Choosing the right network begins with the basics covered in the buyer’s guide to proxy services, namely how providers source and route IPs. This page explains the four network families (Datacenter, ISP, Residential, Mobile), how they behave in practice, and how to decide which one fits a job.
What a “proxy network type” means
A proxy network type classifies proxies by where the IPs come from and how traffic is routed through the provider’s gateway. The four families are Datacenter, ISP, Residential, and Mobile.
The network type is separate from protocol (HTTP or SOCKS), authentication, or rotation settings. Think of it as the IP supply chain behind your gateway and session options.
Datacenter proxies
Datacenter proxies use IPs owned by hosting companies and cloud providers rather than access ISPs. They are fast, predictable, and the most cost efficient at scale, but are also the most likely to be flagged by platforms that distrust hosting ASN ranges.
They shine on tolerant targets, internal tooling, and bulk jobs where price per IP matters. Expect clear concurrency limits, stable endpoints, and straightforward allowlisting or Username/Password auth. If your workload hits stricter sites, stickiness and lower request rates help, but reputation ceilings remain because the ASN reveals a hosting origin. For configuration details and deeper tradeoffs, see the datacenter proxies guide.
ISP proxies
ISP proxies use IPs registered to access providers yet hosted in data centers or provider infrastructure, giving you static residential-looking IPs with datacenter uptime. They carry higher trust than pure DC on many sites because the ranges belong to consumer ISPs.
Use them when you need long-lived sessions, consistent fingerprints, and fewer blocks than DC can deliver, but you still want stable endpoints and simpler billing. Costs are higher than DC and capacity is smaller, so plan usage by accounts or flows that benefit from persistent identity. For pros, cons, and setup patterns, see guide to ISP proxies.
Residential proxies
Residential proxies route through real consumer connections, often via peer-to-peer SDK supply. You get broad city-level coverage and large IP pools that rotate on demand or by time, which helps distribute requests and avoid rate-based throttles.
They are ideal when targets filter hosting and many ISP subnets, or when you need diverse geos and ASNs quickly. Tradeoffs include variable speeds, changing IP quality due to rotating supply, and pricing that is commonly per GB. Treat sessions as ephemeral unless you explicitly request sticky windows with a gateway param. For a full breakdown and control tips, see residential proxy guide.
Mobile proxies
Mobile proxies route through carrier networks behind CGNAT, so a single public IP may represent many real devices. Some platforms assign higher tolerance to carrier ASNs because mobile traffic is noisy by design.
Choose mobile when targets are very strict toward datacenter and Res or when a mobile ASN specifically improves deliverability. Expect the highest prices, limited exact geo down to city for some carriers, and frequent rotation that you control via request or timer. Bandwidth is often metered and concurrency limits can be tighter. For methods to hold sessions and plan costs, see mobile proxies guide.
Quick comparison
| Attribute | Datacenter | ISP | Residential | Mobile |
| IP source | Hosting providers | Access ISPs (static) | Consumer connections (P2P) | Cellular carriers (CGNAT) |
| Trust on strict sites | Lowest | Medium-high | High | Highest in many cases |
| Rotation behavior | Optional, usually static | Static by default | Rotating by request or time | Rotating by request or time |
| Sticky sessions | Easy and long | Easy and long | Available with time windows | Available with time windows |
| Pool breadth | Large but hosting ASNs | Smaller than DC | Very large and diverse | Smallest, tied to carriers |
| Pricing model | Per IP most common | Per IP higher than DC | Per GB common | Per GB highest |
| Typical latency | Low and stable | Low and stable | Variable | Variable |
| Best for | Cost-scale tasks, tolerant targets | Long-lived accounts, tougher targets | Geo diversity, anti-hosting filters | The strictest targets, mobile-ASN needs |
Choosing the right network for the job
Pick DC when price per identity is the top constraint and the target does not hard-block hosting ranges. Move to ISP when you need static, more trusted IPs for long-lived sessions. Use Residential for geo breadth and rotating pools. Use Mobile when only carrier ASNs consistently work.
A practical way to decide is to map the target’s tolerance and your budget. If DC fails due to ASN filtering or fast blocks, step up to ISP. If ISP still struggles or you need constant IP churn across many geos, switch to Residential with rotation. If the target reacts best to carrier ASNs, plan a smaller, focused Mobile allocation.
Rotation, stickiness, and sessions
Rotation changes the exit IP per request or at a time interval while a sticky session holds one IP for a defined TTL. The gateway usually exposes both, allowing you to trade freshness for continuity.
Use rotation for bursty scraping and distribution across large pools. Use stickiness for logins, carts, or flows that break on IP change. Common controls include session=<id> on the username, ?session=, request-count rotation, or time-based windows like 5, 10, or 30 minutes.
Geo and ASN targeting realities
City and ASN targeting are strongest on Residential and Mobile because supply is tied to end-user lines and carriers. DC and ISP offer many countries and cities but remain in hosting or limited ISP ranges that some sites classify differently.
If your KPI depends on local inventory, language, or regional rules, verify that the provider’s city granularity matches your plan and that the ASN family aligns with the platform’s expectations. Always sample test routes before committing budgets.
Auth, gateways, and concurrency
Most networks support Username/Password and IP allowlisting. Gateways present a single hostname with ports for HTTP and SOCKS, plus optional sticky and rotate ports.
Concurrency limits cap active connections per plan. Plan headroom above your peak threads to avoid throttling. If your tool opens many short-lived sessions, prefer providers that state hard limits clearly and expose 429 or similar signals rather than silently dropping connections.
Bandwidth, billing, and limits
Datacenter and ISP commonly price per IP or package size, sometimes with unlimited traffic and an explicit thread cap. Residential and Mobile often price per GB with concurrency caps and fair use rules.
Audit the fine print for rotation TTLs, traffic measurement points, allowed targets, and refund terms. If you buy per GB, measure your tool’s real bandwidth footprint on a small trial because retries, images, or JavaScript can multiply usage.
Stability and troubleshooting
Expect the most stable endpoints from DC and ISP since IPs are static and under provider control. Residential and Mobile quality varies as supply changes. Keep your client tolerant of occasional timeouts by adding retries with backoff and smart pacing.
If results degrade, capture the failing endpoint’s ASN and error patterns. Switching to a different ASN family often resolves blocks faster than retrying the same range.
