IPv6 proxies are addresses of the new internet standard, hosted on servers in a data center. There are incomparably more addresses of this type than IPv4, so they are noticeably cheaper — this is their main advantage.
The main thing to check before purchasing
IPv6 only works with websites that support this standard. If a resource does not support it, connecting to it via IPv6 proxies will not work — this is not a malfunction, but a feature of the protocol. Therefore, compatibility should be checked in advance: how to do this is described in the article How to check if a website supports IPv6.
How the connection is arranged
The order has one common IPv4 address — a gateway, and each of your IPv6 addresses is accessible through its own port on this gateway. Therefore, each proxy has its own port number, and there is no common port for all addresses in IPv6.
Unlike other formats, the protocol is chosen when placing an order: "HTTP/S" or "SOCKS5". The authentication method is also set when ordering — "Username & Password" or "Static IP". The login and password are common for the entire account: the same for all your orders and all formats.
Where to find the address, port, and login details — in the article Where to find proxies, ports, and authorization data for IPv6.
Addresses are issued as a whole order
IPv6 is purchased as a set, and the minimum order is 10 addresses. A smaller quantity cannot be taken: this is a feature of the format, not a tariff limitation.
All addresses of one order have the same term. Therefore, they are grouped by orders in the list, and renewal, replacement, and auto-renewal apply to the entire order — it is impossible for a single address. More details — in the article Why the IPv6 list is grouped by orders.
What you pay for
Payment is for addresses and rental term: the traffic volume does not affect the cost. But traffic is not unlimited: the load is limited by the Fair Usage Policy — by default, this is 100 simultaneous connections per address. More details — in the article Fair Usage Policy: what it is and how it works.
You choose the country when ordering in the "Location" field; how to place an order is described in the article How to place an order for IPv6.
The 100% Uptime option is not available for IPv6 — it is only available for IPv4 and ISP formats.
What happens with the rental term
Three days before the rental ends, the proxies receive the status "Ends", and their number is displayed on the tile "Term ends IP". The rental can be renewed manually or auto-renewal can be enabled — both apply to the entire order. If the address is not suitable, a replacement request can be made.
