Quickstart

Each IP on an ISP proxy plan has its own username. All usernames on the plan share one password, and every IP connects through isp.shifter.io:443 over HTTP(S) or SOCKS5.

1. Open your plan

   Log in at shifter.io/panel, open My Plans, and select your ISP Proxies plan.

2. Place your IPs

   The plan page shows a location picker. Search by country, state, city, ISP name or ASN, and assign IPs to the city + ISP (ASN) pairs you want. Each location shows live availability. You do not have to place every IP at once: save what you have and come back for the rest. See Placing your IPs.

3. Copy your credentials

   Every placed IP gets a username like us-new_york-new_york-as701-Ksj25. The shared password is shown on the plan page. Use Copy or download the list as a .txt file. Each line is available in either format:

   isp.shifter.io:443:USERNAME:PASSWORD
   USERNAME:PASSWORD@isp.shifter.io:443

4. Send a request

   Fill in USERNAME and PASSWORD from the panel. Host and port are always isp.shifter.io:443, for both HTTP(S) and SOCKS5.

   curl (HTTP)

   curl -x http://USERNAME:PASSWORD@isp.shifter.io:443 \
     http://ip-info.com/json

   curl (SOCKS5)

   curl --socks5-hostname USERNAME:PASSWORD@isp.shifter.io:443 \
     http://ip-info.com/json

   Python

   import requests
   
   proxy = "http://USERNAME:PASSWORD@isp.shifter.io:443"
   # SOCKS5: "socks5h://USERNAME:PASSWORD@isp.shifter.io:443" (pip install requests[socks])
   r = requests.get("http://ip-info.com/json", proxies={"http": proxy, "https": proxy})
   print(r.text)

   Node.js

   import fetch from 'node-fetch';
   import { HttpsProxyAgent } from 'https-proxy-agent';
   
   const agent = new HttpsProxyAgent(
     'http://USERNAME:PASSWORD@isp.shifter.io:443'
   );
   const res = await fetch('http://ip-info.com/json', { agent });
   console.log(await res.text());

5. Check the location

   The response shows the city and ISP you placed that username on. Each proxy keeps its city and ISP for as long as the plan is active. The IP address behind it can refresh over time, like a real home connection.

6. Spread the work across your IPs

   Keep one username per worker, per account, or per target site so each identity stays on its own city and ISP.

Tip

Proxy URL formats for your client: http://USERNAME:PASSWORD@isp.shifter.io:443 or socks5://USERNAME:PASSWORD@isp.shifter.io:443.
