What is AS26552?
An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS26552 was assigned to PROMCAP by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.
Reach on the internet
AS26552 currently announces 1 IPv4 block(s), totaling 256 addresses (256 in all), registered in the United States. Services from PROMCAP are reached through these addresses.
What it means to see AS26552 on your network
When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS26552. That means the other end sits on the PROMCAP network (the United States). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
