Residential proxies, in plain terms, are the addresses of ordinary home users: IPs that an internet provider has assigned to real apartments and offices. Mobile proxies are addresses of cellular carriers, the ones smartphones use. Datacenter proxies are addresses rented from a hosting company. All three pass your traffic through themselves, but websites see them differently and trust them differently.
This article is for anyone choosing a proxy type for a specific task who does not want to overpay for residential traffic (from 290 ₽ ≈ $3 per GB) where a datacenter IPv4 from 79 ₽ (≈ $0.85) would do, or lose accounts on datacenter addresses where mobile ones are needed.
Residential proxies in plain English: where the IPs come from
When you sign up for home internet with Rostelecom or Deutsche Telekom, the provider assigns your router an IP from its own range. That range is registered to the provider as an ISP, not as hosting, and GeoIP databases flag it as “residential”. Websites see such an address and assume there is an ordinary person at home behind it.
A residential proxy service builds a pool of such addresses. The sources vary: SDKs in apps where users agree to share their connection in exchange for free features, partnership programmes with ISPs, the provider's own device networks. The customer connects to a single gateway, and the gateway sends each request out through a random home IP in the required country or city.
Hence the characteristics: the pool is huge (at ProxyFarm, 48 countries with city-level targeting), you can get an address almost anywhere in the world, but the IP is not yours and not permanent. You pay per gigabyte because the provider pays for the bandwidth of real people.
How mobile proxies differ from datacenter proxies
A mobile proxy is a physical 4G/LTE modem with an MTS, Beeline, MegaFon or Tele2 SIM card sitting in the provider's farm. Traffic goes over the cellular network, and the website sees the carrier's IP. The key feature is NAT: thousands of subscribers share one external carrier IP at the same time. Banning it would hurt the platform's own users, so mobile addresses get the highest level of trust.
A datacenter proxy is a virtual machine or dedicated server in a datacenter with its own IPv4 or IPv6. The range is registered to a hosting company, and any platform can tell from the ASN in a millisecond that this is not a person. In return it is the fastest and cheapest option: 100 Mbit/s and up, 5–20 ms latency, and a dedicated IPv4 costs from 79 ₽ per month.
The core difference is who owns the address and how often it changes. A datacenter IP has one owner and a fixed address; a mobile proxy has one modem, but the address rotates through the carrier's pool by link or by timer.
Datacenter vs residential vs mobile proxies: comparison table
The table below collects the parameters people usually choose by. Prices are ProxyFarm's at the time of publication; other providers are in the same ballpark.
| Parameter | Datacenter (IPv4/IPv6) | Residential | Mobile |
|---|---|---|---|
| IP source | Datacenter, hosting provider | Home ISPs, real apartments and offices | Cellular carriers, 4G/LTE modems in a farm |
| How platforms see it | Hosting / Datacenter: low trust | ISP / Residential: high trust | Mobile / Cellular: maximum trust thanks to NAT |
| Pricing model | Per IP per month: IPv4 from 79 ₽, IPv6 from 12 ₽, shared from 35 ₽ | Per traffic: from 290 ₽/GB | Per channel per month: from 490 ₽ shared, 2 500 ₽ dedicated device, unlimited traffic |
| Speed | 100+ Mbit/s, 5–20 ms latency | 5–30 Mbit/s, depends on the end user's home connection | Up to 40 Mbit/s on a dedicated device, 40–100 ms latency |
| IP stability | Static, yours for the whole rental period | Rotation on every request or a sticky session up to 30 minutes | Rotation by link or by timer, address from the carrier's pool |
| Geography | 17 countries, choice of datacenter country and city | 48 countries, city-level targeting | Russia: Moscow, Saint Petersburg, Kazan; region set by the SIM |
| Who else uses the IP | Only you (dedicated) or a few customers (shared) | The real home user plus other customers of the service at different times | Thousands of carrier subscribers behind the same NAT, which is exactly what protects you |
| Best scenarios | High-frequency scraping, price monitoring, SERP tracking, QA, anywhere speed matters more than trust | Geo-ad verification, sites with strict anti-fraud, foreign platforms, e-commerce in different countries | Multi-accounting on social networks, Avito, Telegram, WhatsApp, advertising, account warm-up |
| Weak points | Captchas and checks on social networks and marketplaces, suspicion at registration | Expensive at high traffic volumes, unpredictable speed | Higher latency, limited geography, pricier per unit for small tasks |
How to choose a type for your task: four questions
Instead of memorising the table, ask yourself four questions. The answers will point to a type unambiguously.
