Every proxy routes your traffic through another IP — but that IP's reputation is what decides whether you sail through or get blocked. Datacenter, residential, mobile and premium residential proxies sit at very different trust levels. Here's how they compare and which to pick for what.
The anonymity hierarchy
From easiest to detect to most trusted, proxies rank like this:
- Datacenter — fastest and cheapest, but server IPs that sites flag most easily.
- Residential — real home IPs; you look like an ordinary user. The reliable all-rounder.
- Mobile — carrier IPs shared by thousands of phones; extremely hard to ban wholesale.
- Premium residential — hand-picked, near-flawless residential IPs; the highest trust, usually CAPTCHA-free.
Datacenter proxies
Hosted in data centers, these are the fastest and cheapest proxies — ideal for high-speed tasks on sites that don't scrutinise IPs. The catch: their ranges are public and well-known, so strict targets (sneakers, social, streaming) flag them quickly. Best for volume where trust isn't critical.
Residential proxies
Residential proxies exit through real home / ISP IP addresses, so to a website you look like an ordinary person at home — because on the network you are. That trust makes them the reliable all-rounder for scraping, account work and unblocking. At Proxysterr residential goes as low as $1/GB, and on rotating mode your IP changes constantly, so there's effectively no single-IP ban risk — more on that in our sticky vs rotating proxies guide.
Mobile proxies
Mobile proxies exit through mobile-carrier (4G/5G) IPs — the kind assigned to real phones over SIM / carrier data. Because one carrier IP is shared by thousands of real users, a network can't ban it without hitting genuine customers, which makes mobile proxies extremely resistant to blocks. They work best used the way they're sourced — over mobile carrier data — for the most authentic footprint. Ideal for the hardest social and app targets.
Premium residential proxies
Premium residential is the top tier: hand-selected, near-flawless residential IPs with the cleanest reputation, so they're usually CAPTCHA-free and far more effective for heavy scraping and maximum anonymity. They cost more — from $2/GB at Proxysterr — but for scrapers and anyone who has to pass the strictest checks, the near-zero friction pays for itself. (Premium residential is coming to Proxysterr soon.)
Where our IPs come from
One thing doesn't change across tiers: every IP in the Proxysterr pool is ethically sourced — from real people who genuinely consented to share their connection. No hijacked devices, no shady SDKs. Clean sourcing is part of why the IPs stay trusted.
Which one should you use?
Quick guide: datacenter for speed on easy targets; residential as the trusted all-rounder (from $1/GB); mobile for the hardest social / app targets that block everything else; premium residential when you need near-flawless, CAPTCHA-free IPs for serious scraping (from $2/GB). Many users mix tiers by task.
Proxysterr runs residential and mobile pools — ethically sourced, from $1/GB, paid with crypto, no KYC, no expiry — with premium residential launching soon. Sign up and pick the tier your task actually needs.
