Residential IPv6

This guide shows you how to set up a residential IPv6 proxy on ColdProxy's USA-only IPv6 network. You buy a Mbps speed tier, the plan includes a /32 subnet, and sticky sessions can hold an IP indefinitely. It connects over the same per-service gateway as every ColdProxy plan, with one critical prerequisite: your target must publish IPv6 addresses or be served by a supported CDN. The steps below cover authentication, the gateway endpoint and ports, the reachability caveat, and how to verify your exit IP. The full product overview lives at /proxy/residential-ipv6/, and current speed-tier pricing is on the Residential IPv6 pricing page.

#What you are buying

Residential IPv6 is a speed-tiered residential proxy product on the IPv6 address family. You choose a throughput tier in Mbps, the plan includes a /32 subnet of residential IPv6 space, and coverage is United States only. Sticky sessions can be held from 5 seconds up to FOREVER, which suits long-lived workflows that need a stable IP.

#Check IPv6 reachability before you buy

The plan includes CDN-aware IPv6 reachability: for supported CDN-fronted domains (for example sites behind Cloudflare, Akamai, Fastly, or Amazon CloudFront) that publish no AAAA record of their own, ColdProxy's CDN-aware reachability keeps supported requests on IPv6, even without a published AAAA record. See IPv6 reachability for how to diagnose targets.

#Connection details (residential IPv6 proxy setup)

Residential IPv6 connects through its own per-service gateway:

gw-2312.coldproxy.com

2312 is the service/package ID of the plan you purchased. Use any port in the 30000–34999 range (30000 in the examples). HTTP, HTTPS, and SOCKS5 run on the same gateway and are auto-detected. The canonical proxy string is:

gw-2312.coldproxy.com:30000:USERNAME:PASSWORD

Most clients also accept USERNAME:PASSWORD@gw-2312.coldproxy.com:30000. See How to Connect and Authentication for the full reference.

#Connect example

Use an IPv6-capable echo endpoint to confirm you are exiting over IPv6:

curl -x "http://USERNAME:PASSWORD@gw-2312.coldproxy.com:30000" \
  "https://api6.vipv6proxy.com/api/checker/my-ip"

import requests

proxy = "http://USERNAME:PASSWORD@gw-2312.coldproxy.com:30000"
proxies = {"http": proxy, "https": proxy}

# This endpoint returns an IPv6 address when the request exits over IPv6
resp = requests.get("https://api6.vipv6proxy.com/api/checker/my-ip", proxies=proxies, timeout=30)
print(resp.json())

Confirm IPv6 reachability, the exit IP, and location with Proxy Checker and My IP.

#Geo-targeting and sessions

Coverage is USA only, so country-level targeting is not the point of this plan; the value is the included /32 subnet of US residential IPv6 address space. Under User:Pass auth, the username tag scheme controls session behavior, and sticky sessions can be held from 5 seconds to FOREVER. A timed sticky session uses -session- and -time-; the FOREVER hold is the -identifier- pin shown below, not a -time- value:

curl -x "http://user-session-481516-time-2h:PASSWORD@gw-2312.coldproxy.com:30000" \
  "https://api6.vipv6proxy.com/api/checker/my-ip"

For a deterministic, stateless IP pin (the same identifier always maps to the same IP, with no session lifetime to manage), use -identifier-. This is the username format the client area generates, where USERNAME is your service username and the identifier value stays as issued; see IP pinning on IPv6 plans:

curl -x "http://USERNAME-identifier-mq8hhadw1mbdj50:PASSWORD@gw-2312.coldproxy.com:30000" \
  "https://api6.vipv6proxy.com/api/checker/my-ip"
