A website normally never sees your IP when you go through an anonymous proxy. It sees the exit IP, looks up which network owns that address block, and decides how much to trust the request. That lookup is the real difference between datacenter and residential proxies. A datacenter exit belongs to a hosting company, a residential exit belongs to a consumer ISP, and bot filters treat them very differently.
This guide compares datacenter vs residential proxies on speed, cost, block rates and IP reputation. It also shows how to check which kind of proxy you are actually getting. For scraping protected sites, ad checks by region or localized prices, residential proxies are usually what the job needs. Datacenter proxies win on throughput and price everywhere else. We ran every lookup and block probe below in November 2026 from a Rocky Linux 9 server at Hetzner and a home line on Safaricom in Nairobi.
Pick the proxy type for the job
Start from the target, not the price list. If the site you’re hitting does not run serious bot protection, a datacenter proxy is faster and costs a fraction as much, so there is no reason to pay per gigabyte. If the site scores visitors by IP reputation, or you need to look like a normal user in one city, you need an exit IP owned by a home ISP:
- Public APIs, your own sites, uptime checks, bulk downloads: datacenter
- SEO rank tracking and SERP collection at volume: residential, rotating
- E-commerce price and stock monitoring on large retailers: residential
- Ad verification and geo-targeted content checks: residential with city targeting
- Logged-in sessions that must keep one IP for hours: ISP (static residential) or a private datacenter IP
Most teams we work with end up running both. Bulk traffic goes through cheap datacenter IPs, and only the targets that block them get a residential pool, which keeps the per-gigabyte bill small.
Compare datacenter vs residential proxies
The table puts the two side by side. The rows that matter most in practice are who owns the IP block and how you’re billed, because almost every other difference follows from those two:
| Property | Datacenter proxy | Residential proxy |
|---|---|---|
| Where the exit IP lives | Server in a hosting or cloud network | Device on a home broadband line |
| ASN the target sees | Hosting provider (AS24940 Hetzner in our test) | Consumer ISP (AS37061 Safaricom in our test) |
ip-api hosting flag | true | false |
| Speed and latency | Fast, gigabit uplinks, stable latency | Slower, depends on the peer’s home link |
| Uptime of one IP | Stays up as long as the server does | Peer can go offline at any time |
| Typical billing | Per IP per month, often unmetered traffic | Per GB of traffic |
| Blocks on protected sites | Common, whole ranges get flagged | Rare on IP reputation checks, but client fingerprinting still applies |
| IP control | Static, you keep the same IP | Rotating per request or sticky for a session |
| Sourcing risk | Low, the provider owns or leases the servers | Depends on how the provider recruits peers |
Reliability is different between the two, but not in the way people expect. A datacenter IP is more reliable as infrastructure because it stays online and keeps its address. It is less reliable as a way in, because targets block it more often. A residential IP is the reverse: requests get through more often, but the individual exit can vanish mid-session when someone switches off their router.
How datacenter proxies work
A datacenter proxy is a proxy server (Squid, 3proxy or a provider’s own daemon) on a VPS or dedicated server whose IPs belong to a hosting company. The provider buys or leases IP blocks, binds them to servers with fast uplinks, and sells access to individual addresses or subnets. The IP whois and the ASN both point at that company, so any site that checks them knows the visitor is not on a home connection.
Providers sell datacenter IPs in three ways, and the difference matters more than the label suggests:
- Private (dedicated) datacenter proxies: one customer per IP
- Shared datacenter proxies: the same IP sold to several customers
- Public or free proxies: open relays anyone can use
Private datacenter proxies are the ones worth paying for, because the IP’s reputation is yours alone and nobody else’s scraping run gets it banned. Shared IPs are cheaper, but you inherit whatever the other tenants did with them. Public proxies are a security problem rather than a product: you do not know who runs them, and they can read or modify anything that isn’t encrypted. If all you need is a fixed egress IP for your own servers, run Squid on a cheap VPS. That is a private datacenter proxy for the price of the VM.
