The ASN (Autonomous System Number) object represents a network or group of networks operated by a single organization in the Byteful system. ASNs are globally unique identifiers assigned to organizations that control blocks of IP addresses, such as internet service providers, hosting companies, and large enterprises.

Key Attributes

​
Object Relationships

The ASN object connects with several other objects in the Byteful API:
  • Proxies: ASNs are assigned to specific proxies, determining their network identity
  • IP Addresses: Each IP address belongs to an ASN
  • Subnets: Groups of IP addresses within an ASN
  • Services: Proxy services may be filtered or targeted by ASN
  • Countries: ASNs are typically associated with specific countries

​
Usage Notes

  • ASNs provide important context about the quality, type, and reputation of proxies
  • For residential proxies, you can target specific ASNs in the /residential/list endpoint
  • For mobile proxies, you can target specific ASNs in the /mobile/list endpoint
  • The asn_ip_address_count gives an indication of the size and potential diversity of IPs within an ASN

​
ASN Type Categories

ASNs are categorized into several types, each with distinct characteristics: When selecting proxies for specific use cases, the ASN type often matters more than the specific ASN itself, as it indicates the general traffic pattern and reputation of the network.
