What is the difference between static residential (ISP) proxies and datacenter proxies?

ISP proxies are hosted in datacenters but instead of using IP addresses that do not belong to an ISP, they partner with ISPs to provide them with residential IP addresses.

IPs that aren’t associated with an ISP are easier to block than those used by ISP proxies. Using real IP addresses makes it harder for the target website to detect the web scraping activity.
