AS25373: the GOVSK-AS The Slovak Republic Government Office network

AS25373 is an internet Autonomous System operated by GOVSK-AS The Slovak Republic Government Office (Slovakia). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS25373?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS25373 was assigned to GOVSK-AS The Slovak Republic Government Office by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS25373 currently announces 4 IPv4 block(s), totaling about 2.6 thousand addresses (2,560 in all), registered in Slovakia. Services from GOVSK-AS The Slovak Republic Government Office are reached through these addresses.

What it means to see AS25373 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS25373. That means the other end sits on the GOVSK-AS The Slovak Republic Government Office network (Slovakia). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
