IPv6 is the latest version of IP, which is of course still under development. And it should be noted that the use of Biznet IPv6 Tunnel Broker will bypass the security features/firewalls on existing IPv4 routers/firewalls, by connecting the end system directly with the IPv6 Internet. Where IPv6 on the client firewall system software and security features are relatively still in the early stages of development for some end systems.
Therefore, if you do not feel comfortable using IPv6 at this time, then customers are not required to use IPv6 in their services.
Customers will not be charged for using IPv6 access in Biznet services.
