All the projects I have ever worked on, the internal networks always were IPv4. Maybe because it is much simpler for humans to have an overview of the internal subnets in that way. Maybe IPv6 uses numbers that are too large for us.

The IPv6 addresses on my internal network look like fd7a::1, fd7a::2, etc. They are shorter than v4 addresses.
