What is AS8517?
An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS8517 was assigned to ULAKNET by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.
Reach on the internet
AS8517 currently announces 48 IPv4 block(s), totaling about 230.4 thousand addresses (230,400 in all), registered in Turkey. Services from ULAKNET are reached through these addresses.
What it means to see AS8517 on your network
When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS8517. That means the other end sits on the ULAKNET network (Turkey). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
How to see every connection and network your devices reach
Tracing one connection's ASN at a time is tedious. Sentinela, by PC Monitor, maps the devices on your network, shows what is exposed to the internet and helps flag suspicious connections and devices — running on your Windows. Meet Sentinela.
