AS54201: the WEWORK-MANAGEMENT-LLC network

AS54201 is an internet Autonomous System operated by WEWORK-MANAGEMENT-LLC (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 AS54201?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS54201 was assigned to WEWORK-MANAGEMENT-LLC by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS54201 currently announces 7 IPv4 block(s), totaling about 2 thousand addresses (2,048 in all), registered in the United States. Services from WEWORK-MANAGEMENT-LLC are reached through these addresses.

What it means to see AS54201 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS54201. That means the other end sits on the WEWORK-MANAGEMENT-LLC network (the United States). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
