AS18664: the VELOCITY-BNA network

AS18664 is an internet Autonomous System operated by VELOCITY-BNA (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 AS18664?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS18664 was assigned to VELOCITY-BNA by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS18664 currently announces 3 IPv4 block(s), totaling about 8.4 thousand addresses (8,448 in all), registered in the United States. Services from VELOCITY-BNA are reached through these addresses.

What it means to see AS18664 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS18664. That means the other end sits on the VELOCITY-BNA network (the United States). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
