What is SOCKS4 and when do you need it?

SOCKS4 is the 1990s predecessor of SOCKS5: the same blind TCP tunnel — the proxy relays bytes without reading or modifying them — minus everything the fifth version added later. There's no username/password authentication, no UDP, no IPv6, and no remote DNS: your application resolves the hostname itself and hands the proxy a ready IPv4 address.

You need it in exactly one situation: software written before SOCKS5 support became universal and never updated since. Old Windows utilities, self-written bots, tools whose vendor disappeared years ago — none of them are worth rewriting while they still do their job. Before settling on version 4, though, dig through the tool's advanced settings: plenty of applications that claim to be SOCKS4-only actually support v5 and simply default to the older version for compatibility.

There's no separate SOCKS4 product to buy here — every IP in every package accepts SOCKS4, SOCKS5, HTTP, and HTTPS connections on the same port, at no extra charge. A legacy tool runs today, and when you replace it, you change one dropdown in its settings, not your proxy list. Specs are in the adjacent panel; pricing is in the calculator above.

# HTTP or HTTPS proxy

import requests

import { ProxyAgent } from "undici";

const dispatcher = new ProxyAgent("http://login:password@IP:port");
const res = await fetch("https://example.com", { dispatcher });
console.log(res.status);

$ch = curl_init("https://example.com");
curl_setopt($ch, CURLOPT_PROXY, "IP:port");
curl_setopt($ch, CURLOPT_PROXYUSERPWD, "login:password");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);

Fill in the credentials from your Dashboard. If you use IP whitelisting, you don't need a username or password.

I am thankful to the service creators for user-friendly interface. As for proxy-servers they are rather fast and of high quality.

DL Daniel Lytle October 2025

Prompt service, as well as a large number of different tariff plans. You can subscribe to several packages at the same time to use them via API. I bought unlimited proxies with rotation.

LJ Luke J January 2025

I took proxies for Ukraine. I need proxy servers for my social networks. The admins advised me how to use proxies effectively in order not to ban my accounts. The proxies themselves work well and the prices are as adequate as possible.

C Clark February 2025

KeyCollector started to ban free proxies. So I started looking for paid proxies. I compared prices and chose this service. I was looking for IPv4 proxies, they are a bit cheaper than the competitors. In general, I like everything, if there are any questions, the support immediately solves them. Very convenient!

Frequently asked questions

Can't find your answer? Message us in live chat — real humans reply.

My old bot only supports SOCKS4. Do I need a special SOCKS4 plan?

No — SOCKS4 is a connection mode, not a separate product. Every IP in a package answers over SOCKS4 on the same port that serves SOCKS5, HTTP, and HTTPS: enter ip:port in the bot and it runs. When you eventually replace the tool, switch its protocol setting to SOCKS5 — the list, the whitelisting rules, and the plan stay exactly as they were.

SOCKS4 has no password. What stops a stranger from using my proxies?

IP whitelisting — and it closes the gap the protocol left open. A bare SOCKS4 server is defenseless by design: there's no authentication in the protocol at all, so anyone who finds the address can route traffic through it. Our proxies respond only to source IPs you've added in the Dashboard — whitelisting is mandatory on every plan — so the missing password never comes into play. Add your machine's IP and that's the entire security setup; there's nothing to configure inside the protocol itself.

Why do some sites fail over SOCKS4 but work fine over SOCKS5?

Almost always DNS or IPv6 — SOCKS4 predates both. The client has to resolve the hostname itself and pass the proxy a ready IPv4 address, so if your application can't resolve the name locally, or the target only resolves to an IPv6 address, the connection dies before it starts. Some tools work around the DNS half with the SOCKS4a extension, which sends hostnames to the proxy, but client support for it is inconsistent. If a site works over SOCKS5, that's your fix: the same IPs, and version 5 resolves names on the proxy side — setup details are on the SOCKS5 page.

Why is SOCKS4 still around if SOCKS5 does everything better?

Because software outlives protocols. SOCKS5 has been the standard since 1996, yet tools written before their authors adopted it are still running in production in 2026 — and they keep SOCKS4 alive, not any technical advantage. The rule is short: new project — SOCKS5, always; a working legacy tool — SOCKS4 as its compatibility mode, on the same addresses, and nothing needs rewriting.
