The second IPv6 option uses unique local addresses, which work more like the IPv4 private addresses. Companies that do not plan to connect to the Internet, and companies that plan to use IPv6 NAT, can use these private unique local addresses. The following lists summarizes these points for quicker review:

So theoretically it shouldn't be necessary to have private IPv6 addresses like the 192.168.x.x and 10.x.x.x addresses in IPv4. However until you can actually get an IPv6 address range from your ISP, you may want to use "private" addresses for internal networks and testing etc. Basically, without private IP addressing, we would have run out of IPv4 addresses many years ago. There simply are not enough IPv4 addresses to for everyone to have a unique IPv4 address, which was the original premise of IP. To restore this premise and the end-to-end nature of IP, the IETF created IPv6.

HTTP/HTTPS A /64 provides a mind bogglingly huge number of potential addresses. 2^64 worth! That's four billion IPv4 Internet's worth of IP addresses. (2^64 == 2^32 * 2^32. Four billion times four billion .) While the nature of IPv6 autoprovisioning reduces the actual number of addresses that need scanning, scanning it is still infeasible.

A virtual private server (VPS) is created through the process of virtualization, by which a virtual replica of a physical server is created. VPS is for hosting websites and/or software applications, particularly web based ones. Unlike shared hosting, this data is isolated on a single virtual machine, with resources solely dedicated to its user.

IPv4 Private Address Space and Filtering According to standards set forth in Internet Engineering Task Force (IETF) document RFC-1918 , the following IPv4 address ranges are reserved by the IANA for private internets, and are not publicly routable on the global internet:
