ISP vs Residential Proxies, and How ISP Differs From Datacenter

The main difference is time: an ISP proxy is one fixed IP for days or weeks, while residential proxies give you a pool of IPs for seconds to hours each. Datacenter proxies are in the table because ISP proxies borrow from both types.

The IP is registered to an internet provider, not a hosting company. That is the whole difference: both are usually hosted on servers in data centers, but an ISP proxy's IP belongs to an internet provider's range, while a datacenter proxy's IP belongs to a hosting or cloud company, which IP databases label as hosting. A rule that blocks hosting ranges catches datacenter IPs and not ISP IPs.

Why ISP proxies cost more. In the market, an ISP proxy needs both server space and IP ranges that an internet provider registers as its own, and far fewer such addresses exist than hosting addresses. At ProxyField one ISP IP costs from $2.29 for 30 days against $1.39 for a dedicated datacenter IPv4.

The ISP label is not guaranteed. IP databases classify ranges by their owner, and the range of a small regional provider is sometimes labeled as hosting, which removes the ISP proxy's main advantage. ISP ranges are also tidy blocks of neighboring addresses, so a site that bans a whole subnet can catch many of them at once. Before you rely on the label, look the IP up in an IP database such as ipinfo.io or IP2Location and check the owner and type it reports.

Decision rule: start with datacenter proxies for sites that don't check the IP type, and move to ISP when a target blocks hosting ranges. Neither type guarantees access: sites also weigh request volume, browser fingerprint, cookies and the IP's history.

An ISP proxy is an IP address that belongs to an internet service provider's range but is assigned to you as a proxy for a fixed term. Because the IP is registered to an ISP, IP lookups classify it as an ISP or residential address, not a hosting one, so a rule that blocks datacenter ranges does not catch it by range alone. Because it is static, it does not change between requests, sessions or days.

"ISP proxy", "static residential proxy" and "static ISP proxy" name the same product. Most providers host these IPs on servers in data centers, which is why ISP proxies are fast and stay online around the clock while still looking like ISP customers. ProxyField sells them as dedicated ISP proxies: ISP proxies (static residential). ProxyField's ISP IPs are registered to consumer ISPs and run on server connections.

A residential proxy gives you access to a pool of IPs on home connections, through one gateway. You do not rent a particular IP; you ask the gateway for an IP that matches your country, region or city, and it picks one. At ProxyField, the gateway gate.proxyfield.io:7000 gives you a new IP on every request or keeps one IP for a sticky session from 30 s to 36 h, and you pay for traffic, not for IPs.

That model is what makes residential proxies strong for scraping: thousands of requests spread over thousands of IPs, each carrying little traffic. It is also why they are weaker for long sessions: a pool IP is never yours. At ProxyField a sticky IP ends at the first of three events: the ttl you set runs out (30 s to 36 h, 20 min if you set none), the session sits idle for 120 s, or the exit node drops. In the last case the gateway retries once with a new session, so the IP may change, and a broken connection is not restored: your client reconnects.

For anything that should look like one person staying signed in, the length of the session decides.

How to choose for a long session:

1. Write down how long the account or tool must keep one IP, and how long it may sit idle.
2. Longer than a day, or idle for more than 2 minutes at a time: rent a dedicated ISP IP (from $2.29 per IP for 30 days, renewed by you in the dashboard).
3. Otherwise, set ttl to the task length in seconds, up to 129,600 (36 h): <login>-country-us-session-acct01-ttl-3600 holds one US IP for an hour.
4. Keep one session ID per account, and sign in again if a connection breaks.

Managing your own or your clients' accounts this way is allowed; creating fake accounts is not. Social media and marketplace accounts, ad accounts and allowlisted dashboards expect the same IP every time, and an IP that changes mid-session can trigger security checks.

In the market, ISP proxies are usually faster and more stable than rotating residential proxies, because the IP is typically hosted on a server with a steady uplink rather than a home line. They are also built to stay online: a home connection can go offline at any time, while an ISP IP is meant to be there for the whole term.

The trade-off is reputation risk. All your traffic on an ISP IP carries one address, so heavy scraping through it can get that IP flagged. A rotating pool spreads that risk across many IPs.

Detection is the other limit. An ISP IP passes a check that only reads who owns the IP, but a site can also compare the owner's type with how precisely the IP geolocates, or keep lists of subnets known to carry ISP proxies, and flag it where a real home IP passes (can websites detect proxies?). So test the target before you rent: the Easy Trial (1 GB for $2.95) shows how it treats home IPs, and one ISP IP for 30 days (from $2.29) shows how it treats a static one.

ISP proxies are priced per IP for a term; residential proxies per GB of traffic. Which costs less depends on how much traffic each identity uses.

One account that uses 1 GB a month costs from $2.29 a month on one ISP IP or $2.95 for the GB on residential traffic, which never expires. A scraper that moves 100 GB a month across thousands of pages is a residential job: one ISP IP would carry every request, while a rotating pool spreads them over many IPs. ISP terms are renewed by you in the dashboard; nothing renews automatically. See residential and mobile proxy pricing for the full residential ladder.

If a target blocks your first choice, move one step: datacenter blocked, try an ISP IP; ISP flagged, try rotating residential; a target that treats carrier IPs differently, try mobile proxies ($3.45/GB for 1 GB down to $2.45/GB).

If you are not sure, start with residential proxies: the Easy Trial (1 GB for $2.95) runs on the same pool as a 1 TB order, so a test shows how a target treats home IPs. For the static side of the decision, see static vs rotating proxies.
