Residential vs ISP vs datacenter proxies: how they differ and which one to buy

Residential vs ISP vs datacenter proxies comes down to two questions: whose network the IP address belongs to, and whether it stays the same. Residential proxies route through consumer connections and rotate. ISP proxies are static addresses registered to consumer carriers but hosted on servers. Datacenter proxies are static addresses registered to hosting companies. Residential is the hardest to tell apart from a real visitor, datacenter is the fastest and cheapest per request, and ISP sits between them: a consumer network's reputation with a server's stability.

The rest of this guide explains where each type comes from, what targets check, how each is billed, and, just as useful, when each one is the wrong buy.

#Residential vs ISP vs datacenter proxies at a glance

Two rows in that table deserve a warning. "Detection risk" is about the IP layer only, and targets look at much more than your IP. "Speed" has no numbers because the honest answer depends on where you are, where the target is, and which exit you land on. Measure it yourself against your own target; the guide on testing a proxy provider, linked below, has the method.

#How each type is sourced: ASNs explained

Every routable IP address sits in a block announced by an autonomous system, identified by an ASN. Regional registries such as ARIN and RIPE NCC record who holds each block, and IP intelligence vendors classify every ASN by the kind of network it is: consumer ISP, hosting, business, education. A target does not need to know which proxy provider you use. It looks up your address, sees the ASN, and scores you by it.

That lookup is the whole reason three proxy types exist.

#Residential: consumer connections

A residential proxy exits through a household connection: a home broadband line or a consumer device on one. The ASN is a consumer provider such as Comcast (AS7922), so the request looks like it came from somebody's living room, because in network terms it did. Providers build these pools from devices whose owners agreed to share bandwidth, usually through an app or SDK. How a provider recruits and pays those peers differs by vendor, and it is a fair question to ask any of them before you buy.

The cost of that realism is control. You do not choose the device, it may go offline mid-request, and its connection speed is whatever that household has.

#ISP: carrier-registered, server-hosted

An ISP proxy is an address block registered to a consumer carrier but plugged into servers in a data centre. IP databases see the carrier's name, so the address is scored like a residential one, while the hardware behind it is a server with a stable uplink. It stays yours for the term, which is why the same product is also sold as a "static residential proxy". Our explainer on what an ISP proxy is covers carrier naming, dedicated versus shared, and how to verify the ASN yourself.

#Datacenter: hosting ASNs

A datacenter proxy is a server address in a hosting or cloud network: AWS (AS16509), Hetzner (AS24940), OVH (AS16276) and thousands of smaller hosts. Nobody pretends these are homes. They are fast, cheap to run and plentiful, and for many targets that is all you need.

#Detection risk: what targets check

Bot protection scores a request on several layers at once, and the proxy type decides only the first:

1. IP and ASN. Hosting ASNs start with a worse score on protected sites. This is the layer residential and ISP proxies improve.
2. IP history. Addresses seen sending abusive traffic land on reputation lists, whatever their ASN.
3. Request rate per IP and per session. Fifty requests a second from one address looks like a bot on any network.
4. Client fingerprint. TLS handshake, HTTP/2 settings, header order, and in a browser, JavaScript fingerprinting.
5. Behaviour. Cookies, navigation paths, and whether a "visitor" ever loads a stylesheet.

So a residential IP will not rescue a scraper that announces itself with a default library user agent and no pacing. Fix the client first, then pick the proxy type your target's IP layer demands. Our guide to avoiding blocks when web scraping covers the client side.

#Speed and stability

A datacenter or ISP request goes from your client to a server with a proper uplink and out to the target. A residential request goes from your client to the provider's gateway, then to a consumer device, then out over that household's connection. The extra hop and the last mile are where residential latency and variance come from.

Stability follows the same shape. A static ISP or datacenter address is there for the whole term. A residential exit exists only while its device is online, so long-running connections can drop and a "session" on residential is a best effort rather than a guarantee. If your job keeps one connection open for hours, that alone may decide the question.

#Pricing models: per GB vs per IP

The billing unit changes which jobs are cheap.

Residential is billed per GB. You pay for bytes, whichever exit carried them. A job that fetches small JSON responses from thousands of distinct exits is cheap. A job that loads full pages in a headless browser, with images and scripts, burns gigabytes quickly. At ProxyHive residential starts at $5.50/GB and the traffic never expires; our guide to residential proxy pricing, linked below, walks through estimating your monthly GB.

ISP and datacenter are billed per IP for a term. You pay for the address, not the bytes. ProxyHive sells both from one IP, starting at $3.20/IP and falling to $1.50/IP per IP at volume, and a dedicated IP carries unmetered traffic. That makes heavy traffic through a few addresses cheap, and a need for thousands of distinct exits expensive.

A rough rule: if a handful of fixed addresses can do the job, price it per IP; if the job needs a different exit for most requests, price it per GB. The pricing page shows every ladder at the price checkout charges.

#Which proxy type for which job

Every use in that table must also fit the allowed-use policy, which is published before you buy.

#When not to use each type

This is the section vendor comparison pages tend to skip.

#Do not buy residential when

• The target remembers you. Logins, carts and checkouts expect one address. A rotating exit triggers re-authentication and security checks. Our comparison of rotating vs static proxies goes into why.
• You move a lot of bytes per request. Per-GB billing punishes media, full page renders and file downloads.
• You need a specific country at ProxyHive. Residential has no location selection today. Use ISP or datacenter, which are placed by country.
• A partner allowlists your IP. An address that changes cannot be allowlisted.

#Do not buy ISP when

• You need a fresh exit on every request. A few static IPs accumulate history fast on a wide crawl.
• The target accepts datacenter traffic. Then you are paying for reputation you do not need.
• You need a carrier or city the stock does not have that day. ISP inventory is finite, and what the order form offers is what is available now.

#Do not buy datacenter when

• The target scores hosting ASNs harshly. You will pay for it in retries and CAPTCHAs, and the cheap IP stops being cheap.
• You run accounts on a platform that flags server traffic. A consumer ASN is the point of ISP here.

#A four-step way to decide

1. Start with datacenter against your real target. Send a realistic sample of requests with a well-behaved client and record the block rate.
2. If the block rate is high, try one ISP IP. If ISP clears it and a few addresses cover your volume, stop there.
3. If you need many distinct exits, try residential. Measure GB per thousand requests so you can price it honestly.
4. Mix lines where jobs differ. Many teams run ISP for accounts and allowlisted APIs and residential for crawling from the same balance.

ProxyHive sells all three from one account: residential, ISP and datacenter, each ordered from the smallest unit. One datacenter IP and the $10 minimum top-up keep step one cheap, and the 1 GB residential trial covers step three.
