IPv6 Datacenter Proxies

The highest-throughput, lowest-cost option in the catalogue at ~30 ms response, with unlimited bandwidth on the IPv6 stack (US). Built for high-volume operations on IPv6-compatible targets where cost-per-request is the primary lever.

Specs

Pool: ~160 octillion IPv6 addresses (US)
Coverage: US only (country-level targeting)
Typical response time: ~30 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: high-volume work on IPv6-compatible targets

Connect

Gateway: v6-dc.flashproxy.io — port 50 (HTTP) / 51 (SOCKS5).

# Rotating — a fresh IP on every request
curl -x "http://USERNAME:PASSWORD@v6-dc.flashproxy.io:50" https://api.ipify.org

# SOCKS5
curl -x "socks5://USERNAME:PASSWORD@v6-dc.flashproxy.io:51" https://api.ipify.org

Request parameters

IPv6 Datacenter 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:PASSWORD@v6-dc.flashproxy.io:50" https://api.ipify.org

# Sticky — hold the same IP for 30 minutes
curl -x "http://USERNAME-time-30-session-a1b2c3d4:PASSWORD@v6-dc.flashproxy.io:50" https://api.ipify.org

Sessions

Use rotating for maximum IP diversity or sticky to keep the same IP across a session — see Rotating & sticky.

Pricing
