AS13807: the GREAT-PLAINS-COMMUNICATIONS network

AS13807 is an internet Autonomous System operated by GREAT-PLAINS-COMMUNICATIONS (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 AS13807?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS13807 was assigned to GREAT-PLAINS-COMMUNICATIONS by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS13807 currently announces 53 IPv4 block(s), totaling about 76.5 thousand addresses (76,544 in all), registered in the United States. Services from GREAT-PLAINS-COMMUNICATIONS are reached through these addresses.

What it means to see AS13807 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS13807. That means the other end sits on the GREAT-PLAINS-COMMUNICATIONS network (the United States). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
