US IPv6 Proxies at Octillion Scale
FlashProxy IPv6 proxies are US-based and come in two variants — IPv6 Residential and IPv6 Datacenter — backed by roughly 320+ octillion total addresses, 30–39 ms typical response, and per-GB pricing low enough to scale freely.

Why US IPv6 Proxies
IPv6's defining advantage is sheer address space. FlashProxy's US-based pool spans roughly 320+ octillion addresses total — about 160 octillion per variant — which means you almost never reuse an IP and rarely land on one a target has already seen. That abundance translates directly into cost: IPv6 Datacenter starts at $0.28/GB and scales down to $0.055/GB, while IPv6 Residential runs $0.42/GB down to $0.065/GB. For high-volume work against US destinations, that combination of vast diversity and low per-GB cost is hard to match with IPv4.
Two Variants: Residential vs Datacenter
FlashProxy offers IPv6 in two flavors. IPv6 Residential addresses carry a residential trust profile, which helps when a target scrutinizes the origin of a connection. IPv6 Datacenter addresses prioritize consistent throughput and the lowest per-GB cost, starting at $0.055/GB. Choose Residential when IP classification and trust signals matter most; choose Datacenter when raw performance and cost efficiency are the priority. Both are US-based and share the same protocol support, so you can mix them across a project as each task demands.
Your Target Must Support IPv6
This is the one constraint to plan around: IPv6 proxies can only reach IPv6-enabled destinations. If a site or API is served only over IPv4, an IPv6 proxy cannot connect to it. Many large platforms publish AAAA DNS records and are reachable over IPv6, but plenty of sites remain IPv4-only. Before committing a workflow to IPv6 proxies, confirm your target resolves over IPv6 — a quick AAAA-record lookup tells you. Where targets are IPv6-ready you get the full benefit of the address space; where they are not, IPv6 simply will not apply.
Performance and Scale
Typical response times run 30–39 ms, keeping the proxy layer light enough for latency-sensitive tasks. The real story is scale: with about 160 octillion addresses per variant, you can spread requests across an effectively inexhaustible IP space without exhausting it. Time-based tiers include unlimited bandwidth, so long-running jobs and sustained traffic do not inflate costs unpredictably. That makes the network suited to large crawls, continuous monitoring, and any US workload that needs both speed and breadth.
Setup
Connection is standard host:port with user:pass authentication, so the proxies drop into existing tooling without custom code. Both HTTP and SOCKS5 are supported, and SOCKS5 includes UDP ASSOCIATE — meaning UDP-based traffic can be proxied directly rather than forced over TCP. Point your client at the endpoint, supply your credentials, and choose the variant that fits the job. The same credentials work across HTTP and SOCKS5, so you can switch protocols per task without reprovisioning.
Pricing
Pricing scales with volume on both variants. IPv6 Residential starts at $0.42/GB and drops to $0.065/GB at the highest tiers. IPv6 Datacenter starts at $0.28/GB and drops to $0.055/GB. Time-based plans add unlimited bandwidth, which suits sustained or unpredictable traffic where a fixed per-GB model would be hard to budget. Because both variants share the same US pool and protocol support, you can route trust-sensitive requests through Residential and high-volume throughput through Datacenter to balance cost against IP profile.
