 The above mentioned aspects can in principle also be applied to IPv6. The difference between the two are, that IPv6 subnet masks are usually only entered as number of bits of the network, the so-called prefix. And IPv6 networks know hierarchical structures. While in IPv4 all subnets are equal in their position or importance, IPv6 can partition a subnet in further subnets. So when your ISP assigns you an IPv6 address, you are usually assigned an entire prefix, within which your hosts can select their IPs freely. As most users let their router's DHCP assign IPv6 addresses automatically to the hosts, that leaves you with little to do. But in principle you could use the delegated prefix and partition it into two or more further subnets. E.g. you are assigned a 64 bit prefix. That leaves you with a 64 bit address space, that you can freely use. You could then take another 2 bits from that, as part of the new prefixes of four subnets. That would still leave 62 bits for the hosts in each network and 66 bits for their prexif/network number. However, that's something your router would have to support. This is when you ought to really know what you are doing and what to use for the task. The above mentioned aspects can in principle also be applied to IPv6.
