What is AS37090?
An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS37090 was assigned to ISOCEL by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

AS37090 currently announces 10 IPv4 block(s), totaling about 23.6 thousand addresses (23,552 in all), registered in BJ. Services from ISOCEL are reached through these addresses.
What it means to see AS37090 on your network
When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS37090. That means the other end sits on the ISOCEL network (BJ). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
