AS35807: the AS-SKYNET-SPB network

AS35807 is an internet Autonomous System operated by AS-SKYNET-SPB (Russia). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS35807?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS35807 was assigned to AS-SKYNET-SPB by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS35807 currently announces 26 IPv4 block(s), totaling about 308 thousand addresses (307,968 in all), registered in Russia. Services from AS-SKYNET-SPB are reached through these addresses.

What it means to see AS35807 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS35807. That means the other end sits on the AS-SKYNET-SPB network (Russia). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
