An IPv6 proxy routes your request through an IPv6-addressed exit on the datacenter network instead of a traditional IPv4 address. Each /64 block carries 2^64 -- about 18.4 quintillion -- usable addresses, so exits stay cheap and effectively inexhaustible. From $0.40/GB, pay as you go, datacenter-only.
IPv6 proxies are the KnoxProxy datacenter pool, addressed over IPv6 instead of IPv4. They cost less per GB ($0.40 vs $0.60) because IPv6 address space is effectively unlimited, but they only reach targets that accept IPv6 connections -- about 40-45% of major sites in 2026. Default to IPv4 whenever a target's support is unconfirmed.
Success rate, response time, and country count are measured on the datacenter network IPv6 exits run on.
Volume tiers apply automatically -- no sales call required.
| Monthly usage | Rate /GB | Saving |

| Pay as you go | $0.40 | -- |
| 500 GB+ | $0.30 | -25% |
| 1 TB+ | $0.23 | -42% |
| 5 TB+ | $0.17 | -58% |

Same gateway, same account -- only the exit address family changes.
| Network | Datacenter only |
| Addressing | IPv6 -- /64 blocks |
| Protocols | HTTP · HTTPS · SOCKS5 |
| Rotation | Per request, or static dedicated |
| Targeting | Country, state, city |
| Trust score | Low -- same as IPv4 datacenter |
| Auth | User:pass or IP allowlist |
Rotation and sessions work exactly like rotating datacenter proxies -- IPv6 only changes which address family the exit uses.
Point your client at the datacenter gateway and add one header to request an IPv6 exit. Everything else -- auth, geo targeting, retries -- works exactly like standard datacenter proxies.
# US datacenter exit, IPv6 addressedcurl -x "http://USER:PASS@gw.knoxproxy.com:8000" \ -H "x-kx-country: us" -H "x-kx-family: ipv6" \ "https://www.google.com/search?q=knoxproxy"# -> 200 | 44 ms | datacenter-ipv6 | usIPv4 has about 4.3 billion addresses in total, and nearly all of them are already allocated. IPv6 uses 128-bit addresses, so a single /64 block -- the standard subnet a provider carves out per gateway -- holds 2^64 addresses on its own: about 18.4 quintillion, or roughly 4.3 billion times more than every IPv4 address combined. Regional registries hand out /48 and /64 blocks for a nominal fee, and that abundance is what keeps IPv6 priced at $0.40/GB instead of $0.60/GB for standard IPv4 datacenter.
One /64 block alone holds roughly 4.3 billion times more addresses than the entire IPv4 internet combined.
Same account, same gateway, either address family -- pick per target instead of by default.
Check compatibility before switching a target over: look for an AAAA DNS record, or send one test request through each address family and compare.
| Target | Fit | Why |
|---|---|---|
| Google Search & SERP | BEST | Full IPv6 support on Google properties -- rotate through a /64 block for a fraction of residential cost. |
| Social & video platforms | BEST | YouTube, Facebook, and Instagram are IPv6-ready at the platform level -- volume pricing applies cleanly. |
| Ad verification | GOOD | Works well once you confirm the ad network resolves over IPv6 -- check the AAAA record first. |
| Bulk QA & permissive APIs | GOOD | Same cost logic as IPv4 datacenter, cheaper still -- ideal for your own infrastructure checks. |
| E-commerce & retail | WEAK |
IPv6 exits run across the same 50-country datacenter footprint -- there is no separate location list to manage.
An IPv6 proxy routes your request through an IPv6-addressed exit instead of IPv4. On KnoxProxy it's the same datacenter network as standard datacenter proxies -- same gateway, same account, same billing model -- just addressed from IPv6 space.
Address scarcity drives IPv4 pricing. IPv4 has about 4.3 billion addresses in total and most are already allocated. IPv6 gives every /64 block 2^64 addresses -- around 18.4 quintillion -- so registries allocate them cheaply, and that savings passes straight through: $0.40/GB versus $0.60/GB for standard IPv4 datacenter.
Free trial, no credit card. Confirm AAAA support on your target list, then switch address families with one header.
| Amazon-, Walmart-, and Target-style sites are largely IPv4-only or flag IPv6 subnets -- use IPv4 instead. |
Only if the target accepts IPv6 connections. As of 2026, roughly 40-45% of major websites fully support it -- Google, YouTube, and most large ad and social platforms do; most e-commerce sites like Amazon, Walmart, and Target still don't. Check for an AAAA DNS record before switching a target over.
Both, like standard datacenter. Rotate per request from the pool by default, or reserve a static dedicated exit when a workflow needs a consistent address.
Yes. HTTP, HTTPS, and SOCKS5 all work over the same credential pair as standard datacenter proxies -- SOCKS5 natively supports IPv6 addressing.
Lower. IPv6 exits carry the same trust profile as IPv4 datacenter -- fast and cheap, but datacenter-allocated blocks are easier for anti-bot systems to fingerprint than a real residential or mobile connection. Reach for residential or mobile when trust matters more than cost.
Yes. Your account isn't locked to one address family -- request an IPv6 exit for IPv6-ready targets and fall back to standard IPv4 datacenter, ISP, residential, or mobile for everything else, all on the same credentials.
A /64 block -- the standard allocation for a single gateway -- contains 2^64 addresses, about 18.4 quintillion. A larger /48 allocation holds 2^80, roughly 1.2 trillion times that. Either size is far more than any rotation schedule could exhaust.
