How Many IPs You See in Two Hours on a Mobile Proxy

People ask how big our IP pool is, and the honest answer is that it is not ours. Every address your line uses comes from the carrier's regional pool for the city your SIM lives in, and the carrier decides how large that pool is and how it hands addresses out. What we control is the rotation: how often your line asks for a new address, which on an hourly line is as often as you like. This article sets out what that means in practice for a two-hour session, and when you want many addresses versus one that stays put.

Where the addresses come from

Your line is a SIM from AT&T, T-Mobile or Verizon in a modem in one of our eight cities. When the modem registers on the network, the carrier assigns it a public address from the pool it uses for that metro. Those pools are large, since they serve every subscriber in the area, and they are shared, since many phones sit behind each address. When the modem disconnects and reconnects, the carrier usually assigns a different address from the same pool, though it is free to hand back the same one.

This is why we say the pool is the carrier's. We do not own a block of addresses and we cannot add to it, reserve part of it or promise that a given address will never come back. What we own is the SIM and the modem, and the right to reconnect them whenever you ask.

Rotation on demand

Every line comes with a rotation link. Open it, call it from a script, press Rotate in the dashboard or the Telegram bot, or set a timer in the dashboard, and the modem drops its session and re-registers. The whole cycle takes a few seconds to a little under a minute depending on the modem and the carrier, and there is no imposed pause between rotations and no count against you. Sticky addresses are the default: if you never rotate, the carrier keeps the address for as long as it keeps the session, which is often many hours.

The rotation link works the same on a two-hour line as on a monthly one. Hourly customers tend to use it more, because a short job is often a test or a comparison and those want several addresses quickly.

A realistic count for two hours

Take a reconnect cycle of roughly thirty to sixty seconds, including the time for the new session to come up and for your tool to notice. If you rotated continuously and did nothing else, two hours would give you somewhere between one hundred and two hundred rotations. Nobody does that, because each rotation is dead time for the job. A more useful figure is what a working session pulls: a scraper that rotates every five minutes sees about twenty-four addresses in two hours, one that rotates every fifteen minutes sees eight, and a login session that rotates once because a page misbehaved sees two.

Will all of those be distinct? Mostly, but not always. Carriers do reuse addresses, especially on a quiet pool at a quiet hour, so a run of twenty rotations might include a repeat or two. If a specific address must not come back, check it after each rotation and rotate again. That costs a minute and happens rarely.

Sticky or rotating: pick per job

Rotating suits jobs where every request should look like a different visitor: comparing search results, sampling prices, checking that an ad serves across a metro, collecting public pages at a polite pace. Set a timer, or rotate from the script when a response changes shape, and let the carrier pool do the rest.

Sticky suits jobs where one visitor should stay one visitor: a login, a checkout, a session in an antidetect profile, a support conversation on a site that ties the session to the address. Buy the line, leave the rotation link alone, and the address stays until the carrier moves it, which for most sessions is longer than your two hours. If the session must stay on one address for a whole day, buy the day instead and rotate only when something goes wrong.

What one line is not

One hourly line is one SIM, and so at any moment it has one address. If you need ten different addresses at the same time, you need ten lines, which on 4G is $20 for two hours and gives you ten dedicated SIMs, possibly in ten cities. One line rotating fast gives you many addresses over time, not many at once. Choosing between those two shapes is the real pool-size question, and the dashboard makes both easy to buy.
