AS57013: the EURASIA-STAR-AS network

AS57013 is an internet Autonomous System operated by EURASIA-STAR-AS (Kazakhstan). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS57013?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS57013 was assigned to EURASIA-STAR-AS by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS57013 currently announces 27 IPv4 block(s), totaling about 15.4 thousand addresses (15,360 in all), registered in Kazakhstan. Services from EURASIA-STAR-AS are reached through these addresses.

What it means to see AS57013 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS57013. That means the other end sits on the EURASIA-STAR-AS network (Kazakhstan). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
