Anti-detect browsers isolate fingerprints — but IP reputation still drives captcha rate. Picking wrong proxy class (rotating DC on Meta login) wastes perfect Canvas spoofing. This guide maps proxy types to Multilogin workflows and cloud phone mobile stacks.
Proxy classes
| Type | IP source | Best for | Avoid when |
|---|---|---|---|
| Datacenter (DC) | Hosting ASN | Internal tools, low-friction B2B APIs | Facebook, Cloudflare-heavy consumer sites |
| Residential | Home ISP pools | Scraping, SaaS login, general Multilogin | Need long sticky sessions without provider support |
| ISP / static resi | Dedicated ISP lease | High-value ad accounts, long-lived profiles | Budget one-off tests |
| Mobile (4G/5G) | Carrier NAT | TikTok/IG app via cloud phone, strict platforms | Desktop-only web dashboards (overkill cost) |
Sticky vs rotating
- Sticky session — one exit IP for hours/days; required for logged-in ad accounts and warmed profiles
- Rotating — new IP per request or interval; OK for anonymous scraping, bad for session cookies
- Rule — 1 production Multilogin profile : 1 sticky proxy endpoint; never share sticky IP across unrelated account types
Alignment checklist
Full steps: proxy alignment guide. Minimum: IP country = timezone = Accept-Language = WebRTC policy.
By workflow
| Workflow | Recommended |
|---|---|
| Meta / Facebook ads | Sticky residential or ISP, billing country |
| Cloudflare scraping | Residential rotate or ISP; tune TLS separately |
| TikTok app | Mobile proxy on cloud phone layer |
| Agency 100+ profiles | ISP leases + subnet monitoring — scaling |
Pre-flight test (Python)
import httpx
def check_proxy(proxy_url: str) -> dict:
with httpx.Client(proxy=proxy_url, timeout=20) as c:
r = c.get("https://ipinfo.io/json")
r.raise_for_status()
return r.json() # verify country, org ASN before MLX launch
