Cheap US Rotating Datacenter Proxies: Price and Tests

What sets the price per GB

The cheapest line is not always the cheapest bill. Look at how the traffic is sold (per GB from a balance, or a monthly plan with a cap), how many countries and how deep a pool you actually get in the country you need, and whether failed or retried requests still use up traffic.

Proxy302 bills US$0.40 per GB from the wallet with no prepaid packs, so there is no monthly allowance to waste.

Check a pool-size claim yourself

A pool size on a sales page tells you little about what your account can reach. Sample it: open many separate connections, record each exit IP, wait a moment, then do a second round. The overlap between the rounds gives a rough estimate with the Chapman formula N = (n+1)(K+1)/(k+1) - 1, where n and K are the distinct IPs in each round and k is how many appear in both.

This is a rough estimate, because rotation may not pick IPs evenly. Treat it as a sanity check: Proxy302 measured about 2,300 distinct IPs in rotation on 10 November 2026, and that is why we say thousands, not millions.

Python sampling script

import requests

PROXY = "http://LOGIN:PASSWORD@HOST:PORT"
proxies = {"http": PROXY, "https": PROXY}

def sample(n):
    ips = set()
    for _ in range(n):
        try:
            # requests.get without a Session opens a new connection each time
            r = requests.get("https://ipinfo.io/ip", proxies=proxies, timeout=15)
            ips.add(r.text.strip())
        except requests.RequestException:
            pass
    return ips

a = sample(200)
b = sample(200)
k = len(a & b)
print(len(a), len(b), k)
print(int((len(a) + 1) * (len(b) + 1) / (k + 1) - 1))

Example only. For SOCKS5 install requests[socks] and use a socks5h:// proxy URL.

Measure speed and success on your own target

1. Step 1

   Fetch your target URL directly without a proxy and note the response time and what a good page looks like.

2. Step 2

   Send 100 requests through the proxy at the concurrency you plan to use. There is no concurrent-connection limit on the line. Count the share that returned the real content (not an error or a block page), and note the median and slowest response times.

3. Step 3

   Divide the price per GB by the share of useful traffic: a US$0.40 line where only half the traffic is usable costs about US$0.80 per useful GB. Compare lines on that number.

Protocol and sticky sessions

HTTP and SOCKS5 are both available; choose the one your tool supports and test it against your target. By default each new connection gets a new IP. For a short sequence of related requests you can hold one IP for about 10 minutes; it changes after about 10 minutes or about 60 seconds idle.
