Most teams start with datacenter or residential proxies, and most of the questions a marketing lead or e-commerce manager asks about proxy spend come back to these two. The short answer is that datacenter is quicker and costs less per GB, while residential is accepted by more sites and shows you what local customers see. The useful answer depends on the jobs your team runs, so this article works through them one at a time.
What separates the two
The difference is who owns the IP address. A datacenter IP belongs to a hosting or cloud company and runs on server hardware. A residential IP is one that a home internet provider has assigned to a household; in our pool, those households have opted in to share their connection.
Any website can look up which network an address belongs to. A datacenter address reads as server traffic, a residential one as a person at home. Nearly every practical difference between the two follows from that.
Where datacenter proxies earn their keep
For a lot of routine business work, the site on the other end has no objection to server traffic, and paying more buys nothing extra. Datacenter proxies are the sensible default for:
- QA of your own websites and landing pages from different countries.
- Price and catalogue checks on stores and marketplaces that accept datacenter traffic.
- Uptime and availability checks on public pages.
- Feeding SEO and analytics tools that collect from lenient sources.
- Large, repetitive jobs where speed and cost per GB matter most.
Where residential proxies justify the extra cost
Residential proxies pay for themselves when the result depends on being treated as an ordinary local visitor:
- Local search results. Search engines vary results by location, so rank tracking for a city or country needs an IP from that place.
- Ad verification. To confirm what a customer in a given market is shown, the check should come from a household connection in that market.
- Protected retail sites. Competitor stores and marketplaces with bot management often challenge server IPs, while household connections are usually served as normal.
- Account work. Client social and seller accounts behave more predictably on one residential IP held with a sticky session, always within each platform's terms.
The two types compared
| Question | Datacenter | Residential |
|---|---|---|
| Who owns the IP? | Hosting and cloud companies | Home internet providers, with households opting in |
| How do strict sites treat it? | Often challenged or blocked | Usually served like any home visitor |
| Speed | Quick and steady | Varies with each household connection |
| Cost per GB | Lower | Higher |
| Location targeting | Country level | Country, and city where available |
| Typical first job | QA and volume checks on lenient sites | Local results, ad checks and protected stores |
Cost depends on data used, not only on the rate
Both types are billed per GB, so the figure that decides the invoice is how much data each job consumes. Fetching the HTML of a product page uses a small fraction of what loading the full page, with images and scripts, takes in a headless browser. Two consequences follow:
- A job that fails on datacenter IPs is not cheaper just because the rate is lower. Retries use data too, and gaps in the reports take staff time to fill.
- A job that already works on datacenter IPs gains nothing from residential except a larger bill.

Settle it with a one-week pilot
The quickest way to decide for your team is to test both types on your own targets:
- List the sites and jobs the team runs each week, with the markets each one covers.
- Place a small pay-as-you-go order of each type. There is no subscription to cancel afterwards.
- Run the same jobs through both for a few days. Record successful responses, blocks, CAPTCHAs and the data each job used.
- Assign each target to the type that met your pass mark at the lower cost.
- Set the session mode per job: rotating for collection, sticky for anything signed in. Our session mode guide explains the difference.
Many teams finish a pilot like this with a two-tier setup: datacenter for the bulk of the work and residential for the targets that need it, run as separate orders in the same dashboard. Whichever mix you choose, collect only publicly available data and stay within each site's terms of service.
When neither type is the answer
Two situations call for something else. Mobile-first platforms such as Instagram and TikTok are built around carrier connections, which is what mobile 4G/5G proxies provide. And the strictest sites, or accounts that need one fixed address for the life of an order, are better served by Residential Premium, which includes our static residential (ISP) IPs.
Questions managers ask
Can we run both types on one account? Yes. Each order is independent, so datacenter and residential orders sit side by side in the same dashboard.
Should we buy residential for everything, just to be safe? No. It costs more and responds more slowly, and on sites that accept datacenter traffic it adds cost without improving the data.
Will our existing tools work with both? Yes. Every type supports HTTP, HTTPS and SOCKS5, with sign-in by username and password or by a whitelisted IP.
