How Many Accounts per Proxy IP, and How Long to Keep Each IP

Why one account per IP

Every login tells the site which IP it came from. When several accounts keep showing up on the same address, the site can tie them together, next to the other signals it checks: the browser fingerprint, cookies, payment details and how the accounts behave. A proxy takes care of the IP; an antidetect browser such as Multilogin, AdsPower or Dolphin Anty takes care of the fingerprint.

No platform publishes a number of accounts per IP it considers safe, so anyone quoting one is guessing. The only number that can't link accounts through their IP is one.

This is about the same platform. One IP carrying one account on each of several unrelated sites is what an ordinary home connection does. Sites run by the same company, such as Facebook and Instagram or Google and YouTube, count as one platform.

How long to keep each IP

A real person's home IP stays the same for days or weeks, so an account that jumps to a new address every time it logs in looks like it has been taken over. Keep each account on one IP for as long as you work in it, and when it has to change, change it to an IP in the same city, on the same internet provider and with the same device OS.

At ProxyFall the session name in the username decides the IP: -session-acc1-lifetime-1440 keeps one residential IP for up to 24 hours, through restarts, and a new session name gives a new one. Lifetimes run from 1 minute to 24 hours.

When the IP has to change

A sticky residential IP is a real home connection, so it ends when its lifetime is up or, now and then, earlier, when that household goes offline. Then start a new session with the same city, ISP and device OS, so the account keeps looking like it logs in from the same place.

Check the IP before a step that matters, such as a login, a payout or an ad change. Find accurate IPs in the ProxyFall dashboard checks where each sticky IP really is, keeps only the ones in your city, and skips any with a Scamalytics fraud score of 60 or more; strict mode keeps only scores under 20.

When a static ISP proxy fits better

Some accounts should log in from exactly the same address for weeks: a long-lived seller account, an ad account with a payment history, a business profile managed by a team. For those, use a static ISP proxy: a dedicated IP registered to an internet provider, yours alone for a month at a time and renewable with the same address, with unlimited bandwidth and up to 100 connections at a time over HTTP(S) or SOCKS5.

Static ISP IPs are priced per IP per month by country, ISP and quantity, with live prices in your dashboard (free sign-up).

Match the device too

Add the device OS the profile claims: -os-windows, -os-android, -os-mac or -os-ios. The connection a site receives comes from the device behind the IP, and its network traffic can show that device's operating system, so match it to the OS the profile claims. macOS and iOS IPs are scarce, so a Mac or iPhone line may find no IP in a small area; Windows and Android are easy to find everywhere.
