## TL;DR
IPv6 is a solution to the address sparsity in legacy IP (IPv4).
Only if you remove legacy IP, you really profit from IPv6.

The good news is, this has become rather easy nowadays.

For a good reason, because they want to reduce complexity. And costs,
obviously.
While there might be situations in which dual stack is required, in
general
* dual stack is more complex
* dual stack does not remove the costs
* dual stack almost always can be replaced by IPv6 only plus a gateway
translator
Even if you are not using public IPv4 space, you can still save costs
with going IPv6 only: whenever you connect to a VPN, whenever
companies merge networks, even [when you only run
docker](../how-ipv4-stops-me-from-working-in-the-train/):
with [private ip addresses](https://en.wikipedia.org/wiki/Private_network) you can
easily run into overlapping addresses. This costs time and in the end
resources.

and have it reachable from IPv6 and the legacy Internet:
you can either [create an IPv6 only virtual
machine](../ipv6-only-hosting/), setup a webserver on it and use the
[IPv4 to IPv6 proyx](../ipv4-to-ipv6-proxy/).
Or, if you want to have it much easier, you could go with
[IPv6 enabled webhosting](../zerocarbon-webhosting-with-ipv6/)

subtitle: Make your IPv6 resources reachable from the IPv4 world

description1:
## Introduction
The IPv4-to-IPv6 proxy allows your IPv6 only resources to be reachable
from the legacy IP (IPv4) Internet. It supports the following
protocols:
* HTTP
* HTTPS
* IMAPS
## When to use the IPv4-to-IPv6 proxy?
If you have a website that is running on an IPv6 only webserver, you
can use this service to enable access from the IPv4 Internet to it.
It can be used with [IPv6onlyhosting.com](../ipv6-only-hosting) VMs or
other IPv6 only services in the Internet.
## Pricing
The IPv4-to-IPv6 proxy is free for up to 10 domains per VM for VM
customers.
* Up to 10 domains (for non VM customers): 5 CHF/month (0.5 CHF/domain)
* Up to 100 domains: 30 CHF/month (0.3 CHF/domain)
* Up to 1000 domains: 100 CHF/month (0.1 CHF/domain)
* Above 1000 domains: on request
The pricing includes traffic.
