AS3316: the RELARN Research & Education Network network

AS3316 is an internet Autonomous System operated by RELARN Research & Education Network (Russia). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS3316?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS3316 was assigned to RELARN Research & Education Network by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS3316 currently announces 24 IPv4 block(s), totaling about 11 thousand addresses (11,008 in all), registered in Russia. Services from RELARN Research & Education Network are reached through these addresses.

What it means to see AS3316 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS3316. That means the other end sits on the RELARN Research & Education Network network (Russia). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
