AS39435: the EVOLGOGRAD-AS network

AS39435 is an internet Autonomous System operated by EVOLGOGRAD-AS (Russia). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS39435?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS39435 was assigned to EVOLGOGRAD-AS by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS39435 currently announces 19 IPv4 block(s), totaling about 70.1 thousand addresses (70,144 in all), registered in Russia. Services from EVOLGOGRAD-AS are reached through these addresses.

What it means to see AS39435 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS39435. That means the other end sits on the EVOLGOGRAD-AS network (Russia). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
