AS35000: the SEVEREN-TELECOM_TRANSIT SEVEREN-TELECOM network

AS35000 is an internet Autonomous System operated by SEVEREN-TELECOM_TRANSIT SEVEREN-TELECOM (Russia). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS35000?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS35000 was assigned to SEVEREN-TELECOM_TRANSIT SEVEREN-TELECOM by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS35000 currently announces 28 IPv4 block(s), totaling about 36.6 thousand addresses (36,608 in all), registered in Russia. Services from SEVEREN-TELECOM_TRANSIT SEVEREN-TELECOM are reached through these addresses.

What it means to see AS35000 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS35000. That means the other end sits on the SEVEREN-TELECOM_TRANSIT SEVEREN-TELECOM network (Russia). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
