AS50019: the DYNET-AS Dynamic NET Telekomunikasyon network

AS50019 is an internet Autonomous System operated by DYNET-AS Dynamic NET Telekomunikasyon (Turkey). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS50019?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS50019 was assigned to DYNET-AS Dynamic NET Telekomunikasyon by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS50019 currently announces 2 IPv4 block(s), totaling about 2 thousand addresses (2,048 in all), registered in Turkey. Services from DYNET-AS Dynamic NET Telekomunikasyon are reached through these addresses.

What it means to see AS50019 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS50019. That means the other end sits on the DYNET-AS Dynamic NET Telekomunikasyon network (Turkey). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
