Proxy Rotation: When to Rotate, How Often and When Not To (2026)

What are the four ways to rotate? #

How often should you rotate? #

Rules for polite rotation #

1. Throttle. Rotation is not permission to send more requests. Keep the rate the site can tolerate.
2. Read the rules. robots.txt states what site owners ask automated clients to avoid; RFC 9309 notes it is a request and not a form of access authorisation, so also read the site's terms.
3. Back off on 429. The 429 status means too many requests in a given time, and the Retry-After header can say how long to wait. Wait, then continue.
4. Never rotate mid-login. A session that jumps between countries looks wrong.
5. Keep the rest consistent. A new IP with an old time zone and language is a mismatch; see Timezone, language and IP address.

A short Python example #

Round-robin over a list, with a timeout and a back-off. Use it only on sites that allow automated access:

import itertools, time, requests

PROXIES = ["http://user:pass@host1:8000", "http://user:pass@host2:8000"]
pool = itertools.cycle(PROXIES)

def fetch(url, tries=3):
    for _ in range(tries):
        proxy = next(pool)
        try:
            r = requests.get(url, proxies={"http": proxy, "https": proxy}, timeout=15)
            if r.status_code == 429:      # too many requests: wait, then try the next proxy
                time.sleep(5)
                continue
            r.raise_for_status()
            return r
        except requests.RequestException:
            continue                      # try the next proxy
    raise RuntimeError("all attempts failed")

Rotation and browser profiles #

Browser profiles and rotation solve different problems. A profile keeps one identity stable, with its own cookies, settings and proxy, so each account should usually keep one stable IP. Rotation belongs to jobs made of independent requests. See what a browser profile is and proxy types explained.

Rotating mobile IPs #

With a USB modem, "rotating" means reconnecting to the carrier, and many subscribers share carrier addresses (RFC 6888 describes carrier-grade NAT as sharing one IPv4 address among several subscribers), so the next address is the carrier's choice. You can rotate on a timer, on demand, or from a script: see how to turn a 4G USB modem into your own mobile proxy.

Common mistakes #

1. Rotating faster than the site can tolerate.
2. Rotating in the middle of a logged-in session.
3. Rotating the IP but leaving the time zone and language unchanged.
4. Skipping timeouts and retries, so one dead proxy stops the whole job.
5. Assuming a new IP makes a browser look new. It doesn't change the fingerprint.

Where ADSSPEED fits #

Each ADSSPEED profile has its own proxy, so you can give each account one stable IP. If you want rotating mobile IPs, the Dcom page turns USB modems into HTTP and SOCKS5 proxies and rotates them on a timer, on demand or from a link you can call. Use it only for work you are authorised to do, and follow each platform's rules.
