There isn't! (!)
Because IPv6 is a very, very (very) much larger IP addresses space, you don't need "private - aka non-routable - IP Address range(s)".
Neither NAT.
In IPv6 ALL and EVERY IP address is (or at list, is intended to be) public/ routable. No portion of IPv6 address space is reserved as "private range", so there isn't an equivalent of 10.0.0.0/8 & 172.16.0.0/12 & 192.168.0.0/16!
And here comes many people lack of understanding: there is the possibility to implement IPv4 things (like NAT, port fwd etc) to IPv6 standard, mainly but not only for security or/ and IP range isolation/ filtration purposes, but IPv6 is made to be used, preferably, only with route, without NAT etc.
Hope this helps.
This begs so many questions, but I guess my first would be, let's say that sometime in the future you have a pure IPv6 network - how do you keep all your local network devices together? Who assigns the IPv6 addresses?
Put it this way - if my local network is in the 192.168.1.x range and my ISP changes my WAN IP address, or I get a new ISP that assigns me a different IP, my local network for the most part doesn't care - it still keeps using the same local IP addresses. Let's say I had to go without any Internet access at all for a few days; the devices on my local network will still happily communicate. But if there is no such thing as a local IP address in IPv6, then who assigns the IP addresses so that there are no conflicts, and how do the ISP's know how to route traffic to any given IPv6 address? If it is the responsibility of the ISP's to assign addresses then if you get a different ISP or move, everything would change. If each networked device has an IPv6 address assigned at time of creation, then how would an ISP know how to route traffic there, given that the device might move around between networks or even be part of an isolated network? Or, if you just get to arbitrarily assign an IPv6 address, then what's to keep you from stepping on someone else's IPv6 address?
I just can't conceive of not having a local network where you can keep all of your devices grouped together. I can see why IPv6 hasn't been catching on!
