Every IP address belongs to a network, and every network has a number. Looking up an address returns that number and the owner's name. This is how a website tells a home connection from a server: the owner is either a consumer internet provider, a phone carrier or a hosting company.
The three kinds of proxy differ in exactly this. A residential proxy exits from a home provider's network, a mobile proxy from a carrier's, a datacenter proxy from a host's. Bot filters weigh the network heavily when deciding whether to trust a visitor.
Questions about ASN
How do I look up the ASN of an IP address?
Any IP lookup or whois tool shows it, along with the owner's name. The owner tells you at once whether the address is on a home provider, a carrier or a hosting network.
Can I choose the ASN of my proxy?
Some services let you pick a provider. On BooProxies you choose the kind of network, residential, mobile or datacenter, and the country; the provider within that is picked for you.
