Buyer guides
Residential vs. datacenter proxies
Products that are all sold as “proxy IPs” are often not interchangeable. Choosing the wrong type can mean immediate blocks, unstable sessions, or a cost model that does not match your traffic.
Four common product types
Datacenter proxies
These IPs come from cloud platforms or data centers, not from household broadband subscribers. They are usually cheaper, lower-latency, and better suited to high-volume requests for public pages, API debugging, and automated tests. The trade-off is just as clear: many anti-bot and risk systems identify datacenter ranges. If a target site blocks them, success rates drop quickly.
Residential proxies
These IPs are assigned by consumer internet service providers to homes or similar users. They are often sold by traffic volume (per GB) and rotate by default. Because the exit looks more like a regular user, they are commonly used when a site filters datacenter IPs — for example ad verification, localized search results, or watching public e-commerce prices and stock. They cost more, and speed or stability is often lower than datacenter inventory. Read the provider's acceptable use policy and any description of how IPs are sourced.
Mobile proxies (4G / 5G)
These IPs come from cellular carrier networks. Some mobile-focused sites and risk models treat them more permissively, so they are often used for mobile ad verification and mobile-first page checks. Pools are typically smaller and prices are often the highest of the four types, which makes them a poor default for all high-traffic jobs.
ISP / static residential proxies
These addresses are usually registered in an internet service provider's name and may be hosted in a data-center environment, with an IP that can stay the same for a longer period. They are a better fit when you need the same exit for a while — for example a longer login session or repeated checks of a regional public page. They are not a universal substitute for rotating residential traffic, and they should not be assumed to be undetectable.
Match the product to the job
| What matters most | Start by looking at |
|---|---|
| Cost and speed, and the target does not block datacenter IPs | Datacenter proxies |
| The target often blocks datacenter IPs and you need a consumer-like exit | Rotating residential proxies |
| You need the same IP for a longer session | ISP / static residential, or residential products with sticky sessions |
| You mainly verify mobile ads or mobile sites | Mobile proxies |
| You are developing or testing against your own systems | Datacenter proxies are usually enough |
Session behavior matters as much as type
Rotating exits change IP between requests or after a short interval, which helps when you need to fetch many public pages without concentrating traffic on one address. Sticky or session-based exits try to keep the same IP for a period of time, which helps with multi-step flows. Before you buy, check how long a session can last, how it is bound (session ID, hostname, or something else), and how concurrent connections are counted. Those details often matter more than the product label.
Protocols and basic fit
HTTP, HTTPS, and SOCKS5 are the usual options. Confirm what your browser extension or tooling supports, whether the provider offers that protocol, how authentication works, and whether you can filter by country or city. Treat marketed coverage and success-rate figures as advertising copy and verify them with a small plan or trial.
