# Rotating — a fresh IP on every request
curl -x "http://USERNAME:[email protected]:30" https://api.ipify.org# SOCKS5
curl -x "socks5://USERNAME:[email protected]:31" https://api.ipify.orgRequest parameters
Shared ISP (US) is US-only, so there's no country parameter to set. Two options are still available, encoded into the username:
| Parameter | Format | Example | Notes |
|---|---|---|---|
| Sticky session | time-<minutes>-session-<id> | time-30-session-a1b2c3d4 | Up to 120 min; omit for a rotating IP |
| Pin a specific IP | -ip-<address> | -ip-0_0_0_0 | Target one exact IP from the pool — see Geo-targeting |
For the complete reference — every accepted value — see the API reference.
Examples
# Rotating — a fresh US IP each request
curl -x "http://USERNAME:[email protected]:30" https://api.ipify.org# Sticky — hold the same IP for 30 minutes
curl -x "http://USERNAME-time-30-session-a1b2c3d4:[email protected]:30" https://api.ipify.org# Pin one exact IP
curl -x "http://USERNAME-ip-0_0_0_0:[email protected]:30" https://api.ipify.orgSessions
Use rotating for maximum IP diversity or sticky to keep the same IP across a session — see Rotating & sticky.
