What is AS8717?
An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS8717 was assigned to A1 by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.
Reach on the internet
AS8717 currently announces 273 IPv4 block(s), totaling about 217.6 thousand addresses (217,600 in all), registered in Bulgaria. Services from A1 are reached through these addresses.
What it means to see AS8717 on your network
When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS8717. That means the other end sits on the A1 network (Bulgaria). 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
