A fingerprint browser isolates the account; the proxy decides how its network looks. Pick the wrong proxy type and even a perfectly isolated profile gets flagged. Here is how the main options differ and when to use each.

Datacenter proxies

IPs from cloud/hosting providers. Fast and cheap, but easy for platforms to identify as non-residential.

  • **Good for:** scraping public data, tasks where the site does not scrutinize network origin, high-volume automation on tolerant targets.
  • **Risky for:** logged-in accounts on strict platforms (social, marketplaces), where a datacenter IP under a "real person" account is an obvious tell.

Residential proxies

IPs assigned by ISPs to real homes. They look like ordinary users, at higher cost and usually lower speed.

  • **Good for:** logged-in accounts on strict platforms, region-sensitive tasks, anything where the account must look like a normal resident.
  • **Watch out for:** rotation. For a logged-in account you want a **stable** residential IP, not one that changes every request — a sender that "moves" each session looks compromised.

Mobile proxies

IPs from mobile carriers (4G/5G). The most trusted for the strictest platforms because many real users share carrier IPs, but the priciest.

  • **Good for:** the hardest accounts (aged social accounts, high-value assets) where residential still gets challenged.

ISP (static residential) proxies

Residential-looking IPs hosted in datacenters for stability — a middle ground: residential trust with datacenter speed and a fixed IP.

  • **Good for:** logged-in accounts that need both trust and a stable IP.

The rule that matters more than the type

Whatever type you choose, the proxy must be **consistent with the account's environment**. Timezone, language, and geolocation should match the IP's region. A US-timezone profile behind a German IP is a contradiction the platform sees regardless of how "residential" the IP is. (See [proxy alignment](/blog/proxy-alignment-checklist/).)

And keep **one stable proxy per profile**. Sharing one IP across many accounts clusters them; rotating a logged-in account's IP looks like a hijack.

Quick guidance

  • **Strict logged-in accounts (social, LinkedIn, marketplaces):** residential or mobile, stable, region-aligned.
  • **Scraping / tolerant automation:** datacenter is fine and cheaper.
  • **Need trust + a fixed IP:** ISP/static residential.
