Static IP proxies: what to check

An ISP or datacenter IP keeps one address for its whole term. If it misbehaves, the cause is usually one of four things: the term ended, the client is pointed somewhere else, the shared plan's traffic ran out, or a website has blocked that address.

1. Is it still running?

Open the proxy from Proxies > ISP or Proxies > Datacenter in the side menu. The status should read Active. Expired means the term ended and the address no longer accepts connections; Reactivate may still be offered for a limited time. See Renewing ISP and datacenter IPs.

2. Is your client using this IP?

Ask an IP-echo service through the proxy a few times:

import requests

proxy = "http://USERNAME:PASSWORD@HOST:PORT"
print({requests.get("https://api.ipify.org", proxies={"http": proxy, "https": proxy}, timeout=15).text for _ in range(3)})

One address in the printed set, matching Public IP address on the proxy's Details card, means all is well. A different address means your client is not using the endpoint from that proxy's Connection card; an error instead of an address means the connection itself failed. On proxies that use a username and password, the Test this proxy button on the Health card runs a check from our side as well.

3. Is there traffic left?

Dedicated and premium IPs have no bandwidth cap. A shared IP comes with an allowance, sized when you order; the Capacity card shows Bandwidth used and warns you when it is nearly spent. If it has run out, tell us through Report an issue.

4. Is one site refusing it?

Every request from a static IP looks like one visitor, so keep the rate steady and under what the target tolerates, and spread heavy work over several IPs. A block a website places on the address stays until the website lifts it, because the address does not change by itself.

Still failing

Use Report an issue on the proxy's page, or see A proxy stopped working: tell us from the dashboard. For a site-specific block, include what A site is blocking your proxy: what we need to see asks for.
