AS64236: the UNREAL-SERVERS network

AS64236 is an internet Autonomous System operated by UNREAL-SERVERS (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 AS64236?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS64236 was assigned to UNREAL-SERVERS by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS64236 currently announces 21 IPv4 block(s), totaling about 20 thousand addresses (19,968 in all), registered in the United States. Services from UNREAL-SERVERS are reached through these addresses.

What it means to see AS64236 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS64236. That means the other end sits on the UNREAL-SERVERS network (the United States). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
