AS28110: the NAVEGALO S.A. network

AS28110 is an internet Autonomous System operated by NAVEGALO S.A. (Costa Rica). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS28110?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS28110 was assigned to NAVEGALO S.A. by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS28110 currently announces 26 IPv4 block(s), totaling about 10.8 thousand addresses (10,752 in all), registered in Costa Rica. Services from NAVEGALO S.A. are reached through these addresses.

What it means to see AS28110 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS28110. That means the other end sits on the NAVEGALO S.A. network (Costa Rica). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