How residential proxies work
A residential proxy routes your request through a real device on a home broadband line, so the exit IP belongs to the subscriber’s ISP. You do not connect to that device directly. You log in to the provider’s gateway, the gateway picks a peer from its pool and tunnels your request to it, and the peer makes the final request to the target. Parameters in the username usually select the country, city or ASN and whether the IP should rotate on every request or stay sticky for a set number of minutes.
The diagram shows why the two behave so differently on the same target. Your client and its real IP are hidden either way, so what the website judges is the exit hop: a server in a hosting ASN, or a home device in an ISP ASN. Bot filters give the second one far more benefit of the doubt, because blocking it risks blocking a paying customer.
Where those home devices come from is the part buyers should ask about. Reputable networks recruit peers through apps and SDKs that pay or reward users for sharing bandwidth with consent, but not every network works that way. In January 2026 Google’s threat intelligence team disrupted IPIDEA, which it called one of the largest residential proxy networks. Google found devices enrolled through bundled SDKs, free VPN apps and trojanized Windows binaries, and over 550 threat groups used its exits in a single week. The FBI has warned about the same pattern several times: hijacked end-of-life routers in May 2025, the BADBOX 2.0 botnet of pre-infected TV boxes a month later, and again in March 2026, when it told businesses to block IPs tied to residential proxy networks.
That second warning matters for you as a buyer. Exits from a badly sourced pool end up on the same block lists as malware traffic, so the clean reputation you’re paying for disappears. Ask a provider how it recruits peers and whether users opt in, and treat a vague answer as a reason to test its pool harder before you commit.
ISP proxies sit between the two. The servers live in a datacenter, so you get datacenter speed and a static IP. The address space is registered to a consumer ISP, though, so most lookups classify it as residential. They are the usual answer when you need a residential-looking IP that doesn’t change for days, such as a logged-in account session.
Check if a proxy is datacenter or residential
You can verify what a provider sold you in under a minute, because the same public lookups bot filters use are free to query. Ask an IP intelligence API which network the exit belongs to, then confirm the owner with an ASN lookup. Run the check through the proxy so the API sees the exit IP rather than yours. Set the proxy URL once:
export PROXY="socks5h://user:[email protected]:1080"If the password contains @, : or /, percent-encode it in that URL. Then query ip-api.com through the proxy (install jq from your distro’s repos, or drop the pipe to read raw JSON). The hosting field is the one to read, and as tells you who owns the block:
curl -s -x "$PROXY" "http://ip-api.com/json/?fields=status,country,isp,org,as,asname,mobile,proxy,hosting,query" | jq .From the Hetzner server, the API flagged the exit as hosting and named the provider’s ASN. The address below is a documentation IP standing in for the real one:
The same query from the home connection came back with hosting false and the ISP’s own ASN, which is exactly what a residential exit should return:
{"status":"success","country":"Kenya","isp":"Safaricom Limited","org":"Safaricom Limited","as":"AS37061 Safaricom Limited","asname":"Safaricom","mobile":false,"proxy":false,"hosting":false,"query":"198.51.100.24"}To confirm who holds an ASN without trusting a single API, ask Team Cymru’s whois service. It answers by ASN as well as by IP, and the AS name makes a hosting company obvious:
whois -h whois.cymru.com " -v AS37061"The home line’s ASN resolves to the ISP, registered with AFRINIC in Kenya:
AS | CC | Registry | Allocated | AS Name
37061 | KE | afrinic | 2008-10-17 | Safaricom Limited - Safaricom Limited, KEA “residential” proxy that comes back with hosting: true, or with an AS name like a cloud or VPS company, is a datacenter IP sold under the wrong label. Run the check against a handful of exits from the pool, not just one, because a rotating gateway hands out a different IP on every request. Keep it to a handful: the free ip-api endpoint allows 45 requests a minute and is for non-commercial use, and Team Cymru null-routes clients that fire large numbers of single whois queries. Notice also that proxy was false on both lines: that flag only catches known proxy and VPN exits, so it’s the ASN and the hosting flag that separate the two types. The SOCKS5 proxy test checklist covers DNS leaks and authentication on the same connection.
