Check for a change of IP when a site refuses a CAPTCHA token. Some flows compare the address behind the original page request with the one behind the submission, so an otherwise usable result may fail that check.

Image recognition presents a different situation. The service receives the image itself. That operation does not necessarily need any proxy details.

Before comparing proxies for CaptchaAI, follow the requests through your application. Group the website requests that have to share an address, and allow that address to stay in place until the group is complete. This gives you a basis for choosing a rotation interval.

A proxy and CaptchaAI have different jobs. Routing a request through a proxy gives the website that proxy's external IP. CaptchaAI's response may contain recognized text or a token that the application passes on to the site, depending on the task.

The official Normal Captcha example uploads an image with no proxy parameters. Regional website testing could still require the browser to use a proxy while it fetches the image and submits the answer. The image recognition step does not automatically inherit that requirement.

For a browser-based challenge that checks IP matching, CaptchaAI may also need to visit the website through your chosen proxy. Pass the proxy details with that task when the method requires them. Your browser settings are local; CaptchaAI needs its own task parameters for that route.

CaptchaAI's proxy guide says that proxy use is disabled by default. Contact support to have it enabled on your account and confirm your CAPTCHA type at the same time. For a CaptchaAI proxy setup, use the documentation for that method: another method's proxy and proxytype example may not apply.

For a flow with an IP match requirement, keep the address unchanged from the first step to the last:

Page request → CaptchaAI solve → token sent to the website.

With rotation enabled, a page request can leave through one IP and the solving or submission request through another. The website then sees different addresses for actions it expects to belong together. That mismatch may cause the result to be rejected.

In that situation, configure the same exit IP for requests to the target website throughout the sequence. This applies to the browser's route and the proxy CaptchaAI uses when solving. Calls that submit or poll an API task have a separate role; they do not all need to use that exit IP merely because the website requests do.

Alt: A workflow requiring IP matching: browser and CaptchaAI solver requests use the same exit IP for page loading, solving, and token submission.

Keeping the IP consistent also does not replace other integration requirements. CaptchaFox is one example: its guide tells you to submit the result through the same proxy and use the User-Agent supplied in CaptchaAI's response. User-Agent carries the browser description in an HTTP request. A consistent IP alone will not fix mismatches in other required parameters.

If a browser profile needs the same address for a long session or across repeated visits, Static ISP proxies are one option. They give the profile a fixed IP from an internet provider's network.

In a QA check of a form that requires one IP, treat opening the page, handling the CAPTCHA, sending the form, and checking its response as one session. Keep the address assigned until that sequence ends.

MangoProxy keeps a Static ISP address assigned throughout the paid rental period, with no automatic rotation. You can leave that address assigned to the workflow instead of adjusting a timer to fit each run. HTTP and SOCKS5 are available; the protocol still has to be supported by your client and the CaptchaAI method.

A repeat run can use the same network address. It remains possible for the site to reject the token or request further verification; a permanent IP removes an address change from the test, but cannot ensure that the answer is accepted.

A task may call for an address from a user network, or for separate checks from several regions. Those are reasons to look at residential proxies. When selecting the GEO, you choose the exit country; some products also let you select a more specific location.

For example, a regional form test can run from one country through to completion. A later, separate run can use another IP or GEO. Within a run that needs a consistent address, wait until the operation ends before changing it.

A sticky proxy session gives a test temporary use of one address from the pool. Before relying on it, establish when it ends, how renewal works, and what the provider does if that node becomes unavailable. The duration has to allow for waiting and retries as well as the requests your script sends.

Using the same host and port twice with rotating proxies can still produce two different exit addresses. Where a provider uses a sticky session identifier, carry it through the related browser and CaptchaAI settings. Also check that the provider's session mode can keep both clients on the same exit address.

Rotation can be useful between independent tasks. Frequent IP changes within one connected sequence may conflict with its requirements.

Datacenter proxies use addresses from data centers. A workload that accepts these addresses is worth testing with a datacenter option. Use a representative batch of independent tasks to compare response times, connection availability, and cost before increasing the volume.

Static datacenter proxies can keep an address in place too. You may find that a fixed datacenter IP meets the task's requirements without needing an address from an ISP network.

