Rotating vs Static at a Glance
| Aspect | Rotating | Static |
|---|---|---|
| What you connect to | One gateway; the provider picks the exit IP | The proxy address itself |
| Exit IP | Changes per request or per session | Always the same |
| How many addresses | Shares a pool of thousands or millions | Exactly the ones you bought |
| Session control | Sticky sessions for minutes at a time | As long as you like |
| Good for | Many independent requests to public pages | Logins, allowlists, long sessions, consistent location |
| Watch out for | Addresses shared with other users; less predictable | Spreading load is up to you |
How a Rotating Proxy Works
You configure one host and port, sometimes called a backconnect gateway. Behind it, the provider holds a pool of addresses. Each new connection, or each request, leaves through a different one. Most services let you shape this through the username: a country or city, and a session ID that keeps the same IP for a few minutes (a sticky session). From your code it looks like a single proxy:
# Every run may come out of a different address curl -x http://USER:[email protected]:8000 https://api.ipify.org
How a Static Proxy Works
A static proxy is one address, and every request through it leaves from that address. An ISP proxy is a static address registered to an internet provider rather than a hosting company, which is why websites see it as an ordinary home connection. If you need several, you buy several and decide in your own code which job uses which. ISP vs residential vs datacenter proxies explains the different kinds of address.
Which One You Need
- Static: managing accounts, anything with a login, APIs or partners that allowlist your IP, ad and listing checks from one consistent location, long-running browser sessions.
- Rotating: large numbers of independent requests to public pages, where no single address should carry much of the load.
Either way, keep within each site's terms and rate limits. A proxy changes where traffic comes from, not whether it is welcome. Before relying on any proxy, test its IP, location and speed.
