AS12618: the PL-BYDMAN-COM Commercial Users network

AS12618 is an internet Autonomous System operated by PL-BYDMAN-COM Commercial Users (Poland). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS12618?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS12618 was assigned to PL-BYDMAN-COM Commercial Users by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS12618 currently announces 11 IPv4 block(s), totaling about 31 thousand addresses (30,976 in all), registered in Poland. Services from PL-BYDMAN-COM Commercial Users are reached through these addresses.

What it means to see AS12618 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS12618. That means the other end sits on the PL-BYDMAN-COM Commercial Users network (Poland). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
