AS204226: the I-TECO I-Teco 32-bit autonomous system 1 network

AS204226 is an internet Autonomous System operated by I-TECO I-Teco 32-bit autonomous system 1 (Russia). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS204226?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS204226 was assigned to I-TECO I-Teco 32-bit autonomous system 1 by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS204226 currently announces 2 IPv4 block(s), totaling about 1.3 thousand addresses (1,280 in all), registered in Russia. Services from I-TECO I-Teco 32-bit autonomous system 1 are reached through these addresses.

What it means to see AS204226 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS204226. That means the other end sits on the I-TECO I-Teco 32-bit autonomous system 1 network (Russia). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
