> Set up an antidetect browser proxy the right way: one dedicated IP per profile, matching timezone and language, HTTP or SOCKS5, and platform rules.

An antidetect browser proxy setup pairs each browser profile with its own IP address so that separate profiles do not look like one person switching tabs. Agencies use multi-profile browsers to keep client accounts apart; sellers use them to separate a Vietnamese storefront from a US one; QA teams use them to test how a site behaves for users in different countries. The proxy is the part people most often get wrong. This guide covers the generic setup that works in most multi-profile browsers, the consistency checks that matter, and where the platform's own rules draw the line.

## Start with the rules, not the tools

Every major platform publishes rules about how many accounts one person or business may run, whether automation is allowed, and how agencies should access client accounts. Many platforms also offer official tools for exactly this, such as business managers and partner access, which let one team manage many accounts without separate browser identities at all.

Read those rules first and use the official route where one exists. An antidetect browser and a proxy are organisational tools: they keep legitimate, separate accounts tidy and stop sessions from bleeding into each other. They are not a way to evade bans, run accounts a platform has prohibited, or get around verification. No proxy prevents bans, and accounts that break a platform's terms can be closed regardless of how carefully the browser is configured.

## Why one dedicated IP per profile

A browser profile stores cookies, local storage and a device fingerprint. If two profiles share an IP, a platform can reasonably infer that they belong to the same operator, which defeats the purpose of separating them. The cleanest model is simple: one profile, one dedicated IP, for the life of the account.

Dedicated matters here. A shared proxy carries other people's traffic and history. A rotating proxy changes address between sessions, so an account that logged in from one city yesterday appears somewhere else today, which tends to trigger security checks. A dedicated proxy keeps the same IP for the whole term and is assigned to one customer only. The [dedicated proxy guide](https://cloudj.net/blog/dedicated-proxy-guide) explains the trade-offs in detail, and if you are sizing an order, see [how many proxies you need](https://cloudj.net/blog/how-many-proxies-do-i-need).

### Static ISP or static residential

Cloudj offers two dedicated types. Dedicated IPv4 is a static ISP proxy: a static IP registered to an ISP, fast and stable, and offered in all seven proxy countries, subject to stock. Static residential ISP IPs come from home broadband and look like a regular user, but are only available in the [United States](https://cloudj.net/proxy-ipv4/united-states) and [Vietnam](https://cloudj.net/proxy-ipv4/vietnam). For logins to consumer-facing platforms, many teams prefer static residential; for internal tools and QA, dedicated IPv4 is fine. The [datacenter vs static ISP comparison](https://cloudj.net/blog/datacenter-vs-static-isp-proxy) explains how these types differ from generic datacenter proxies.

## Antidetect browser proxy setup, step by step

The menus differ between antidetect browsers, but the fields are almost always the same.

1. **Order one IP per profile.** In the [Cloudj console](https://app.cloudj.net), choose the country and type, set the quantity to the number of profiles, and pick a term of 1, 3, 6 or 12 months. With auto-renew on, the same IPs carry on running, which keeps each account's location stable.
2. **Copy the credentials.** The console shows host, port, username and password for each proxy.
3. **Create the profile and open its proxy settings.** Choose the proxy type (HTTP or SOCKS5) to match the protocol of your order. You can switch the protocol in the console where the location supports it.
4. **Enter host, port, username and password.** Many tools accept a single string in the format `HOST:PORT:USERNAME:PASSWORD`; check which order your tool expects.
5. **Use the built-in proxy check.** Most tools test the connection and display the detected country, city and timezone. Do not save the profile until this shows the right country.
6. **Match timezone, language and geolocation to the IP.** Most tools offer an option to derive these from the proxy. Use it, then confirm the values.
7. **Set WebRTC to follow the proxy** (or disable it if your use case allows), so the browser does not reveal your real IP through WebRTC.
8. **Label the profile and the IP together.** Keep a simple sheet mapping profile name, account and proxy IP. When you have dozens of profiles, this record prevents accidental reuse.

## Consistency checklist by country

A mismatch between IP and browser settings is the most common reason a carefully built profile still looks odd. Use these values as a starting point and always confirm against the proxy check.

| Proxy country | Timezone | Typical language | Static residential available |
|---|---|---|---|
| Vietnam | `Asia/Ho_Chi_Minh` | `vi-VN` | Yes |
| United States | Depends on the IP's city, for example `America/New_York` or `America/Los_Angeles` | `en-US` | Yes |
| Japan | `Asia/Tokyo` | `ja-JP` | No |
| South Korea | `Asia/Seoul` | `ko-KR` | No |
| Singapore | `Asia/Singapore` | `en-SG` | No |
| Hong Kong | `Asia/Hong_Kong` | `zh-HK` or `en-HK` | No |
| United Kingdom | `Europe/London` | `en-GB` | No |

Language is a judgment call: a Vietnamese team managing a US account may reasonably browse in English. What matters most is that timezone and geolocation agree with the IP.

## Troubleshooting a profile that will not connect

- **Proxy check fails immediately**: the proxy type in the profile does not match the protocol of the order, or the host and port were swapped.
- **Authentication error**: the password was rotated in the console and the old one stopped working. Copy the new one.
- **Using an IP whitelist**: if the order uses a whitelist (up to 20 addresses) instead of a password, the computer running the antidetect browser must have its public IP on the list. Office IPs can change, so recheck after a network change.
- **Wrong country shown**: some geolocation databases lag behind; check with two or three IP lookup sites before concluding the IP is wrong.
- **Profile works, platform asks for verification**: a new IP for an existing account often triggers a security check. Complete it honestly and then keep that IP for the account.

## Platform notes

Each platform has its own expectations. Our guides on [TikTok proxies in the US](https://cloudj.net/blog/tiktok-proxy-us), [Facebook Ads proxies](https://cloudj.net/blog/facebook-ads-proxy) and [e-commerce seller proxies in Vietnam](https://cloudj.net/blog/ecommerce-seller-proxy-vietnam) cover platform-specific setup. The common thread is the same: use official business tools where they exist, keep one stable IP per account, and follow the platform's rules.

## FAQ

### Can two profiles share one proxy?

They can technically, but the platform can then link them. If the profiles represent separate accounts, give each its own dedicated IP.

### Should I use HTTP or SOCKS5 in an antidetect browser?

Either works in most tools. Pick the one your tool handles best and set the order to the same protocol in the console.

### Will a static ISP or static residential proxy stop my account from being banned?

No. No proxy prevents bans. A stable, consistent setup reduces avoidable security checks, but accounts are judged on behaviour and the platform's rules.

### What happens to my profiles when the proxy term ends?

If auto-renew is on and the balance covers it, the same proxies keep running. If the order is not renewed, the proxies stop at the end of the term and the profiles lose their connection, so plan renewals for accounts you want to keep.

## Build your profiles on stable IPs

Decide how many profiles you need, order one dedicated IP for each in the [console](https://app.cloudj.net), and keep the mapping written down. All proxy countries are listed on the [proxy overview](https://cloudj.net/proxy-ipv4), and current per-IP prices are on the [pricing page](https://cloudj.net/pricing).
