AS55044: the LRCSNET network

AS55044 is an internet Autonomous System operated by LRCSNET (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 AS55044?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS55044 was assigned to LRCSNET by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS55044 currently announces 11 IPv4 block(s), totaling about 12.8 thousand addresses (12,800 in all), registered in the United States. Services from LRCSNET are reached through these addresses.

What it means to see AS55044 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS55044. That means the other end sits on the LRCSNET network (the United States). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
