Parameter Input Guide - Unlimited Residential Proxies
Last updated: 2026-09-10 13:43:36
i) Definition of Parameter Input
Parameter Input means appending one or more parameters after a fixed part of the connection string so the proxy behaves the way you need. To obtain customized IPs, follow the basic rules below.
ii) Definition of Parameters
| Parameter | Description |
|---|---|
| acc | Authentication account (username starts with acc-). Required. |
| cnt | Continent code (e.g. EU, NA, AS). Default: global mix. Required. |
| sid | Sticky session ID: keeps the egress IP stable. Up to 16 alphanumeric characters (case-sensitive). |
| ttl | Sticky duration in minutes (integer 3–60). Only applies when sid is present. |
iii) How to Input Parameters
Append -{key}-{value} segments after the username (before the password), in the form:
acc-username:password@host:port
Default configuration example
Without extra parameters, configuration looks like:
acc-username:[email protected]:60005
Example: sticky IP in Asia (AS), 10 minutes
acc-username-cnt-AS-sid-pgpqssqbzag8ws8-ttl-10:[email protected]:60005
cURL examples
Continent only (cnt-AS):
curl -U "acc-username-cnt-AS:password" -x "xxxx.du.utaproxy.com:60005" "https://ipvibe.com/ip" -L
Sticky session + ttl (keep one IP for a fixed duration, e.g. 3 minutes):
curl -U "acc-username-sid-blsfjjsl-ttl-3:password" -x "xxxx.du.utaproxy.com:60005" "https://ipvibe.com/ip" -L
All parameters shown together (continent, sticky session, ttl):
curl -U "acc-username-cnt-AS-sid-blsfjjsl-ttl-3:password" -x "xxxx.du.utaproxy.com:60005" "https://ipvibe.com/ip" -L
Replace acc-username, password, host, and port with your real credentials and endpoint.
