An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS31257 was assigned to ORIONNET-KRK by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

AS31257 currently announces 10 IPv4 block(s), totaling about 46.1 thousand addresses (46,080 in all), registered in Russia. Services from ORIONNET-KRK are reached through these addresses.
What it means to see AS31257 on your network
When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS31257. That means the other end sits on the ORIONNET-KRK network (Russia). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
