The 'Randomize IP' feature at Packet Stream rotates residential IP addresses after every executed request to the proxy. A new IP is issued randomly for every request. This solution works best for most use cases. Whereas a 'Sticky IP' feature assigns a single static residential IP that is available for re-usage for numerous connections during a session. Sticky IPs remain static and operate until the session is disabled. This solution works best if you require a non-changing residential IP for different requests.
