An ISP proxy (also called a static residential proxy) is an IP address registered to a real consumer ISP — Comcast, AT&T, Deutsche Telekom — but hosted on datacenter-grade servers rather than an actual household device, so it carries residential-network trust with datacenter speed and a fixed, non-rotating address.
A datacenter proxy's IP belongs to a hosting provider — AWS, Hetzner, OVH — and sites flag that ASN by default since real consumers don't browse from cloud ranges. A residential proxy's IP belongs to an actual home device, routed through a consent-based network, which is why it's slower, less predictable, and priced per GB. An ISP proxy buys IP blocks directly from a consumer ISP and hosts them on stable servers: the ASN reads as residential to any site that checks it, but the underlying infrastructure behaves like a datacenter connection — fast, always-on, and billed per IP rather than per GB of household bandwidth.
That combination makes ISP proxies the odd one out on the trust ladder: they inherit a residential ASN's reputation without inheriting a residential connection's instability, at a price closer to datacenter than true residential.
The defining feature is that the IP doesn't rotate — you keep the same address across a session, a day, or longer, depending on the plan. That's exactly what account-based work needs: a social-media management tool, a sneaker or ticketing account warmed up over weeks, or any login flow where a site treats a sudden IP change as a red flag worth a security review. Rotating residential or datacenter pools solve a different problem — spreading volume across many identities — which is why the two are complementary, not substitutes.
The tradeoff is supply and scale: ISP proxy pools are far smaller than residential networks built from millions of consumer devices, and heavy anti-bot systems that fingerprint beyond the ASN (TLS, browser behavior, request pacing) don't treat an ISP IP as automatically trustworthy. It solves the IP-reputation layer, not detection as a whole.
How Crawlora handles this
Crawlora's proxy tiering routes by what a target actually checks rather than a single IP type — for identity-sensitive, session-based work an ISP-style static IP is the right tool, and for high-volume anti-bot-hardened targets rotating residential or datacenter pools take over, all selected and billed through the same API without you managing separate proxy contracts.

FAQ
No — a residential proxy routes through a real household device, while an ISP proxy is a datacenter-hosted IP that's registered to, and inherits the reputation of, a consumer ISP. It looks residential to an ASN check but behaves like a stable datacenter connection.
When a target penalizes IP changes more than it penalizes a datacenter-adjacent ASN — account management, social platforms, or any login-based session where consistency matters more than blending into a large rotating pool.
No — they solve IP reputation, not fingerprinting or behavioral detection. A hardened anti-bot system still checks TLS fingerprints, browser signals, and request pacing regardless of how trustworthy the IP's ASN looks.
