Rotating Proxy Same IP Every Request? How to Test It

Why the IP repeats, a curl and a Python test, and how to open a new connection on purpose.

Why the same IP shows up

Rotation in a Proxy302 rotating line happens when a new connection is opened, not on every request. If your client keeps one connection open (HTTP keep-alive) and sends ten requests on it, all ten leave from the same IP. That is expected behaviour, not a fault.

Two other things also keep the IP: a session you started on purpose (the Budget line offers 1 to 120 minutes; the Premium line usually keeps the same IP while in use and changes after about 5–10 minutes idle), and a client library that pools connections for you.

What you will see in each test

What you will see in each test
ItemSetupExpected IPs
Shell loop, one curl process per requestEach run opens a new connectionA new IP each time (no session)
One curl command with several URLscurl tries to reuse the connectionOften the same IP
Python: one requests.SessionThe pool reuses one connectionThe same IP
Python: a new Session per requestA new connection per requestA new IP each time (no session)

Sources: curl manual and Requests documentation (read 12 November 2026) for connection reuse; Proxy302 behaviour from the product facts file (a new IP on each new connection, a reused keep-alive connection keeps its IP).

Test with curl: one process per request

for i in 1 2 3 4 5; do
  curl -s -x http://LOGIN:PASSWORD@HOST:PORT https://ipinfo.io/ip
  echo
done

Example only. Replace LOGIN:PASSWORD@HOST:PORT with a rotating residential line (HTTP uses port 2222). Each pass starts a new curl process, so each opens a new connection.

Test with Python requests: one Session or a new one

import requests

proxy = "http://LOGIN:PASSWORD@HOST:PORT"
proxies = {"http": proxy, "https": proxy}
url = "https://ipinfo.io/ip"

# A: one Session, the pool reuses a connection
with requests.Session() as s:
    print("one session:", [s.get(url, proxies=proxies, timeout=20).text.strip() for _ in range(5)])

# B: a new Session per request, so a new connection each time
ips = []
for _ in range(5):
    with requests.Session() as s:
        ips.append(s.get(url, proxies=proxies, timeout=20).text.strip())
print("new session each time:", ips)

Example only. For SOCKS5 install requests[socks] and use socks5h://LOGIN:PASSWORD@HOST:PORT (port 3333).

Still the same IP: check in this order

A: same IP in a single Session

Check Connection reuse, which is normal.

Fix Use the new-Session-per-request version, or close the session between calls.

Stop when If B shows different IPs, rotation works and nothing needs fixing.

B: still one IP

Check The credential may carry a session setting (1 to 120 minutes on the Budget line), or you are on a static line.

Fix Generate a connection without a session, or confirm in My assets that this is a rotating line, then run B again.

Stop when A leased static IP never rotates during its term; that is by design.

Errors instead of IPs

Check Protocol and port: HTTP uses 2222 and SOCKS5 uses 3333; a credential generated as HTTP fails over SOCKS5.

Fix Generate a new credential as SOCKS5 if you need SOCKS5, then retest.

Stop when Two failures with correct values: send the order number to Support.

Choosing a line for rotation

Rotating residential traffic is sold per GB: the Budget line from US$1.50 per GB and the Premium line from US$5 per GB, with larger packages cheaper per GB. Both change IP per new connection unless you start a session. There is no free trial; the smallest purchase is 1 GB.

FAQ

Does a rotating proxy change IP on every request?

No. At Proxy302 the IP changes on each new connection. Requests sent over one reused connection share an IP.

How do I force a new IP in Python?

Open a new connection: create a new requests.Session for each request, or close the session between calls.

Why does curl show the same IP for several URLs?

curl tries to reuse connections within one command line, but not between separate curl runs. Run curl once per URL to get separate connections.

Does the number of concurrent connections matter?

Dynamic lines do not limit concurrent connections; each new connection gets its own IP unless a session is set.

    Read on 12 November 2026: a Session uses urllib3 connection pooling so requests to the same host reuse the underlying TCP connection; "keep-alive is 100% automatic within a session"; connections return to the pool only after all body data is read; proxies are set with the proxies argument; SOCKS needs requests[socks] and socks5h resolves DNS on the proxy.
