This page shows the leading network operators (ASNs) in , ranked by their observed IP address presence and routing footprint.

What are Autonomous System Numbers (ASNs)?

An Autonomous System Number (ASN) is a unique identifier assigned to a network operator that manages a collection of IP prefixes and routing policies on the internet.

ASNs are typically operated by Internet Service Providers (ISPs), mobile carriers, data centers, cloud providers, and large enterprises. They play a critical role in global internet routing and traffic exchange.

Why ASN rankings in matter

Understanding ASN distribution helps network engineers, CDN operators, and researchers evaluate how internet connectivity is structured within a country.

• Identify dominant ISPs and backbone providers
• Analyze routing diversity and market concentration
• Support traffic optimization and network planning
• Assist in regional performance and resilience analysis

Data sources and methodology

The ASN ranking data on Aleiwa is generated using a combination of public routing information and active network measurements.

• Public BGP routing tables and ASN announcements
• IP-to-AS mapping datasets
• Observed IP address distribution by country
• Regular data validation and update processes

Percentages shown represent the estimated share of IP address presence within the country and their proportion relative to the global internet.

How to use this ASN data

This ASN ranking data can be used in various real-world scenarios:

• CDN traffic steering and cache deployment planning
• ISP market analysis and competitive research
• Network troubleshooting and routing analysis
• Academic research on internet infrastructure
