The proxies come with a sticky session, ensuring each session lasts for a minimum of 60 minutes. Meanwhile, the end IPs behind the proxies are replaced randomly when they're inactive. For instance, if you choose a plan with 500 IPs, you'll receive 500 unique IPs at any given moment. Over a 30-day cycle, you could access up to 750 unique IPs, with a variation rate of 50%—a process executed at random.
