AS56089: the OFFRATEL-AS-AP OFFRATEL network

AS56089 is an internet Autonomous System operated by OFFRATEL-AS-AP OFFRATEL (NC). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS56089?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS56089 was assigned to OFFRATEL-AS-AP OFFRATEL by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS56089 currently announces 7 IPv4 block(s), totaling about 36.1 thousand addresses (36,096 in all), registered in NC. Services from OFFRATEL-AS-AP OFFRATEL are reached through these addresses.

What it means to see AS56089 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS56089. That means the other end sits on the OFFRATEL-AS-AP OFFRATEL network (NC). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
