Why antidetect browsers need proxies at all
An antidetect browser spoofs the device side of your identity: canvas, WebGL, fonts, timezone, user agent. But platforms correlate accounts primarily by network: IP address, ASN, geolocation consistency. Run ten perfect profiles through one home connection and you've built ten accounts with a common tattoo. The proxy layer is not optional — it's half the disguise.
Which IP type per profile
| Profile type | IP to use | Why |
|---|---|---|
| Valuable, long-lived (ad accounts, seller accounts) | Static ISP — one per profile | Same residential-looking IP every login; no mid-session changes. See our static ISP guide |
| Ban-sensitive social (creation, warming) | Mobile 4G/5G | Carrier IPs shared by thousands of real users — platforms can't block them cheaply |
| Volume/disposable (scraping, checkers) | Rotating residential | Per-GB, thousands of IPs, profiles are expendable |
The classic mistake is inverted economics: putting cheap rotating IPs on valuable accounts (mid-session IP jumps trigger re-verification) and expensive static IPs on disposable scrapers.
Configuring the proxy in each browser
All major antidetect browsers take the same four fields — host, port, username, password — per profile. The flow:
- AdsPower: New profile → Proxy → type SOCKS5 (or HTTP) → paste host:port:user:pass → Check proxy → save. Bulk-import accepts one proxy per line for batch profile creation.
- Dolphin Anty: Profile → Proxy → New proxy → choose protocol, paste credentials → the built-in checker shows IP, country and speed before you save.
- BitBrowser: Profile settings → Proxy → Custom → protocol + credentials → Proxy detection to verify exit IP and geo.
- Hidemium / GoLogin: Same pattern — per-profile proxy section, paste four fields, run the checker.
Two rules regardless of browser: match the profile's timezone and language to the proxy's geo (a New York IP with a Bangkok timezone is a flag on its own), and always run the built-in checker before opening a target site — a dead proxy leaks your real IP on first load in some configurations.
Mistakes that link your accounts
- Reusing one IP across profiles. The whole point of per-profile isolation dies. One static IP = one identity, always.
- Free or public proxy lists. Already blacklisted, shared with abusers, and often logging your credentials. For account work this is self-sabotage.
- Rotating endpoint on a login-bound account. The IP changes mid-session and the platform sees an impossible travel event.
- Geo mismatch. Proxy in Germany, profile timezone in Vietnam, card billing address in the US — each mismatch adds risk score.
- Buying all IPs from one subnet. Sequential IPs from one range look like a farm. Spread across networks and locations.
