Network routing
Autonomous Systems are groups of networks that participate in global internet routing. They are typically managed by companies, organizations, governments, or other entities. Each autonomous system is assigned a unique number that identifies them called an Autonomous System Number (ASN). When your phone connects to the internet, it's assigned an IP address that is managed by the autonomous system. The autonomous system then determines how that traffic is routed to and from the internet. Below are the autonomous systems used by Claro for its cellular network.
