AS41798: the TTC-AS JSC Transtelecom network

AS41798 is an internet Autonomous System operated by TTC-AS JSC Transtelecom (Kazakhstan). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS41798?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS41798 was assigned to TTC-AS JSC Transtelecom by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS41798 currently announces 34 IPv4 block(s), totaling about 46.1 thousand addresses (46,080 in all), registered in Kazakhstan. Services from TTC-AS JSC Transtelecom are reached through these addresses.

What it means to see AS41798 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS41798. That means the other end sits on the TTC-AS JSC Transtelecom network (Kazakhstan). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
