Question 1

What is the difference between shared and private proxies?

Accepted Answer

Shared proxies route traffic from 5-100+ users through the same IP address simultaneously. Private (dedicated) proxies assign an exclusive IP to a single user. The core difference is control: with shared proxies, other users' behavior directly affects your IP reputation, speed, and ban risk. With dedicated proxies, you control 100% of the traffic history on your IP.

Question 2

Are shared proxies safe to use?

Accepted Answer

Shared proxies carry inherent risk because you have no control over what other users do with the same IP. If another user sends spam, scrapes aggressively, or violates platform terms, the IP gets flagged — and you inherit that negative reputation. For low-stakes browsing or testing, shared proxies are acceptable. For account management, e-commerce, or anything where bans have financial consequences, shared proxies are a liability.

Question 3

Why are shared datacenter proxies so cheap?

Accepted Answer

Datacenter IPs cost providers roughly $0.50-2.00 per IP per month in bulk. When one IP is sold to 10-50 users simultaneously, the per-user cost drops to $0.05-0.20 per IP. Providers can offer subscriptions at $1-5/month and still profit because the infrastructure cost is divided across many customers. The tradeoff is that you share both the bandwidth and the IP reputation with every other user.

Question 4

What is a semi-dedicated proxy?

Accepted Answer

A semi-dedicated proxy is shared with a limited number of users — typically 2 to 5. This is a middle ground between shared (5-100+ users) and fully dedicated (1 user). Semi-dedicated proxies cost $3-10/month and offer better performance and lower ban risk than fully shared options. However, you still have no control over the other 1-4 users' behavior, so IP contamination remains possible.

Question 5

How do rotating proxies compare to dedicated proxies?

Accepted Answer

Rotating proxies cycle through a pool of IPs — changing the IP per request, per session, or on a schedule. They are priced by bandwidth ($3-15/GB for residential) rather than per-IP. Rotating proxies excel at large-scale scraping where you need thousands of unique IPs but do not need persistent sessions. Dedicated proxies excel at account management, social media, and e-commerce where consistent IP identity builds trust over time.

Question 6

What is IP trust score and why does it matter?

Accepted Answer

IP trust score is a composite metric that platforms use to evaluate incoming traffic. Factors include: IP type (mobile > residential > datacenter), historical behavior on that IP, abuse reports, blacklist presence, and traffic patterns. Mobile IPs from real carriers typically score 90-99%, residential IPs 70-90%, and datacenter IPs 20-60%. Shared IPs degrade faster because multiple users' behaviors compound the negative signals.

Question 7

Can I use shared proxies for social media management?

Accepted Answer

It is not recommended. Social media platforms (Meta, TikTok, X, LinkedIn) actively track IP reputation and link accounts that share IPs. Using shared proxies for social media management means: other users may have already flagged the IP, your accounts can be linked to strangers' accounts, and any ban on the IP cascades to all connected profiles. Dedicated mobile proxies are the standard for social media work.

Question 8

How does ProxyStyler's model differ from shared proxy pools?

Accepted Answer

Most proxy providers — including major names like Bright Data (72M pool), Oxylabs (100M pool), and Smartproxy (65M pool) — operate shared IP pools where multiple customers rotate through the same addresses. ProxyStyler assigns a dedicated physical device with a real SIM card to each customer. Your device, your SIM, your IP history. No other customer ever touches your proxy infrastructure. This 1:1 dedication model eliminates IP contamination entirely.
