AS8735: the ATOS-DE-NUREMBERG network

AS8735 is an internet Autonomous System operated by ATOS-DE-NUREMBERG (Germany). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS8735?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS8735 was assigned to ATOS-DE-NUREMBERG by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS8735 currently announces 10 IPv4 block(s), totaling about 7.4 thousand addresses (7,424 in all), registered in Germany. Services from ATOS-DE-NUREMBERG are reached through these addresses.

What it means to see AS8735 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS8735. That means the other end sits on the ATOS-DE-NUREMBERG network (Germany). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
