AS12975: the PALTEL-AS PALTEL Autonomous System network

AS12975 is an internet Autonomous System operated by PALTEL-AS PALTEL Autonomous System (PS). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS12975?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS12975 was assigned to PALTEL-AS PALTEL Autonomous System by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS12975 currently announces 194 IPv4 block(s), totaling about 543.2 thousand addresses (543,232 in all), registered in PS. Services from PALTEL-AS PALTEL Autonomous System are reached through these addresses.

What it means to see AS12975 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS12975. That means the other end sits on the PALTEL-AS PALTEL Autonomous System network (PS). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
