There isn't a fixed average wait time for IP rotation because you can control the rotation interval based on your use case.
IP rotation times
Minimum wait time: 3 minutes (180 seconds)
Default wait time: 10 minutes if you don't set a custom interval
Maximum sticky session duration: 300 minutes
How can I control the rotation?
You have two main options:
Fast rotation: Use a random port to receive a new IP with each request.
Controlled rotation: Use a sticky session and set a custom rotation interval of 3 minutes or longer.
The appropriate rotation interval depends on how frequently you need to change your IP and whether you need to maintain the same IP for a period of time.
