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.
