What is AS8119?
An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS8119 was assigned to DTN-AS by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.
Reach on the internet
AS8119 currently announces 9 IPv4 block(s), totaling about 6.1 thousand addresses (6,144 in all), registered in the United States. Services from DTN-AS are reached through these addresses.
What it means to see AS8119 on your network
When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS8119. That means the other end sits on the DTN-AS network (the United States). 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