- Does the platform check the IP type? Social networks, Avito (Russia's largest classifieds site), marketplaces, banking and payment services: yes. Open websites, catalogues, search engine results, APIs without authentication: no. If no, take datacenter proxies and stop overpaying.
- How much traffic? Scraping a 500 000-page catalogue eats 50–100 GB. On residential proxies that is tens of thousands of rubles a month; on datacenter or mobile it is a flat fee. Above 20–30 GB a month, residential proxies are rarely justified.
- Do you need a specific country outside Russia? Datacenter proxies cover 17 countries, residential 48 with city-level precision. ProxyFarm's mobile proxies are Russian carriers only. For testing geo-targeted ads in Brazil the choice is obvious.
- Are you working with accounts or with data? Accounts live longer on mobile and residential addresses. Data is collected faster on datacenter ones. If you need both, split them: accounts on mobile, scraping on IPv4.
Typical mistakes when choosing
Mistakes come in two flavours: saving money where you must not and overpaying where you need not.
- Datacenter IPv4 for registering Instagram or Telegram accounts. Cheap, but the accounts hit verification within hours. The 400 ₽ saved does not pay for the lost profiles.
- Residential proxies for scraping Yandex or Wildberries. Traffic burns through gigabytes, the bill grows, and there is almost no gain in success rate: these platforms react to request frequency, not IP type. Datacenter rotating proxies at 1 490 ₽ a month do the job for less.
- Mobile proxies for downloading large files or video. Latency and the channel cap will make the work slow. This is a job for IPv4.
- Shared IPv4 for anything other than tests. Bulk addresses are shared between several buyers, and you do not know the IP's history. For anything serious, dedicated only.
- Buying without checking. Run any IP type through a spam-database and geo check before work. ProxyFarm checks every address before delivery and replaces it free of charge within the first 24 hours if it does not suit the platform.
What next: how to test before buying
The sensible order is to start free and short. A ProxyFarm mobile channel is available for 1 hour with no card required: enough to log into the target platform and see how it reacts. Datacenter IPv4 and residential proxies can be rented for 1 day: for 79 ₽ or a single gigabyte of traffic you will see the real speed and success rate.
If within 24 hours it becomes clear that you picked the wrong type, you get your money back. After that it makes sense to take 30 or 90 days: a quarter comes with a 15 % discount.
Related questions
Are residential proxies legal?
Yes, provided the owners of the home IPs have consented to join the network and you use the proxies for legitimate tasks: scraping public data, ad verification, geo testing. The user is responsible for the content of the traffic; the provider is responsible for the legitimacy of the address sources.
How do residential proxies differ from mobile ones if both are “real”?
By source and pricing model. Residential proxies are home addresses in 48 countries; you pay per gigabyte, and the IP changes on every request or holds for up to 30 minutes. Mobile proxies are addresses of Russian carriers; you pay per channel per month with unlimited traffic, and the IP changes on your command. Mobile wins on platform trust, residential on geography.
Can rotating datacenter proxies replace residential ones?
For scraping and monitoring, often yes: rotating IPv4 on every request gets around rate limits more cheaply. For platforms that check the address type by ASN and ban datacenters, no: rotation does not change the fact that every address belongs to a hosting company.
Which is fastest: datacenter, residential or mobile proxies?
Datacenter: 100 Mbit/s and up at 5–20 ms latency. Mobile delivers up to 40 Mbit/s on a dedicated device at 40–100 ms. Residential is the least predictable: speed is capped by the end user's home connection, usually 5–30 Mbit/s.
