Frequently Asked Questions
{ FAQ }What is a proxy in simple words?
Proxies are an intermediary between your device and the Internet. They hide your real IP address by replacing it with another one, which helps you maintain anonymity, bypass blockages, and speed up access to resources.
What is the difference between IPv4 and IPv6 proxies? Which is better?
IPv4: 32-bit addresses (e.g. 192.168.1.1), limited in number, supported by most sites.
IPv6: 128-bit addresses (e.g. 2001:0db8:85a3::7334), there are more of them, cheaper, but not all sites support them.
What to choose: IPv4 for versatility, IPv6 for economy and modern tasks.
What is the difference between HTTP(S) and SOCKS(4,5) proxy protocols? Which is better?
HTTP(S): Works only with web traffic (surfing, parsing, APIs).
SOCKS(4,5): Supports any type of traffic (web, games, video, P2P).
What to choose: HTTP for web, SOCKS5 for universal use.
What are public/free proxies?
These are proxies available to everyone for free. They are often slow, unreliable and insecure because they can be used by many users at the same time. Using such proxies is suitable only for simple tasks where speed and privacy are not important.
What are packet proxies?
Batch proxies are a group of proxies leased at once, such as 10, 50 or 100 IP addresses. They are suitable for bulk tasks, such as parsing or promotion, and allow you to spread the load across multiple addresses.
What are one-handed proxies and private/individual/exclusive/elite/dedicated proxies?
These are proxies that are leased by one user. No one else can use them during the rental period. They provide high speed, stability and privacy. Suitable for sensitive tasks such as working with accounts or payment systems.
