The single most important decision when buying proxies is the type. For most people that comes down to two options: residential or datacenter. They sit at opposite ends of the trade-off between trust and cost, and picking the wrong one is the number-one reason projects get blocked or budgets get blown. Here's how they really compare.
What are residential proxies?
Residential proxies use IP addresses that internet service providers assign to ordinary home users. When you route a request through one, the destination site sees what looks like a genuine person browsing from a real home connection. Because that traffic is indistinguishable from a normal visitor, residential proxies are very hard to block — which is exactly why they're the default for serious data work on protected sites.
What are datacenter proxies?
Datacenter proxies come from servers hosted in data centres rather than homes. They're not tied to an ISP's residential customer, which makes them cheaper to produce and blazingly fast. The catch is that their IP ranges are known to belong to hosting companies, so sophisticated websites can identify and block them more easily.
Side-by-side comparison
| Factor | Residential | Datacenter |
|---|---|---|
| Trust / block resistance | High | Lower |
| Speed | Medium | Very fast |
| Cost | Higher (per GB) | Low (per IP or GB) |
| Pool size | Millions of IPs | Large but identifiable |
| Best for | Protected sites, scraping, ad checks | Volume, testing, simple targets |
When to choose residential
Pick residential when the target actively defends against bots: search engines, large e-commerce sites, travel and ticketing, social platforms, and anything that shows different content by location. The higher cost buys you a dramatically better success rate, which usually works out cheaper than burning through blocked datacenter requests.
When to choose datacenter
Pick datacenter when speed and volume matter more than disguise: hitting your own APIs, scraping sites with light defences, bulk uptime checks, and load testing. At a fraction of the price per request, datacenter proxies are unbeatable where they work.
Don't want to choose? Use both. Send easy traffic through cheap datacenter IPs and fall back to residential when you hit blocks. Cheapest Proxies sells both (plus ISP and mobile) from one dashboard at $0.80/GB.

Two hybrids are worth knowing. ISP (static residential) proxies live in a data centre but are registered to a real ISP, giving you residential trust at datacenter speed with a fixed address — ideal for account work. Mobile proxies use carrier 4G/5G IPs and are the hardest of all to block, but the most expensive. We break all four down on our proxy types section.
The bottom line
Residential wins on trust; datacenter wins on speed and price. Most mature setups blend the two, with ISP or mobile reserved for the most sensitive jobs. Whatever you choose, a provider that offers every type under one roof keeps your options open as your needs change — which is a big reason Cheapest Proxies tops our 2026 ranking.
Pricing compared in detail
Cost is where these two types differ most. Datacenter proxies are often sold per IP per month — sometimes just cents per address — or in cheap bandwidth bundles, because they're inexpensive to produce. Residential proxies are billed per GB of traffic and cost more because real ISP IPs are harder to source. But the headline price can mislead: a cheap datacenter IP that gets blocked on every request is more expensive than a residential IP that succeeds first time. Always compare on cost per successful request, not just the sticker price. In 2026, residential bandwidth ranges from about $0.80–$8/GB; our value pick sits at the bottom of that range.
Speed and performance
Datacenter proxies win raw speed — they sit on fast server connections with very low latency, perfect for bulk requests. Residential proxies route through home connections, so they're a little slower and more variable, but more than fast enough for scraping and account work. If you need both speed and trust, ISP proxies bridge the gap.
Security and detection
Anti-bot systems maintain lists of known datacenter IP ranges, so those proxies are flagged more readily on defended sites. Residential IPs blend in with normal traffic, which is the whole point. Whichever you use, remember a proxy hides your IP but not a sloppy browser fingerprint — match realistic headers and timing to stay under the radar.
Which should beginners start with?
If you're new and unsure, start with rotating residential: it works on the widest range of targets and saves you the frustration of chasing blocks. Add cheap datacenter IPs later for the high-volume, low-risk parts of your workflow. Because our top pick sells both (plus ISP and mobile) from one low-minimum account, you can experiment without committing to a single type up front.
