how do you actually rotate your IPs?

Been looking into rotating residential proxies for scraping lately. Curious how you guys usually handle rotation.

Do you switch IPs on every request, stick with the same IP for a while, or just depends on the site?

I've tried Bright Data, Oxylabs, and IPnivo. All have been pretty good, but IPnivo feels like better value for the price.

What's worked best for you guys?
