AS15180: the DIGITALSERVICES.UOL S.A. network

AS15180 is an internet Autonomous System operated by DIGITALSERVICES.UOL S.A. (Brazil). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS15180?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS15180 was assigned to DIGITALSERVICES.UOL S.A. by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS15180 currently announces 20 IPv4 block(s), totaling about 145.7 thousand addresses (145,664 in all), registered in Brazil. Services from DIGITALSERVICES.UOL S.A. are reached through these addresses.

What it means to see AS15180 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS15180. That means the other end sits on the DIGITALSERVICES.UOL S.A. network (Brazil). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
