What Is an ISP Proxy? (Static Residential, Priced and Dated)

An ISP proxy is a static IP address that is registered to a real internet service provider but served from a datacenter. Targets see an ISP-registered address — the kind a real household or business has — while the connection itself runs at datacenter speed and reliability. Vendors also sell the same product as “static residential.” It costs per IP rather than per GB, which changes the math completely.

What an ISP proxy is, in plain English

Every IP address is allocated to someone. The split that matters:

• Datacenter IP — allocated to a hosting company, lives in a rack. Fast, cheap, instantly recognizable as a server.
• Residential IP — allocated to a real subscriber by an ISP, lives on a home or mobile connection. Looks human, but the connection is a home line.
• ISP proxy — an IP allocated to a real ISP (so it carries residential reputation) that the proxy company has arranged to host in a datacenter (so the connection is fast and stable).

That is the whole product: residential reputation, datacenter plumbing. You rent the address itself, not gigabytes of rotation.

How it differs from rotating residential

The pricing tells the story. Residential is sold per GB because the value is in the rotation — thousands of addresses, each used briefly. ISP proxies are sold per IP because the value is in the constancy — one address you hold for weeks or months.

The 2026-09-19 rates in that table come from our dataset: residential entries ran IPRoyal $1.75/GB to Oxylabs $6.00/GB; per-IP ISP pricing ran Webshare $0.30/proxy to Rayobyte $5.00/IP.

What it costs — September 2026

All figures read from vendor pages on 2026-09-19.

Read 2026-09-19. Per-IP rates are monthly; “from” figures are as printed by the vendor. Rayobyte’s USA rate is the 5–99 IP tier; other countries differ.

Why per-IP pricing hides volume

An ISP proxy at $1.80/IP looks cheaper than residential at $1.75/GB — until you realize you are comparing an address to a gigabyte. The real question is how much traffic each of your IPs carries. A checkout flow moving a few hundred MB per month per IP is cheap on per-IP pricing; a scraper moving 50 GB through one address is not, because one IP will get blocked long before 50 GB anyway.

Rule of thumb from the data: if the job needs one address and light traffic, per-IP wins. If the job needs volume, buy rotating residential and let the pool carry it.

Who sells them, and the naming trap

Every provider in the table sells the same physical product under a different label:

• Webshare: static residential — $0.30/proxy at 20 IPs (2026-09-19)
• Rayobyte: ISP static — $5.00/IP USA, plus an ISP rotating pool from $3.75/GB
• Bright Data: ISP — from $1.30/IP on its residential pricing page
• IPRoyal: ISP — from $1.80/proxy, 500K+ unique IPs published
• Oxylabs: ISP proxies — from $16/GB, sold by traffic

When you compare quotes, normalize the unit first. A $1.80/proxy quote and a $16/GB quote are not the same product shape.

Use cases where ISP proxies are the right tool

• Account operations — a static ISP-registered address per account, held for the account’s lifetime.
• Checkout and sneaker/ticket flows — the target expects a consistent visitor; rotation triggers risk checks.
• Ad verification and brand protection — you need to see what a real regional customer sees, repeatedly, from the same place.
• Any long-lived session — the address stays, so cookies and session state survive.

The flip side, honestly: ISP proxies do not spread load, they concentrate identity. If your job is anonymous volume, this is the wrong product — that is what rotating residential and datacenter are for.
