AS17077: the BROADCAST-NETWORKS network

AS17077 is an internet Autonomous System operated by BROADCAST-NETWORKS (the United States). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS17077?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS17077 was assigned to BROADCAST-NETWORKS by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS17077 currently announces 11 IPv4 block(s), totaling about 10.8 thousand addresses (10,752 in all), registered in the United States. Services from BROADCAST-NETWORKS are reached through these addresses.

What it means to see AS17077 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS17077. That means the other end sits on the BROADCAST-NETWORKS network (the United States). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
