Proxy IPv6
Un proxy que enruta el tráfico a través de direcciones IPv6, ofreciendo pools enormes y baratos pero limitado a destinos compatibles con IPv6.
Un proxy IPv6 enruta tu tráfico a través de una dirección IPv6 en lugar del IPv4 más antiguo. Como el espacio de direcciones IPv6 es astronómicamente grande, los proveedores pueden ofrecer pools enormes de direcciones IPv6 muy baratos - a menudo por una fracción del coste de las escasas direcciones IPv4.
La pega es la compatibilidad. Un sitio de destino debe admitir IPv6 para que un proxy IPv6 pueda alcanzarlo. Muchos sitios grandes lo hacen (Google, Facebook y otros son de doble pila), pero muchos sitios son solo IPv4, y un proxy IPv6 simplemente no puede conectarse a ellos. Esto limita dónde son útiles los proxies IPv6.
También hay un matiz de reputación. Como los bloques IPv6 son tan grandes y baratos, algunos sitios tratan los rangos IPv6 -especialmente grandes bloques contiguos de un proveedor- con más sospecha, o aplican límites por subred /64 en lugar de por dirección. La abundancia que hace barato el IPv6 también puede facilitar su fingerprinting.
Los proxies IPv6 encajan bien en tareas de alto volumen contra destinos compatibles con IPv6 donde el coste por IP importa más. Para máxima compatibilidad y confianza en todos los sitios, los proxies residenciales o móviles IPv4 siguen siendo la opción por defecto más segura. Comprueba si tus destinos concretos admiten IPv6 antes de comprometerte.
Why IPv6 is cheap and where that stops mattering
IPv4 ran out. There are about four billion addresses in the protocol, the last blocks were handed out years ago, and what circulates now is a resale market where a single address costs real money every month. IPv6 has more addresses than anyone will ever need, so a provider can hand out a block the size of the entire IPv4 internet without noticing.
That is the whole reason an IPv6 proxy costs a fraction of an IPv4 one. It is not worse hardware or a worse network. It is an address space nobody has to ration.
The catch is on the other side. Your proxy speaks IPv6 to the destination, so the destination has to speak IPv6 too, which means it needs an AAAA record in DNS. Most large sites have one. A great many mid-size sites, and a surprising number of APIs, still do not, and against those an IPv6 proxy simply cannot open a connection.
There is a second, subtler issue. Because IPv6 blocks are enormous and cheap, abusers use them at scale, and some sites treat an entire /64 or /48 as one entity. Where an IPv4 ban hits one address, an IPv6 ban can hit every address you own in that block.
What we sell and where it works
IPv6 addresses are static and dedicated, delivered on the same ports as our other static products:
Check your target before buying in bulk
# Does the target have an AAAA record at all?
dig AAAA example.com +short
# If that returns nothing, IPv6 will not reach it.
# Test one address against the real target first:
curl -6 -x http://login:password@[your-ipv6]:50100 https://example.com -o /dev/null -w '%{http_code}\n'
# $0.20 per address per month, 17 countries- Buy one and test it against your actual target list before buying a hundred. The price makes bulk purchase tempting, and the AAAA requirement makes it wasteful when the targets are not ready.
- Coverage is 17 countries rather than the 41 we offer on IPv4, because the upstream stock is thinner.
- Traffic is unmetered, as on all our static addresses, so a working IPv6 setup is the cheapest sustained bandwidth we sell.
- If a target blocks one of your addresses, test a second from a different block before assuming the whole purchase is burned.
Where IPv6 disappoints people
Cheap does not mean equivalent
An IPv6 address only reaches IPv6-capable destinations. That is a hard technical limit, not a quality difference.
Dual-stack does not mean automatic
A site with both A and AAAA records is reachable, but your client decides which to use. Force IPv6 in testing, or you will measure an IPv4 path and conclude the proxy works.
Block-level bans
Sites that ban by prefix take out neighbouring addresses you also own. Spreading purchases across blocks costs nothing extra and limits the damage.
Not a substitute for residential
IPv6 addresses come from hosting infrastructure. Anything that rejects datacenter ranges rejects these too.
