IPv6 is the new standard for IP addresses. As you may know, almost all of the older IP addresses (IP version 4, IPv4) have been issued. IPv6 is the solution to this problem and theoretically these addresses cannot run out.
All Hostbee servers are connected to an IPv6 connection in the data center. All our (name) servers are set up and active on IPv4 and IPv6.
