Static ISP proxies that stay put.
An ISP proxy is one ISP-registered address, assigned to your order for the whole billing term, on the stability of a server. Use it when changing IP would log you out.
Sold per IP, billed monthly, with a founding rate held for life. How the volume bands work.
How static ISP proxies work
Every IP on the internet belongs to an autonomous system (ASN), and platforms read that ASN before anything else. A datacenter ASN says "server". An ISP ASN says "internet provider".
ISP proxies are ISP-registered addresses hosted on stable infrastructure. The target sees an ISP network; you get an address that does not rotate and does not drop when someone switches off their router.
The address is assigned to your order for the whole billing term. The same IP carries every request, so a logged-in session, a cart or an account history stays attached to one identity.
Where ISP proxies fit
- Managing accounts that are tied to a consistent login location
- Long sessions: seller dashboards, checkout flows, anything with a cookie that breaks on IP change
- Allowlisting: when a partner needs one fixed IP to add to their firewall
- Repeat access to the same target where a stable history helps
Where they do not
- Broad scraping that needs thousands of different IPs. A fixed set of addresses burns out; rotating residential spreads the load.
- Targets that insist on a mobile origin. Use mobile proxies.
- Pure throughput. Datacenter is built for volume.
What you control
- Country
- Chosen at order time from the countries with ISP ranges available.
- Protocol
- HTTP and SOCKS5, both included.
- Authentication
- Username and password.
- Term
- Monthly, or 3 or 12 months billed at the start of the term. No rotation: the address is the product.
ISP proxies pricing
The rate drops at each volume band, and founding members hold a further 5% for the life of the account. Rates for every band go to waitlist members with their invite.
| Volume band | Rate |
|---|---|
| 1 to 25 IPs | Starting rate |
| 26 to 100 IPs | Lower rate |
| 101 to 250 IPs | Lower rate |
| 251 to 500 IPs | Lower rate |
| 501 to 1,000 IPs | Lower rate |
| 1,001+ IPs | Custom - talk to us |
Checkout shows the full amount, card processing included, before you pay. The pricing page has every volume band and the fair-use terms.
Setup in one request
Each IP comes with its own host, port and credentials in the dashboard. Point your client at it directly:
curl -x socks5h://USERNAME:PASSWORD@HOST:PORT https://ipinfo.io/jsonRun it twice, an hour apart. The IP in both responses should be identical; that is the test of a static proxy.
Questions about static ISP proxies
What is an ISP proxy?
A static IP address registered to an internet service provider and hosted on stable servers. The target sees an ISP network, and the address does not rotate, so one identity can hold a session for the whole term.
What is the difference between ISP and residential proxies?
Residential proxies rotate through a large pool of home devices; ISP proxies give you a fixed address. Choose residential for breadth and ISP for a stable identity.
How static is a static ISP proxy?
The IP is assigned to your order for the whole billing term and does not change between requests or days. If an address stops working for your target, write to support.
Is the IP assigned to me for the whole term?
Yes. Each IP you buy is assigned to your order for the whole billing term and billed per IP per month.
Which protocols do ISP proxies support?
HTTP and SOCKS5. Both are included: each IP comes with an HTTP port and a SOCKS5 port.
