How IPv6 proxies work
You connect to the proxy over an ordinary IPv4 host and port, so any device or tool can use it. The proxy then reaches the destination from your own private IPv6 address. HTTP/HTTPS and SOCKS5 are accepted on the same port.
How to check IPv6 support
A website supports IPv6 if its domain has an AAAA record. You can look this up with any DNS lookup tool, or run dig AAAA example.com. If no IPv6 address is returned, requests through an IPv6 proxy to that site will fail rather than fall back to IPv4.
Short rentals
IPv6 proxies can be rented from 3 days, the shortest period in the shop, which makes them practical for quick tests and one-off jobs.
