system and target websites.<\/p>\n\n\n\n<p>Instead of sending requests directly from a single origin IP address, traffic is routed through a distributed proxy network.<\/p>\n\n\n\n<p>This abstraction layer allows request sources to be distributed across multiple IP addresses, reducing the dependency on a single network identity.<\/p>\n\n\n\n<p>A typical proxy network used in web scraping environments includes:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Residential proxy networks<\/li>\n\n\n\n<li>Datacenter proxy infrastructure<\/li>\n\n\n\n<li>Rotating proxy
