AS201446: the PROFESIONALHOSTING network

AS201446 is an internet Autonomous System operated by PROFESIONALHOSTING (Spain). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS201446?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS201446 was assigned to PROFESIONALHOSTING by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS201446 currently announces 17 IPv4 block(s), totaling about 10 thousand addresses (9,984 in all), registered in Spain. Services from PROFESIONALHOSTING are reached through these addresses.

What it means to see AS201446 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS201446. That means the other end sits on the PROFESIONALHOSTING network (Spain). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
