SOCKS5 vs HTTP proxies: which one should you use?

Updated November 7, 2026 · 2 min read

Both carry HTTPS safely, but they work at different layers. When SOCKS5 is worth it, when HTTP is simpler, and what socks5h means for DNS leaks.

Most proxy plans give you both an HTTP and a SOCKS5 endpoint. For ordinary web scraping they behave almost the same. The differences show up with non-web traffic, DNS and some tools.

How they differ

  • HTTP proxy: speaks HTTP. For https sites the client sends a CONNECT request and the proxy opens a tunnel; the encrypted traffic passes through untouched. Plain http requests are forwarded by the proxy itself.
  • SOCKS5 proxy: works one level lower. It forwards raw TCP connections and does not care whether the traffic is HTTP, IMAP, SSH or a game protocol.

In both cases HTTPS stays end-to-end encrypted. Neither type lets the proxy read your https traffic.

Choose HTTP when

  • You only fetch websites and APIs.
  • Your tool only supports HTTP proxies. Many older libraries and some browser settings do.
  • You want the simplest setup: http://user:pass@host:port works almost everywhere.

Choose SOCKS5 when

  • You need protocols other than HTTP: mail clients, SSH, FTP, custom TCP apps or some games.
  • You want DNS resolved at the proxy side (see below).
  • An app explicitly asks for SOCKS, for example some messengers and torrent-style clients. Note that many residential pools do not forward UDP, so check before relying on it.

socks5 vs socks5h: the DNS detail

With socks5:// many clients look up the domain name on your own machine first and send only the IP to the proxy. That leaks the lookup to your local DNS resolver, and the site may get an IP chosen for your location instead of the proxy's. With socks5h:// (h for hostname) the proxy does the lookup. In curl, Python requests and most libraries, prefer socks5h.

curl -x socks5h://user:pass@host:port https://ipinfo.io/json

Speed

There is no meaningful speed difference for normal use. The proxy network, the distance to the gateway and the target site matter far more than the protocol.

Bottom line

Default to HTTP for the web, switch to SOCKS5 (with socks5h) for anything else or when DNS location matters. Most Proxare residential lines include both, and you choose the protocol when you generate your lines.
