What Is a Proxy Server?
A proxy server sits between your computer and the websites you visit. Instead of connecting directly, your request goes to the proxy first, which forwards it on your behalf using its own IP address. The destination site sees the proxy's IP — not yours.
Think of it as a middleman. You ask the middleman to fetch something, and the store never knows who actually placed the order. This simple concept powers everything from corporate security to large-scale web scraping.
How Do Proxies Work?
When you configure a proxy, your device sends requests to the proxy server instead of directly to the target website. The proxy evaluates the request, forwards it to the destination, receives the response, and passes it back to you. The entire round-trip takes milliseconds on a fast proxy like those offered by Botosaur.
Most proxies operate at the application level (HTTP/HTTPS) or the transport level (SOCKS5). HTTP proxies understand web traffic and can modify headers, while SOCKS5 proxies handle any type of traffic — including gaming, streaming, and P2P.
Types of Proxy Servers
By Source
- Residential proxies — IPs assigned by real ISPs to homeowners. Hardest to detect and block.
- Datacenter proxies — IPs from cloud hosting providers. Fast and affordable, but easier to fingerprint.
- ISP proxies — The best of both worlds: datacenter speed with residential-level trust. Botosaur specializes in these.
By Function
- Forward proxies — Sit in front of clients, masking their identity from servers.
- Reverse proxies — Sit in front of servers, handling load balancing and caching for websites.

Common Use Cases
Proxies aren't just for tech enthusiasts. Businesses and individuals rely on them daily for:
- Web scraping and data collection — Rotate IPs to gather pricing data, search results, or market intelligence without getting blocked.
- Social media management — Run multiple accounts safely by assigning each account a unique IP.
- Ad verification — Check that ads display correctly across regions.
- Gaming and botting — Reduce latency, bypass geo-blocks, or run multiple game clients.
- Privacy and anonymity — Hide your real IP from trackers and data brokers.
Proxy vs VPN: A Quick Comparison
Both tools mask your IP, but they work differently. A VPN encrypts all device traffic through a tunnel, making it ideal for personal privacy. A proxy routes specific application traffic through an intermediary, giving you finer control — especially for automation and multi-account setups.

Our recommendation: If you need per-application control, high speed, and the ability to use multiple IPs simultaneously — proxies are the way to go. Botosaur's ISP proxies give you residential-grade trust at datacenter speeds, with plans starting at just a few dollars per month.

Frequently Asked Questions
What is a proxy IP address?
A proxy IP address is the IP that websites see when you connect through a proxy server. It replaces your real IP address, making it appear as though your traffic originates from a different location or device.
Is using a proxy legal?
Yes, using a proxy is legal in most countries. Proxies are standard business tools used for security, privacy, and data collection. However, what you do through a proxy must still comply with applicable laws and terms of service.
Do proxies slow down internet speed?
Quality proxies add minimal latency — often less than 10 milliseconds. Datacenter and ISP proxies like those from Botosaur are especially fast. Free or overloaded proxies, on the other hand, can significantly slow your connection.
What is the difference between a proxy and a VPN?
A proxy routes traffic from a specific application through an intermediary server. A VPN encrypts and routes all traffic from your entire device through a secure tunnel. Proxies offer more granular control; VPNs offer broader encryption.
Are proxies safe to use?
Proxies from reputable providers like Botosaur are safe. Avoid free proxy lists, which may log your traffic or inject ads. Always use proxies that support authentication and come from a trusted source.
What is a residential proxy?
A residential proxy uses an IP address assigned by a real Internet Service Provider to a household. These IPs are highly trusted by websites because they look like regular home users browsing the internet.
What is SOCKS5?
SOCKS5 is a proxy protocol that handles any type of internet traffic — not just HTTP. It supports UDP and TCP, making it suitable for gaming, streaming, torrenting, and other non-web applications.
How much do proxies cost?
Proxy pricing varies widely. Datacenter proxies can cost as little as $1-2 per IP per month. ISP and residential proxies typically range from $2-10 per IP per month depending on quality and features. Botosaur offers competitive ISP proxy plans — check our pricing page for current rates.
