What is AS35258?
An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS35258 was assigned to ITOSS by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.
Reach on the internet
AS35258 currently announces 10 IPv4 block(s), totaling about 9.5 thousand addresses (9,472 in all), registered in Germany. Services from ITOSS are reached through these addresses.
What it means to see AS35258 on your network
When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS35258. That means the other end sits on the ITOSS network (Germany). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
