SOCKS5 Proxies
SOCKS5 is a protocol, not a proxy type: it relays TCP and optionally UDP traffic for any application, not just web browsers, and supports username and password authentication. Residential, mobile, ISP and datacenter proxies can all be offered over SOCKS5, so compare the underlying IP type first, then whether UDP, IP allowlisting and simultaneous HTTP access are included.

Buyer guide
- Decide the IP type you need first; SOCKS5 support alone says nothing about IP quality.
- Confirm UDP support if your application uses it, since many SOCKS5 offers are TCP only.
- Check that DNS is resolved on the proxy side if you need location-accurate lookups.
- Verify the authentication methods work with the software you plan to connect.
What to compare
- 01Underlying proxy type
- 02UDP support
- 03Authentication: user/pass vs IP allowlist
- 04HTTP and SOCKS5 on the same port
- 05DNS resolution: local vs remote
- 06Locations and allocation
Use cases
- Routing non-browser applications
- App and client testing by geo
- Proxying tools that lack HTTP proxy support
FAQ
Is SOCKS5 more secure than an HTTP proxy?
Not inherently. SOCKS5 does not encrypt traffic by itself; security depends on the application using TLS. Its advantage is that it works with more protocols and applications.
What is the difference between SOCKS5 and SOCKS5h?
With SOCKS5h the hostname is resolved by the proxy rather than your machine, which avoids local DNS lookups and returns results for the proxy's location.
Can one proxy plan support both HTTP and SOCKS5?
Many sellers expose both protocols on the same IPs, sometimes on different ports. The listing's protocol field shows what is included.
