AS28417: the Universidad Autonoma de Chiapas network

What is AS28417?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS28417 was assigned to Universidad Autonoma de Chiapas by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS28417 currently announces 8 IPv4 block(s), totaling about 10 thousand addresses (9,984 in all), registered in Mexico. Services from Universidad Autonoma de Chiapas are reached through these addresses.

What it means to see AS28417 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS28417. That means the other end sits on the Universidad Autonoma de Chiapas network (Mexico). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
