Anyone who has worked in cross-border e-commerce, social media operations, or data collection is definitely familiar with proxy IPs.
As a proxy service provider covering over 200 countries worldwide and maintaining a pool of more than 80 million residential IPs, 9HTTP processes massive proxy requests from various industries every day. We have found that more than 60% of new users are initially unsure whether to choose dynamic residential proxies or long-term ISP proxies.
In this article, we will break down the differences based on real business scenarios to help you clearly understand: what is the difference between dynamic residential proxies and long-term ISP proxies? Which one is more suitable for your business?
I. What Are Dynamic Residential Proxies?
Dynamic residential proxies use real residential broadband IP addresses, with IPs rotating automatically per request or at predefined time intervals.
Core Features:
Automatic IP rotation — Each request uses a different IP, significantly reducing the risk of being blocked by target websites
Real residential IPs — Sourced from genuine home networks around the world, extremely high anonymity
Pay-as-you-go pricing — $0.55/GB, only pay for what you use, no monthly fee burden
Precise geo-targeting — Supports IP locations in 200+ countries and regions
Typical Use Cases:
| Scenario | Why Dynamic Residential Proxies Are Suitable |
| Web data scraping | High-frequency requests require continuous IP changes to avoid anti-scraping systems |
| E-commerce price monitoring | Simulates real users from different regions to check competitor pricing |
| SEO ranking tracking | Mimics real search behavior to obtain accurate regional ranking data |
| Large-scale data collection | IP rotation is key to maintaining success rates under high concurrency |
9HTTP dynamic residential proxies provide an 80 million+ residential IP pool, an average response time of under 500ms, and 99.9% service availability, making them an excellent choice for high-frequency data collection scenarios.
II. What Are Long-Term ISP Proxies?
Long-term ISP proxies provide fixed, unchanging ISP IP addresses, suitable for businesses that require stable long-term connections.
Core Features:
Static IP stability — The same IP can be used continuously for months
Account binding friendly — One account corresponds to one fixed IP, reducing correlation risks
Strong session persistence — Stable login status, less likely to disconnect
Per IP monthly pricing — Starting from $3.2/IP/month, more cost-effective for bulk purchases
Typical Use Cases:
| Scenario | Why Long-Term ISP Proxies Are Suitable |
| Multi-account management | Each account is bound to an independent fixed IP for secure isolation |
| Cross-border e-commerce store operations | Overseas store accounts require stable long-term logins; frequent IP changes may trigger risk controls |
| Social media account management | Fixed IP helps build account trust and reduces abnormal account risks |
9HTTP long-term ISP proxies provide high availability guarantees and a real-time monitoring dashboard, making them a reliable infrastructure for account-based operations.
