AS1902: the PAN-NET Deutsche Telekom Pan-Net s.r.o. network

AS1902 is an internet Autonomous System operated by PAN-NET Deutsche Telekom Pan-Net s.r.o. (Slovakia). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS1902?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS1902 was assigned to PAN-NET Deutsche Telekom Pan-Net s.r.o. by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS1902 currently announces 3 IPv4 block(s), totaling about 5.4 thousand addresses (5,376 in all), registered in Slovakia. Services from PAN-NET Deutsche Telekom Pan-Net s.r.o. are reached through these addresses.

What it means to see AS1902 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS1902. That means the other end sits on the PAN-NET Deutsche Telekom Pan-Net s.r.o. network (Slovakia). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
