IPv6 Residential Proxies
IPv6-allocated residential IPs (US) with strong ~39 ms response times — built for sites that have shifted to IPv6-first infrastructure and operations that benefit from the larger address space.
Specs
- Pool: ~160 octillion IPv6 addresses (US)
- Coverage: US only (country-level targeting)
- Typical response time: ~39 ms
- Protocols: HTTP, SOCKS5 (SOCKS5 UDP ASSOCIATE supported)
- Sessions: rotating or sticky (up to 2 hours)
- Concurrency: up to 50,000 concurrent connections (per-GB); 9,000 on the time-based Unlimited tier — higher on request
- Best for: IPv6-first targets and large-address-space operations
Connect
Gateway: beta-ipv6.flashproxy.io — port 30 (HTTP) / 31 (SOCKS5).
# 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
IPv6 Residential 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 | see Geo-targeting | — | Target one exact IPv6 address from the pool |
For the complete reference — every accepted value — see the API reference.
Examples
# Rotating — a fresh IPv6 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.orgSessions
Use rotating for maximum IP diversity or sticky to keep the same IP across a session — see Rotating & sticky.
