A dedicated IP is a proxy IP address assigned to you alone — no one else routes traffic through it, so its reputation is entirely in your hands. A shared IP is used by multiple customers at once, which makes it cheaper but means a stranger's behavior can affect how sites treat that address. The right choice depends on the job: dedicated IPs win when you need a stable, trusted identity (account management, anything tied to one login); shared IPs are fine — and economical — when you want volume and IP diversity, like rotating through a large pool to scrape.
This guide compares the two across the factors that matter, maps each to real use cases, and shows where they sit in a proxy provider's lineup. If you are choosing a provider overall, start with how to choose a proxy provider.
A dedicated (or private) IP is exclusively yours for the duration of your plan. Because no one else touches it, you control its entire history: if the IP has a clean reputation, that is your doing, and nothing a stranger does can taint it. This is the model behind static residential (ISP) proxies and dedicated datacenter proxies. It is closely related to a private proxy — the terms are often used interchangeably.
A shared IP is used by several customers simultaneously. Providers offer it because spreading the cost of an IP across users makes it far cheaper. The trade-off is reputation: you inherit whatever the other users do on that address. On a quality network this is well managed, but a shared IP can occasionally arrive already rate-limited or flagged by a target site because of someone else's activity. Large rotating residential pools are shared by nature — you are constantly drawing fresh IPs from a pool many customers use.
| Factor | Dedicated IP | Shared IP |
|---|---|---|
| Who uses it | You alone | Multiple customers |
| Cost | Higher (priced per IP) | Lower (cost spread) |
| Reputation control | Full — only your activity | Partial — inherited from others |
| Consistency | Stable, predictable identity | Varies; often rotating |
| Best for | Account management, one-login tasks | High-volume scraping, IP diversity |
| Ban blast radius | Only affects you | Can pre-exist from others |
The dedicated-vs-shared question often maps onto static vs rotating proxies: static IPs tend to be dedicated, rotating pools tend to be shared.
A dedicated IP is used by one customer only, so that customer fully controls its reputation. A shared IP is used by several customers at once, which makes it cheaper but means each user inherits the others' activity on that address. Dedicated favors stability and control; shared favors cost and IP diversity.
Not universally — it depends on the job. A dedicated IP is better for account management and reputation-sensitive work because it is stable and only your activity affects it. A shared (rotating) IP is better for high-volume scraping where diversity across many addresses is the goal and cost matters.
Because the cost of the IP is spread across multiple customers using it at the same time. The trade-off is that you do not control its reputation alone — another user's behavior on the same address can affect how target sites treat it.
It does not guarantee against bans, but it removes one risk: because only you use the address, it will not arrive pre-flagged by someone else, and any reputation it has is the result of your own behavior. That control is the main reason to choose dedicated for account work.
They overlap but are not identical. Dedicated means used by you alone; static means it does not change over time. In practice dedicated proxy IPs (like static residential or dedicated datacenter) are usually static, which is why account-management tasks rely on them.
Usually shared, rotating IPs from a large pool, because scraping benefits from spreading requests across many addresses. Use dedicated IPs for scraping only when a task requires a consistent identity, such as a logged-in session you must keep stable.
Dedicated and shared IPs are not better or worse in the abstract — they answer different needs. Choose a dedicated IP when you need a stable, trusted, reputation-controlled identity for account management and one-login tasks. Choose shared, rotating IPs when you want volume, diversity, and lower cost for scraping. Many operations use both: dedicated for the accounts, shared for the data collection.
SpyderProxy offers both — dedicated static residential from $3.90/day and a shared rotating residential pool from $1.75/GB across 195+ countries with city-level targeting.
