IPv6 vs IPv4 VPS

Having trouble connecting to your IPv6 only VPS? If so, then the information contained below is intended to help you establish connectivity.

What is IPv6? What do I care?

The internet largely runs upon a 32-bit (IPv4) addressing scheme, and there's simply not enough internet addresses for everyone. As a result, IPv6 or IP version 6 is the next generation Internet protocol that will eventually replace the internet's legacy IPv4 protocol.

While an increasing number of sites now support IPv6 alongside the legacy IPv4 protocol, some sites may still only support IPv4.

To help you transition to, test and experiment with, and use in a production capacity, we provide native IPv6 support for all VPS environments. These can either run alongside your existing IPv4 addresses1), or you can order a VPS that has only IPv6 addresses assigned.

Can I use IPv6 today?

IPv6 has been in active production deployment since June 2006, when organized worldwide testing and evaluation efforts ceased.

IPv6 is endorsed and implemented by all Internet technical standards bodies and network equipment vendors. It encompasses many design improvements, including the replacement of a 32-bit IPv4 address format with a 128-bit address, for a capacity of about 3.4×1038 addresses.

How do I connect to my IPv6 only VPS?

If your internet provider supports and supplies globally routable IPv6 addresses, then connecting to your VPS from any modern operating system is as easy as using your VPS's IPv6 address in the “hostname” or “address” field of whatever connecting tool you're using.

If your internet provider does not support IPv6, then you will need to establish an IPv4 to IPv6 tunnel. Hurricane Electric has excellent resources to get you started with this exciting internet evolution.
