The dedicated vs shared proxy choice looks like a price question, but it is really a question about who else is using your IP address. A shared proxy puts you on an IP alongside other customers you will never meet. A dedicated proxy gives one IP to one customer, so its history is your history. This article explains what that difference does to reputation, blocks and stability, and when the cheaper shared option is perfectly reasonable.
What "shared" and "dedicated" actually mean
A proxy is an IP address that forwards your traffic. Websites see that IP instead of yours. The question is how many customers send traffic through the same address at the same time.
- Shared proxy: the provider sells the same IP to several customers. Each of them gets credentials, and all of their traffic leaves from one address.
- Dedicated proxy: the IP is assigned to a single customer for the length of the order. Nobody else's requests come from it.
Both kinds can come from datacenter, ISP or residential networks, and both can use HTTP or SOCKS5. "Dedicated" says nothing about the network type; it only describes who holds the IP. If the network type is your open question, the comparison of datacenter and static ISP proxies covers it, and the SOCKS5 vs HTTP proxy guide covers protocols.
Dedicated vs shared proxy: the reputation problem
Websites, ad platforms and marketplaces do not judge requests in isolation. They keep score on IP addresses: how many accounts have logged in from this address, how many failed logins, how many requests per minute, whether it was flagged for spam or scraping last week. That score follows the IP, not the person.
On a shared proxy you inherit the score created by every other user. If one neighbour runs an aggressive scraper, mass-registers accounts or sends spam, the IP gets rate-limited, challenged with CAPTCHAs or blocked. You did nothing wrong, but your traffic comes from the same address, so you get the same treatment.
This is the "bans from neighbours" problem, and it shows up in a few predictable ways:
- Login checks on accounts you manage. A platform sees one IP touching many unrelated accounts, some of them yours and some belonging to strangers, and asks for extra verification.
- CAPTCHAs on ordinary browsing. The IP has been used heavily by someone else, so every page load becomes a challenge.
- Silent rate limits. Requests start returning errors or empty results because the address already used up its allowance for the hour.
- Blocklists. Some services subscribe to lists of abused IPs. Once a shared IP lands on one, it can stay there long after the abuser has left.
With a dedicated proxy, the reputation still matters, but you control it. If the IP gets challenged, it is because of how you used it, and you can change your behaviour. That predictability is the main reason teams that run accounts or long sessions pay more for one-user IPs.
A dedicated IP is not a shield. It does not prevent bans, and it will not save an account that breaks a platform's rules. Follow each platform's terms; a clean IP only removes one source of trouble you cannot see.
Side-by-side comparison
| Shared proxy | Dedicated proxy | |
|---|---|---|
| Who uses the IP | Several customers at once | One customer |
| IP reputation | Shaped by everyone on it | Shaped by your own use |
| Bandwidth | Split between users | Not split with other customers |
| Account logins | Risky: one IP touches many strangers' accounts | One IP, your accounts only |
| Troubleshooting | Hard to tell whose traffic caused a block | Cause is in your own logs |
| Price per IP | Lower | Higher |
| Good fit | Light, anonymous browsing, low-stakes tests | Account management, ads, long sessions, allowlisting |
Speed and stability
Reputation is the big difference, but capacity matters too. On a shared IP, your requests compete with other users' requests for the same connection and the same per-IP limits on the target site. When a neighbour starts a heavy job, your response times can jump without warning.
A dedicated IP removes that competition from other customers. You still share the provider's network, as every proxy does, but nobody else consumes the allowance that a website grants to that address. For workflows that compare results over time, such as rank tracking or price monitoring, consistent behaviour is often worth more than raw speed.
When a shared proxy is fine
Shared proxies are not useless. They make sense when:
- You only need to view public pages from another country once in a while.
- Nothing is logged in, so there is no account to put at risk.
- A blocked request costs you nothing but a retry.
- You are testing whether a proxy-based approach works at all before buying.
If any of those describe your work, the lower price is a fair trade. The moment you log into accounts, run ads, allowlist an IP on a partner's system or depend on the same address for weeks, the trade turns against you.
When you need a dedicated proxy
Choose a dedicated proxy when the IP's history affects the outcome:
- You manage accounts. Social media, seller centres on marketplaces like Shopee or Lazada, and ad accounts all watch where logins come from.
- You need a stable identity. Long sessions, logins that should not trigger fresh verification, or tools that pin one account to one IP.
- Someone allowlists your IP. An API, a payment gateway or a client's firewall that accepts traffic only from known addresses needs an IP nobody else uses. See static IP allowlisting for that pattern.
- You need clean measurements. Ad verification and geo testing give misleading results if the IP is already flagged.
How Cloudj proxies fit
Cloudj sells dedicated proxies only, no shared pool. Each dedicated IPv4 proxy is a static IPv4 address registered to an ISP, not a datacenter range, assigned to one customer and described as fast and stable. In the United States and Vietnam there is also a static residential option: an IP from a home-broadband ISP that stays the same and looks like a regular user. See the US proxy page and the Vietnam proxy page for those two markets.
Proxies are available in Vietnam, the United States, Japan, South Korea, Singapore, Hong Kong and the United Kingdom, and the console shows what is in stock. You order 1 to 1,000 IPs on a 1, 3, 6 or 12 month term, pay from your account balance and get host, port, username and password within a few minutes. Authentication is username and password by default, or an IP whitelist of up to 20 addresses.
The main argument against Cloudj here is cost and scale: if your job needs thousands of different IPs per hour, a set of static dedicated IPs is the wrong tool. The static vs rotating proxy article explains that case. For the full picture of dedicated proxies, read the dedicated proxy guide.
FAQ
Is a dedicated proxy the same as a private proxy?
Usually, yes. Providers use "private" and "dedicated" for the same idea: one IP, one customer. Check the product description, because some "private" offers share an IP among a small group.
Can a dedicated proxy still be blocked?
Yes. A dedicated IP can be challenged or blocked because of how it is used, or because some sites are strict with the network range it belongs to. The difference is that the cause is under your control.
Does a dedicated IP have a clean history?
Previously used addresses can carry old reputation from before they were assigned to you. If an IP behaves badly from the first request, test it on the sites you care about early in the order.
How many dedicated proxies do I need?
A common starting point is one IP per account or per identity you need to keep separate. The how many proxies do I need guide walks through the maths.
Choosing your next step
If you log into accounts, run ads or rely on an allowlisted IP, start with a dedicated proxy and keep one IP per identity. You can check live prices on the pricing page and order dedicated IPs in the Cloudj console, where the stock per country is shown before you pay.