See what the IP type changes on real sites
To see how much the exit IP decides on its own, we sent identical curl requests with a browser user agent to three well-known sites from both connections. Each Amazon cell counts 13 requests from two runs a minute apart, all with the same Chrome user agent and most with an Accept-Language header as well. Reddit and Google got one to three probes from each side, with the same answer every time:
| Target | Datacenter IP (AS24940) | Home IP (AS37061) |
|---|---|---|
| Amazon product page | 3 captcha pages, 10 full pages | 13 full pages |
| Reddit JSON API | 403 “blocked by network security” | 403 “blocked by network security” |
| Google search | 200 with a JavaScript challenge page | 200 with a JavaScript challenge page |
Only Amazon treated the two IPs differently, and even there the datacenter IP was blocked in a burst rather than every time: three captcha pages in a row, then ten clean responses a minute later, five of them with exactly the same headers that drew the captchas. Reddit and Google rejected plain curl from the home line too. Something other than the IP gave it away. The likely culprit is the client fingerprint: curl’s TLS handshake and headers don’t match the Chrome its user agent claims to be, and bot-management products score exactly that. That’s the part sellers rarely mention: a residential IP fixes the reputation signal, but a script that doesn’t look like a browser still gets caught. Our write-up on how browser fingerprinting works covers the other half, and driving a real Chromium through Playwright or Puppeteer is the usual next step, since its TLS handshake is the browser’s own.
So the honest answer to “are residential proxies more reliable” is that they remove one reason to block you. On targets that only check IP reputation, that’s the reason that matters, and the residential pool pays for itself. On targets that fingerprint the client, you need both a clean IP and a believable client, and no proxy type fixes the second one for you.
Choose a residential or datacenter proxy provider
Residential bandwidth is where the money goes. On the providers’ own pricing pages in November 2026, entry-level residential plans ran from about $3.50 to $7 per GB outside promotions, and only dropped toward $1 to $2.50 per GB on plans of 100 GB to several terabytes. Datacenter and ISP IPs are sold per address instead, often with unmetered traffic. A job that moves terabytes costs far more on residential than on a fixed set of datacenter IPs. These are the providers we checked, listed alphabetically and not ranked:
- Bright Data: residential billed per GB, claims 400M+ residential IPs in 195 countries, and also sells datacenter and ISP IPs priced per IP.
- CyberYozh: rotating residential at $4/GB pay as you go down to $2.50/GB on the 100 GB plan, rotation per request or sticky for 1 to 1440 minutes, and country, region, city, ZIP and ISP targeting over HTTP or SOCKS5. It also sells mobile, ISP and shared or dedicated datacenter proxies.
- Decodo (formerly Smartproxy): residential at $4/GB pay as you go, cheaper on monthly plans, claims 115M+ IPs, with separate ISP and datacenter products.
- IPRoyal: residential traffic that never expires, from $7/GB in small amounts, plus ISP and datacenter proxies priced per proxy.
- Oxylabs: a large residential proxy pool (175M+ IPs claimed) billed per GB, alongside mobile, ISP and dedicated datacenter proxies under one subscription.
- SOAX: one per-GB rate across residential and mobile, with no datacenter or ISP product listed.
- Webshare: the cheapest datacenter entry point we found (100 proxies for $2.99 a month), rotating residential per GB with ASN targeting.
Pool sizes are the vendors’ own claims and nobody audits them, so do not choose on that number. Buy the smallest plan and run the ip-api and ASN checks above against 20 or 30 exits in the countries you need. Then point it at your real target before you commit to a monthly plan. Mobile proxies get their own section in the guide to types of proxy servers, and we cover how teams feed proxy traffic into reporting in the piece on proxies in data analytics.
