SOCKS5

Ensure you are using advanced parameters directly in the proxy username to specify the location and keep the IP from rotating with residential and mobile proxies. Refer to the Common Issues section below to learn how.

SOCKS5

Residential and Mobile Proxy Support Limitations
The gate.decodo.com endpoint and the 7000 port must be used to utilize SOCKS5 Residential or Mobile proxies. Country endpoints, such as us.decodo.com, will not function!You can target specific locations instead by specifying the location in your username using advanced parameters:
  • e.g.: user-username-country-us will connect to the USA pool.
To get a sticky SOCKS5 Residential or Mobile proxy in a tool, you must use a session parameter. Otherwise, the proxy will always rotate even with a set sessionduration parameter.
  • e.g.: user-username-session-abc123-sessionduration-30 will connect to the same session.
    • The session ID name can be defined by any string of your choice.
Learn more in our advanced parameter guides for Residential and Mobile proxies.

​
Direct IP

If you buy an IP list, you can specify which IPs to connect to using the direct ip parameter in the proxy username: user-username-ip-x.x.x.x
  • Supported products: DC Pay/IP, Dedicated DC, ISP Pay/IP, Dedicated ISP plans.
  • Products that offer access to the full proxy pool, such as residential proxies, do not support this parameter.
  • Decodo proxies don’t support an IP:PORT format by default.
  • You must use the endpoint rotator format (e.g., us.decodo.com:10101).
  • If necessary, try the workaround here, but it only works temporarily before requiring another setup update.
