Dedicated vs shared proxies: what sharing an IP costs you, and when it is fine

Dedicated vs shared proxies is a question of who else uses your IP address. A dedicated proxy (also sold as a private proxy) is an address assigned to you alone for the term you rent it. A shared proxy is an address several customers use at the same time. Shared costs less per IP; dedicated gives you the address's whole reputation and its whole rate-limit budget. Choose shared for low-stakes reading of public pages, and dedicated for anything tied to your identity: logins, allowlists, and targets that remember an address.

The rest of this guide is about what "shared" means once you are using it, because the price difference is easy to see and the costs are not.

#Dedicated vs shared proxies: the definitions

The names are marketing, not standards. "Private", "dedicated", "semi-dedicated" and "shared" mean what a vendor's plan page says they mean, so always read the number of users per IP rather than the label.

#What "shared" means in practice

#How many users per IP

The number matters more than the word. An IP split between 3 customers behaves differently from one split between 30. Some vendors publish the figure; some say "shared" and leave it there. If a plan does not state how many customers use each address, assume it is more than you would like, and ask.

A related model is the shared pool: every customer draws exits from one large set of addresses, usually billed per GB. Residential proxies work this way by nature, and so do rotating datacenter products. Nobody holds a pool IP, so the dedicated vs shared question is replaced by a rotating vs static one; rotating vs static proxies covers that trade-off.

#Whose traffic taints the address

Targets see an IP, not a customer. Every request through a shared address adds to one history:

• If another customer hammers a site, the address gets rate-limited or blocked there, including for you.
• If another customer's traffic trips a bot-protection score, your requests start meeting CAPTCHAs on that site.
• If the address lands on a reputation list, it lands there for everyone on it.

You will usually not know why. You see a block that your own traffic does not explain, with no way to see the traffic that caused it. That, more than the price, is the cost of sharing.

#Rate limits are split

Many sites allow a certain number of requests per IP per minute. On a dedicated IP the whole allowance is yours. On a shared one it is split with whoever else is sending to the same site at the same time, and you do not know how many that is. A job that fits comfortably on one dedicated IP can hit 429 Too Many Requests on a shared one for no reason visible to you.

#Accounts on one address look related

Platforms link accounts that log in from the same address. On a shared IP, your account shares an address with strangers' accounts. At best that is noise; at worst a platform treats them as one operator and acts on all of them. This is why every guide to account work, ours included, says dedicated. The account management use case explains the setup.

#Traffic allowances

Shared plans often come with a traffic cap or a small included allowance per IP, because the vendor is dividing one address's bandwidth between several customers. Check what happens past the allowance: a per-GB charge, a slowdown, or a hard stop.

#The price trade-off

A shared IP is cheaper per address, and that is the whole case for it. Whether it is cheaper per useful request is a different question.

Take an illustrative case: a shared IP priced at two thirds of a dedicated one, split between three customers who all send to the same site. You pay two thirds of the price for, at worst, one third of the per-IP rate allowance on that site. If you run into the limit, you need more shared IPs to do what one dedicated IP would, and the saving disappears. If nobody else sends to your target, you get the full allowance at the lower price, and shared is the better deal.

Sharing sometimes comes with volume too. Oxylabs' smallest ISP plan is 10 IPs at $1.60/IP, shared with up to 3 users, as listed on their pricing page on 2026-09-29. If sharing suits your job and you need ten or more addresses, that is a good price, and it is fair to say so.

A quick way to decide:

1. Estimate the requests per IP your job needs on its busiest target.
2. Assume the other users on a shared IP send about as much as you do. If your job still fits inside the target's per-IP limit, shared can work.
3. Price the failure. If a blocked address means a lost account or a broken allowlist, the saving on shared is not worth it. If it means one retry on another address, it may be.

#When shared proxies are fine

• Reading public pages on lenient targets. Prices, listings, documentation and open data where nobody is logged in and the site does not block aggressively.
• Occasional checks. A handful of requests a day to see what a page shows from a given location.
• Testing before you commit. A cheap way to see whether a location or network type works for your target at all.
• Many small addresses, low volume each. Wide, light work where no single IP carries much.

#When you need a dedicated proxy

• Logins and accounts you own. One address per account, carrying nobody else's history.
• IP allowlists. A partner firewall or API that accepts your address should see only your traffic from it. Allowlisting an IP that strangers also use lets them in too.
• Protected targets. Where one bad actor on the address gets it blocked, you want to be the only actor.
• Steady, heavy traffic. Dedicated IPs are usually unmetered, so volume does not raise the bill.
• When you need to explain a block. On a dedicated IP, every block is something your own traffic did, which means you can fix it.

#Dedicated and shared proxies at ProxyHive

ProxyHive ISP proxies and datacenter proxies are both sold per IP from a single address, and both come on three plans:

Dedicated starts at $3.20/IP a month for one IP and is listed first, because most static-IP work needs it. The shared and premium prices, and the per-GB rate for extra shared traffic, are on the ISP pricing page, at the price checkout charges. ISP is ordered by country, region, city and carrier; datacenter by country, region and city.

If you need just one or a few addresses, buying a single static IP walks through the order, and what is an ISP proxy explains why a consumer carrier's address is worth keeping to yourself. Every use has to fit the allowed-use policy, published before you buy.
