Dedicated datacenter proxy meaning: how does it differ from other types?
Think of it as a hosting company address handed to one person. Nobody else is routed through it during your term, and since every request on it comes from your own jobs, the reputation behind that IP reflects your activity alone.
Residential proxies borrow household broadband lines, while datacenter proxies ride on server room uplinks. That gives them steady throughput and makes them well suited to long, high volume runs. Within the datacenter family, the shared plan splits each address among several buyers, whereas the private plan stays yours from day one to the last day.
Next to ISP proxies, private datacenter IPs cost less per address. ISP proxies are static IPs registered to consumer internet providers, so they read as regular subscribers. IPv6 plans go cheaper still but only reach sites that accept IPv6. Many teams mix two or three of these, matching each to the task.
