4.8What Is a Proxy Server and How Does It Work?
A proxy is an intermediary server between two devices on a network. When you use proxies, your internet requests are routed via proxy server before they reach the website or service you want to access. As proxies hide your IP address, they allow you to bypass website restrictions and keep your online activity private.
How does a proxy server work?

When you use a proxy, all of your requests are first sent to the proxy server. Then, the proxy connects to the website or service on your behalf to request the data. The website sends the data back to the proxy, which then passes it to you. All while using a different IP address to keep your real identity hidden.
Residential proxies
Mobile proxies
Shared datacenter proxies
Dedicated datacenter proxies
What is it?
Residential IP addresses are real mobile or desktop devices that pinpoint a certain physical location.
Mobile IPs are virtual IPs from real mobile devices. These are connected to mobile carriers and run on mobile networks, which makes them the most successful among all proxy types.
Shared datacenter proxies are virtual IP addresses sourced at powerful data centers.
Dedicated datacenter proxies are datacenter proxies that belong to only you.

HTTP(S) proxies
HTTP and HTTPS are protocols for data transmission over the net. Use HTTP(S) proxies to stay safe from harmful content and malware, save traffic by recognizing and bypassing ads, and access geo-restricted websites.

SOCKS5 proxies
SOCKS5 is a versatile protocol that handles various types of traffic, such as TCP, UDP, SMTP, and FTP. SOCKS5 proxies are used for use cases, like multiple accounts management, cyber and brand security.

Anonymous proxies
This type of proxy servers hides your identity by not revealing your IP address and making all of the requests on their behalf. Anonymous proxies provide a high level of anonymity, privacy, and security.
Transparent proxies
Differently from an anonymous proxy, a transparent proxy server doesn’t hide the user's IP; in addition, it doesn’t modify requests. This kind of proxy servers is commonly used for caching and content filtering.

3G/4G/5G proxies
3G/4G/5G mobile proxies are IP addresses coming from real mobile devices connected to the internet via mobile data. They hide your real IP, allow you to bypass geo-restrictions and blocks, and are highly successful among all proxy types.

IPv4 & IPv6 proxies
IPv4 proxies use an IPv4 protocol, and IPv6 proxies use a newer IPv6 protocol to mask your real IP address. However, both of the types are used to provide anonymity and privacy, and access any website you need.

Rotating proxies
Rotating proxy servers change an IP address with a new one with every connection, which makes it harder for websites to track and block the IP used. It allows to avoid IP blocks and CAPTCHAs.

Unlimited proxies
Unlimited proxies let you enjoy unlimited bandwidth usage. They can become very handy when you’re planning to use a large amount of traffic, for example, when streaming, or playing games.

Shared proxies
Shared proxies allow sharing the same IP pool with multiple users. It lets you enjoy the top-notch proxy server quality, create successful connections – all at affordable prices.

Dedicated proxies
Each dedicated proxy, aka private proxy, refers to a proxy type that is used only by one user at a given time. It gives you full control and ownership of the browsing history, acceptability, and health of your IPs.

Frequently asked questions
How does a proxy work?
If you use a proxy, your connection goes through a proxy server. In other words, when you try to access a certain website, your connection request doesn’t go directly to the website. It first goes to a proxy server, which then forwards your request to the website you’re trying to reach. This way, your real IP address stays anonymous but you’re still able to access the information you need on that website.
What are the advantages of using a proxy server?
If you want to increase your privacy, gather data, manage multiple accounts, crack firewalls, or access location-specific content, it’s impossible to do all that from a single IP address. Using a proxy server enables you to use multiple IPs to access information from all over the world without restrictions.
What is the main function of a proxy?
The main reason why proxies were created was to hide your real IP address so that you could stay anonymous whether it would be for personal or professional use.
Is a proxy better than VPN?
Both VPN and proxies hide the IP address of your device. Unlike VPN, a proxy server doesn’t encrypt your traffic. This is the key reason why proxies are generally faster than VPN. As a result, using a proxy will let you enjoy better download/upload speeds when compared to VPN.

What should I consider before buying proxies?
We’ve drawn up this handy checklist so that you’d know what you should pay attention to before choosing proxies:
- Traffic – think about how much traffic you’re gonna need so that it’d be easier to decide what pricing model (based on traffic or the number of requests) would suit you most.
- Proxy pool size – check how many IP addresses are on offer and what the quality of those IPs is. Think of some extra details too, e.g. proxy speed.
- Locations – do you have access to country- or city-specific ports, or both? How many countries does a proxy network cover?
- Pricing – don’t get easily seduced by free proxies as they possess some cybersecurity risks and perform poorly. Always look for reasonably-priced proxies from reliable providers.
- Customer support – make sure your proxy provider has unwavering customer support in case you run into any trouble.
