addresses.

What it means to see AS50049 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS50049. That means the other end sits on the RSL-AS-AP RedSwitches network (the Netherlands). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
