How many different proxies do you have?

It depends on the proxy type:

• Datacenter rotating (backconnect) proxies: a pool of 700,000+ IPs.
• Residential rotating proxies: a pool of 20M+ residential IPs.
• Private dedicated proxies: you get your own static IPs, as many as your package includes.

With rotating proxies you don't get a list of single proxies: you get gateway IP:PORTs, and every request (or every few minutes) goes out through a new IP from the pool. How it works.
