The essential points from this guide -- each one is explained in detail below.
Dedicated proxies are used by one customer only, protecting IP reputation from other users' activity.
They cost more than shared proxies but offer consistent performance and lower ban rates.
Dedicated datacenter proxies start around $1-3/IP/month; dedicated residential proxies are priced per GB.
Best for tasks where IP reputation directly impacts success: account management, ad verification, and brand monitoring.
Anti-bot systems maintain reputation scores for IP addresses based on historical behavior. An IP that has sent thousands of automated requests, triggered CAPTCHAs, or been flagged for abuse carries a low reputation score. When you use a shared proxy, other customers' actions affect the IP's reputation before your request even arrives.
With a dedicated proxy, the IP's reputation is entirely in your hands. If you follow best practices (reasonable request rates, proper headers, realistic timing), the IP maintains a clean reputation. This translates directly to higher success rates -- dedicated IPs on well-managed accounts consistently outperform shared IPs on protected targets.
On permissive targets (APIs, data feeds, small websites), the performance difference between dedicated and shared proxies is negligible. Both achieve near-100% success rates because the target does not aggressively filter by IP reputation. The gap emerges on protected targets with anti-bot systems.
On moderately protected targets, dedicated proxies typically achieve 90-99% success rates compared to 70-90% for shared proxies. On heavily protected targets (major retailers, social platforms), dedicated proxies maintain 80-95% success while shared proxies may drop to 40-60%. The exact numbers depend on pool management, but the pattern is consistent: exclusive use means better reputation means higher success.
Choose dedicated proxies when IP reputation directly impacts your task outcome. Account management tasks (social media, e-commerce) require clean IPs because platforms link account trust to IP history. Ad verification campaigns need dedicated IPs to avoid being pre-flagged by ad networks. Brand monitoring workflows benefit from consistent, trusted IPs that are not polluted by other users' scraping activity.
For high-volume web scraping of protected targets, dedicated rotating residential proxies offer the best combination of exclusivity and scale. The pool assigned to your account rotates only your traffic, so ban rates remain low even at scale. For budget-conscious scraping of permissive targets, shared proxies deliver comparable results at a fraction of the cost.
Dedicated datacenter proxies are the most affordable, typically $1-3/IP/month or $0.02-0.10/IP/day. At KnoxProxy, dedicated datacenter proxies start at $0.02/IP/day with volume discounts. Dedicated ISP proxies cost $3-10/IP/month. Dedicated residential proxy pools are priced per GB (like shared residential) but with a premium for the exclusivity guarantee -- typically 20-50% above shared rates.
The cost premium for dedicated proxies is justified when the alternative is wasted requests. If a shared proxy has a 70% success rate on your target and a dedicated proxy achieves 95%, the dedicated proxy is more cost-effective despite the higher per-unit price because you waste fewer requests and consume less bandwidth on retries.
