Newcomers to proxy IPs are often confused by terms such as "ISP proxy," "residential proxy," and "datacenter proxy." Many people encountering the term for the first time are unclear about how it differs from the more familiar residential and datacenter proxies. This article starts from the underlying principles and clarifies what it is, what advantages it offers, and which scenarios it suits.
I. Principles of ISP Proxies
ISP stands for Internet Service Provider, commonly referred to as a telecom carrier. IPs for this type of proxy are allocated directly by carriers, drawn from the same network resource pool used for ordinary residential IPs, giving them the network-level attributes of a real carrier IP.
Unlike pure residential proxies, these IPs originate from carrier networks but are hosted on datacenter servers, uniformly maintained and allocated by the proxy provider, delivering a usage experience closer to the stability and access speed of datacenter proxies. For this reason, the industry often refers to this type as a "datacenter-grade residential IP," a solution positioned between residential and datacenter proxies: it combines the real identity of a carrier network with the stable operating conditions of a datacenter environment.
II. How ISP Proxies Differ from Other Proxy Types
1. Compared with Residential Proxies
IPs for ordinary residential proxies come directly from end users' home broadband connections and change along with fluctuations in the user's network connection, resulting in relatively low stability. ISP proxy IPs likewise originate from carrier networks, but are hosted within the provider's datacenter environment and can remain fixed for an agreed period.
2. Compared with Datacenter Proxies
IP ranges for traditional datacenter proxies are typically registered directly under datacenter ownership, with network characteristics that differ noticeably from ordinary residential IPs, making them prone to detection by platform risk control systems as non-residential network traffic. IP ranges for this type of solution, by contrast, are registered under carrier ownership, with network characteristics closer to real users, making detection comparatively more difficult.
In short, ISP proxies combine the real identity of residential proxies with the stability of datacenter proxies, forming a compromise solution between the two. This is also why they are widely used in scenarios requiring long-term, stable logins.
III. Core Advantages
Strong stability: Exit IPs remain fixed for an agreed period, suiting account-based scenarios that require maintaining the same login state over the long term, without frequent network environment changes interrupting login records.
High network authenticity: IP ranges are registered under carrier ownership, making them less likely than datacenter-based solutions to be judged by platforms as non-organic traffic sources.
Reliable access speed: Hosted within professional datacenter environments, line quality and response speed generally exceed those of ordinary residential networks, suiting business scenarios with certain access speed requirements.
IV. Applicable Scenarios
This type of solution suits scenarios requiring long-term, stable logins along with network authenticity requirements, such as multi-account operations on social media platforms like TikTok, multi-store management on e-commerce platforms like Amazon, and maintenance of advertising accounts requiring long-term logins. A common feature of these scenarios: accounts need to maintain a consistent login environment over an extended period, weight or trust accumulates over time, and network environment stability directly affects whether this accumulation process remains uninterrupted.
For business requirements leaning toward short-duration, high-frequency tasks covering multiple regions, such as scraping, price comparison, or ad landing page verification, solutions like Dynamic Residential Proxies, which rotate exit IPs by session or by request, are more suitable. For account operations requiring a long-term stable identity, ISP proxies are the better-fitting choice. A previous article, "Dynamic Residential Proxies vs. Long Acting ISP Proxies," compared the applicable scenarios of these two solution types in detail and can serve as further reference for specific business requirements.
V. What 9HTTP's Long Acting ISP Proxies Look Like Specifically
Turning to the specific product, this 9HTTP product line follows exactly the logic described above: real carrier identity combined with stable datacenter operation. The lock period is fixed at 30 days, exit IPs come from real carrier networks, coverage spans over 200 countries and regions, and target markets can be selected by region directly. As for how well the lines actually perform, two figures tell the story: average response time under 500 milliseconds and service availability around 99.9%. These two factors determine whether high-frequency operations such as TikTok multi-account management and Amazon multi-store management run smoothly. Pricing starts from $2.80 per IP per month, configured according to account volume. For business requirements that also involve short-duration, high-frequency tasks such as scraping, 9HTTP's Dynamic Residential Proxies can be used alongside this product line.
Understanding the principles behind this type of proxy essentially means understanding the balance it strikes between authenticity and stability. Before selecting a proxy type, determining which side the business prioritizes more often helps a team reach the right choice than comparing prices alone.