Before scaling, run several tests through to the website's response after result submission. Stopping at a loaded page would leave you without evidence that the solve and submission work over that connection.

Choose a mobile proxy when the test calls for a mobile carrier's IP. Testing a site's response to a carrier connection is one example.

The browser can be mobile without the connection using a mobile carrier IP. Decide whether the test actually needs that IP type, then look at the available GEOs and the rules for changing the address. IP origin and rotation mode are separate characteristics.

There is no basis for choosing a mobile proxy solely in the hope of improving the outcome for every CAPTCHA.

The IP's network might be residential, ISP, datacenter, or mobile. The session mode describes how it stays in place or changes. Both matter when choosing a proxy.

The chosen method determines whether CaptchaAI needs a proxy for CAPTCHA solving. Check its requirements alongside the browser's route to the website. If only the browser needs a proxy, there is no reason to copy those settings into the solver task.

For the form example, the final action could be receiving the submission response. A requirement to keep one IP would therefore extend from the initial page request through to that response. Independent tasks can still run in parallel. Give them separate session configurations where needed to keep one task's rotation from affecting another.

Start with the country you need to connect from. Then check for any requirement to use a residential, ISP, datacenter, or mobile address. Static ISP can serve a task that repeatedly needs the same ISP IP. For regional tests that temporarily need one address, consider a residential pool with sticky sessions. Test a datacenter option too if server IPs are acceptable.

You can choose from these types within MangoProxy, assigning each task a connection with the location and session behavior it needs. A project can use several types when its tasks have different requirements.

For an operation that must keep its IP, compare a static address with the available sticky session duration. If addresses need to change between independent operations, schedule rotation at those boundaries. The frequency of IP changes should follow the sequence of actions.

The protocol has to work with both the proxy service and your client. The options listed by CaptchaAI are HTTP, HTTPS, SOCKS4, and SOCKS5. With username/password authentication, its guide puts login:password@IP:PORT in proxy. Put the protocol in the separate proxytype parameter.

An application may expect a different field order from the string in your dashboard, or individual fields for the credentials. Check the expected format first. With IP allowlisting, allowing only your computer's IP may not be enough, because the remote solving service also connects to the proxy. Confirm how to allow that connection with CaptchaAI and your proxy provider.

Check the IP and GEO in the application that will run the job. Continue there with a page request, a CaptchaAI task, and submission of the returned answer. Where one IP is required, verify that the same address is retained throughout the test.

Keep the task ID with each failure and note the last step reached. You can then investigate the connection, the solve, or the website's response without treating them as the same error. Exclude proxy passwords and API keys from the log. Loading an ordinary page successfully leaves the rest of the flow to be tested.

Alt: Static ISP, residential, datacenter, and mobile proxy use cases, with static, sticky, and rotating session modes shown separately.

Rotating between page load and submission. For a connected sequence, check rotation settings in every client that accesses the website.

Forgetting the waiting time. The sticky session has to last through the wait for a solution and any retries, as well as the active steps.

Choosing by the type label alone. Residential does not replace an address retention setting, while static does not identify the network origin without further details, such as ISP or datacenter.

Using incorrect credentials. Verify the address, port, username, and password in the order the receiving API or application expects.

Selecting the wrong protocol. Check the selected protocol at both ends of the connection. HTTPS in the website's URL does not itself determine the proxytype value.

Relying only on an external checker. Repeat the connection check in the working client, then test the target workflow through to the end.

The country cannot substitute for an exact IP match when the workflow requires one. Use the actual IP values to check the match.

Choose session settings that cover the operation's full duration, or select a static address. After an IP change, follow the target workflow's rules for continuing. You cannot assume that the previous session context will still be accepted.

Look at the entire path from the page request to the submitted answer when choosing a proxy for CaptchaAI. First check whether the solving service needs a proxy, then whether the IP must remain consistent across related stages.

For workflows that need a fixed address, consider Static ISP or static proxies from another suitable network type. A suitable sticky session may work for a time-limited operation. Use rotation where tasks are independent and IP changes fit their logic. Make the final choice after testing the full operation in your client.
