Static vs rotating proxies comes down to one question: how long an IP stays yours. With a static proxy, the same IP address stays assigned for as long as you hold it, often for months. With a rotating proxy, the IP changes per request or on a timer, drawn from a pool. Pick static for anything that needs one stable identity or a fixed address on an allowlist, and rotating for high-volume work where each request should look like a different visitor. The IP type underneath (datacenter, ISP, residential or mobile) decides how much trust either mode starts with.
Key takeaways
- A static proxy keeps one IP for as long as you hold it; a rotating proxy changes the IP per request or on a timer, drawn from a pool.
- How long you keep an IP (static vs rotating) and who else uses it (dedicated vs shared) are separate choices.
- Most products sold as static residential are ISP proxies: IPs registered to consumer providers but hosted in data centers.
- Outside mobile, most static IPs are server-hosted: datacenter, or ISP sold as static residential. A held mobile IP is still a carrier address shared with real subscribers, which sites are reluctant to block.
- Static ISP still wins two jobs: an address that must stay fixed for months or sit on an allowlist, and checkouts decided in milliseconds.
What Is the Difference Between Static and Rotating Proxies?
Static proxies assign you one IP address and keep it. Every request leaves from that address until you release it, so the target sees one consistent visitor. Rotating proxies connect you to a gateway backed by a pool of addresses, and the gateway swaps the exit IP per request or on a set interval, so the target sees many unrelated visitors.
Between the two sits a third mode. Sticky sessions hold one IP from a rotating pool for a set window, then let it go: a rotating product that behaves like a static one for the length of a task.
Keep one distinction separate from all of this. How long you keep an IP is one question, and whether anyone else uses it at the same time is another: the dedicated vs shared proxies choice. Dedicated IPs can rotate on demand, and static IPs can be shared between several customers.
Static vs Rotating Proxies: Key Differences
Put a static vs rotating proxy side by side and the trade-offs line up like this:
| Feature | Static proxies | Rotating proxies |
|---|---|---|
| IP persistence | One IP for as long as you hold it | New IP per request or on a timer |
| How the IP is assigned | Allocated to your account | Drawn from a pool through a gateway |
| Session continuity | Full: logins and carts survive | None, unless you use a sticky session |
| What the target sees | One consistent visitor | Many unrelated visitors |
| When an IP gets flagged | It stays flagged until replaced | The next request leaves from a fresh IP |
| Allowlisting | Easy: one address to approve | Impractical: the address keeps changing |
| Typical billing | Per IP, monthly | Per GB of traffic |
| Best for | Accounts, logins, allowlisted access | Scraping, monitoring, data collection at volume |
The flagged-IP row deserves a second look. On a dedicated static IP, reputation comes from your traffic alone, which is an asset while it stays clean and a liability once a target marks it. Fraud-scoring services rate each address, and a flagged static IP carries that score into every session until it is replaced; our guide to reading IPQualityScore fraud scores shows what those numbers mean. Rotation spreads requests across many addresses, so one bad response does not follow the next request, but no single address ever builds a history with the target either.
Static and Rotating Across IP Types
Static and rotating are modes, not IP types, which is why rotating vs static proxies is only half the decision. Each of the four IP types is sold in one or both modes, and the type sets how a scored site reads the address before a single request is judged.
| IP type | Where the IP comes from | Static form | Rotating form | How scored sites read it |
|---|---|---|---|---|
| Datacenter | Hosting provider server ranges | Common: dedicated or shared static IPs | Pools of server IPs | Labeled as hosting, filtered first |
| ISP | Consumer ISP ranges hosted on servers | The main form, often sold as static residential | Less common | Reads as broadband; leased ranges can cluster |
| Residential | Home broadband connections | Limited: home IPs are often reassigned | The main form: large rotating pools | Consumer traffic; pool quality varies |
| Mobile | Carrier networks behind CGNAT | Dedicated mobile device: held, not fixed for months | Per-request or sticky on carrier IPs | Shared with real subscribers, costly to block |
Datacenter proxies come in both modes and cost the least per IP, which suits unprotected targets and testing. Hosting ranges are labeled as such in commercial IP databases, so neither mode helps much against a site that filters by IP type. ISP proxies sit at the other end: static by design, fast, and usually exclusive to one customer for as long as they rent the address.
Rotating vs Static Residential Proxies
Rotating residential proxies are pools of IPs from real home broadband connections. Requests exit through those connections, and the provider rotates the exit per request or holds it for a sticky window. Pool quality depends on how the provider sources those devices, and sourcing varies widely across the market, as our look at where budget residential IPs come from shows.
The static residential label is a different story. Most offers under that name are ISP proxies: the address is registered to a consumer provider, so a basic lookup reads it as broadband, but it runs on server hardware in a data center. That explains the contradiction buyers notice, a "residential" IP with data center speed and uptime. Home lines rarely keep one public IP long enough to sell as static, because many consumer connections receive dynamic addresses.
So choosing between rotating and static residential is really choosing between rotating residential and ISP: home-sourced variety against one fixed, fast, server-hosted address.
Mobile Proxies: Sticky or Per-Request on Carrier IPs
Mobile changes the trade-off. Carriers place large numbers of subscribers behind shared public addresses using carrier-grade NAT, and Cloudflare's research on CGNAT notes that a single IPv4 address may represent hundreds or even thousands of users, so IP-based blocking against one can hit large groups of legitimate visitors. Banning a carrier IP risks cutting off a site's own customers. Of the four types, mobile is the one sites are least willing to block.
