SOCKS5 Proxy
Protocol-agnostic, authenticated and with remote DNS support: SOCKS5 is the most flexible standard in the proxy world. It also carries every kind of TCP traffic beyond the web.

What Is a SOCKS5 Proxy?
SOCKS5 is a proxy standard that carries traffic between client and server independently of the application protocol . While an HTTP proxy understands only web requests, SOCKS5 forwards incoming data without interpreting it: a web page, email, game connection or a custom TCP service — all can pass through the same SOCKS5 tunnel. This neutrality makes it the most versatile proxy type.
SOCKS4 vs SOCKS5
| Feature | SOCKS4 | SOCKS5 |
|---|---|---|
| Authentication | None | Username / password |
| UDP support | None | Yes |
| IPv6 support | None | Yes |
| Remote DNS resolution | Partial (4a) | Yes |
In short, SOCKS4 is a historical standard; every modern service you come across today uses SOCKS5.
SOCKS5 vs HTTP Proxy
Because an HTTP proxy understands the protocol, it can do caching and header management; SOCKS5, carrying the data as it is, is less intrusive and is the only option for non-web applications. In performance terms, SOCKS5 has lower protocol overhead. Detailed comparison: The Difference Between an HTTP Proxy and SOCKS5.
Authentication
One of the most valuable features of SOCKS5 is built-in username/password authentication. On paid packages your proxy access is protected in the ip:port:username:password format; not everyone who knows the address can connect, only those who hold the credentials. Free SOCKS5 addresses, on the other hand, are usually unauthenticated — which means addresses anyone can use, and therefore busier and less stable ones.
The Remote DNS Advantage
In SOCKS5, domain name resolution can be done on the proxy server ("remote DNS"). This way your DNS queries don't go to your own internet provider; your privacy improves and the risk of a DNS leak disappears. In Firefox, don't forget to tick the "Proxy DNS when using SOCKS v5" option.
TCP Use Cases
- Putting non-browser applications (messaging, FTP, email clients) behind a proxy
- Routing automation bots at the application level
- Services that need long-lived, persistent connections (websocket, streaming)
- Per-application proxy assignment in anti-detect browser profiles

Frequently Asked Questions
01Is a SOCKS5 proxy more secure than an HTTP proxy?
SOCKS5 does not encrypt traffic; security comes from encryption at the application layer (HTTPS, TLS). Its advantage lies in privacy-friendly features such as remote DNS and authentication.
02Which port does a SOCKS5 proxy use?
The standard port is 1080, but other ports can be used too. Enter the port shown in the list exactly as it is.
03Can I find a Turkey SOCKS5 proxy?
Yes. In the free list, set the Country filter to Turkey and the Protocol filter to SOCKS5 to see addresses located in Turkey. For guaranteed Turkey SOCKS5, look at the paid packages.
04Does my browser support SOCKS5?
Firefox supports it natively. Chrome can use SOCKS5 through the system proxy setting or through extensions. Most automation tools and HTTP clients also offer a SOCKS5 parameter.
05Is SOCKS5 used for UDP traffic?
The protocol supports UDP; however, not every server enables UDP relaying. For jobs that require UDP, check the protocol support stated in the package description.
