How can I get random IP address for testing purposes? or What’s the best way to get random IP address

Why not just use mock IPs in your code? Like, 192.168.x.x or 10.x.x.x ranges.

If you need *real* external IPs, scraping free proxy lists is risky—most are dead or malicious.

Maybe try Storm Proxies? Cheap and rotates IPs automatically.