That trust carries into both modes. On a rotating mobile pool, each request can get a new carrier IP for scraping and monitoring, or one IP can be held for a sticky window when a flow needs continuity. Residential pools offer the same two modes, but their static form is usually an ISP address in a data center. On mobile, even a held IP stays a carrier address behind CGNAT. How long to hold a sticky session and when to rotate is a topic of its own, and our explainer on sticky sessions for mobile proxies covers the basics.
Timed rotation sits between per-request and sticky: the gateway holds each IP for a set interval, then swaps it, which suits a crawl that needs a few minutes of continuity per batch without managing session IDs. On VoidMob's rotating pool, each proxy list carries its own setting: per-request, sticky (the same device for as long as it stays online), or a timer with presets from 30 seconds to 1 hour and a custom interval up to 24 hours.
Dedicated mobile proxies are the closest mobile gets to static. On VoidMob, each dedicated proxy is one real 4G/5G device that carries only your traffic and holds its carrier IP until you rotate it, from the dashboard or a private rotation link, at most once a minute. You get clean IP history, a 95%+ trust score and a high-speed connection. What no provider can sell is months of the same address: carriers can reassign a mobile IP on their own, so anything sold as a "static mobile proxy" is a held IP, not a permanent one.
When a static ISP proxy is the right call
Some jobs need one address that never changes. Corporate tools and B2B APIs often grant access by IP allowlist, the way GitHub's IP allow list does for organizations, and a rule written for one address breaks the day that address changes. Timed checkouts decided in milliseconds also favor server-hosted ISP IPs. For both jobs static ISP is the honest pick, as our ISP vs mobile comparison explains in detail.
Rotating or held, on real carrier IPs
A shared 4G/5G pool that rotates per request or holds a sticky session, and dedicated devices that hold one carrier IP and rotate on your schedule.
FAQ
What are the two types of proxies?
In networking, the two types are forward proxies, which act for the client, and reverse proxies, which sit in front of a server. When you buy proxies, the split that matters most is static vs rotating: a static proxy keeps one IP address for as long as you hold it, and a rotating proxy changes the IP per request or on a timer from a pool. By IP source, proxies are datacenter, ISP, residential or mobile, and each can be sold in one or both modes.
What are all the types of proxies?
Proxies are usually grouped four ways: by IP source (datacenter, ISP, residential, mobile), by persistence (static or rotating, with sticky sessions in between), by exclusivity (dedicated or shared) and by protocol (HTTP, HTTPS or SOCKS5). Any single proxy connection combines one option from each, such as a rotating mobile proxy over SOCKS5 or a dedicated static ISP proxy over HTTP.
Which proxy type is best?
No single type is best for every job. Mobile proxies carry the most trust on sites that score traffic and suit scraping protected targets and multi-account work. Residential pools cover broad, lightly protected scraping at a lower cost per GB. ISP proxies win when an address must stay fixed or sit on an allowlist, and datacenter proxies suit unprotected targets and testing.
Are static residential proxies the same as ISP proxies?
In most cases, yes. Products sold as static residential are usually ISP proxies: IP addresses registered to a consumer internet provider but hosted on servers in a data center. That is why they combine a broadband label with data center speed and uptime. Truly home-hosted static IPs are rare, because many home connections receive dynamic addresses.
Can a mobile proxy have a static IP?
Not in the strict sense. A dedicated mobile proxy holds its carrier IP for long sessions and changes it only when you rotate, but carriers can reassign mobile addresses on their own, so it cannot guarantee the same IP for months. For an address that must stay fixed or sit on an allowlist, a static ISP proxy is the right tool.
Is a static or rotating proxy better for web scraping and data mining?
Rotating, in most cases. Scraping and data mining send many independent requests, and proxy rotation spreads them across many IPs so rate limits and blocks do not stack on one address. Use a sticky session when a scrape needs several steps from the same IP, such as search, results and detail pages. On protected targets, rotating mobile IPs hold up better than datacenter or residential pools.
Are proxy services legal?
Using a proxy is legal in most countries. Proxies are a standard networking tool that businesses use for testing, security and data collection. What can break a law or a contract is the activity routed through the proxy, such as fraud or ignoring a site's terms, and the same rules apply with or without one.
Static or Rotating: Which Should You Choose?
Match the mode to the job first, then pick the IP type:
- Scraping, price and SERP monitoring, ad checks, data mining. Rotating, per request. VoidMob's rotating mobile proxy pool gives each request a fresh carrier IP and bills per GB, with sticky sessions on the same pool for multi-step flows.
- Multi-account work, logged-in sessions, social media. One held IP per account. On a dedicated mobile device, each account keeps its own carrier IP, rotated on your schedule rather than per request.
- Allowlisted access, an IP fixed for months, millisecond checkouts. Static ISP. Mobile is the wrong tool for an address that can never change.
- Unprotected targets and internal testing. Datacenter, static or rotating, whichever is simpler to run.
Many setups run two of these side by side: a rotating pool for collection and dedicated devices for accounts, with a static ISP address only where a system demands one. Current VoidMob prices for the rotating pool and dedicated devices:
