What is AS12831?
An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS12831 was assigned to TASK-AS by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.
Reach on the internet
AS12831 currently announces 10 IPv4 block(s), totaling about 27.6 thousand addresses (27,648 in all), registered in Poland. Services from TASK-AS are reached through these addresses.
What it means to see AS12831 on your network
When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS12831. That means the other end sits on the TASK-AS network (Poland). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
