What is AS30838?
An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS30838 was assigned to TELPOL by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.
Reach on the internet
AS30838 currently announces 11 IPv4 block(s), totaling about 34.3 thousand addresses (34,304 in all), registered in Poland. Services from TELPOL are reached through these addresses.
What it means to see AS30838 on your network
When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS30838. That means the other end sits on the TELPOL network (Poland). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
