Does RT-N66U support all these private network configurations?

I don't know to what extent, but I can say that it does not fully support subnets larger than a /24. Most of the firmware does, but if I remember there are a few places here and there where it's hardcoded to a /24 max.
 
Remember the RT-N66U like many other routers in its price range are intended for home use...with say an average of 8 clients.
The number of supported IP addresses (in theory 256), is related to available memory and CPU speed.
Those home usage routers will not even support 256 active clients, routing tables will run out of memory and routing the data will become dead slow.

With the increasing home demand, with fibre to the home, an increasing number of IP (IPv6) enabled devices in our home (CCTV, refrigirators, IP TV), Video On Demand on TV's in all rooms including the bathroom, also routers will become more powerfull.
Routers will basically no longer be required when (if ever) IPv4 is phased out and there is IPv6 only.

It is a bad news but thanks for letting me know this.

You might still be fine with a /16 (for example). The main location that I recall having a hardcoded /24 limitation was Networkmap - which wouldn't be critical to actual router operation.

And if you actually track down additional locations that have issues, I'm sure these could be handled by Asus as bugs, since technically the router is supposed to be able to handle those subnets.

Keep in mind however that you rarely have every single device pushing out traffic at the router's max speed. Just like no ISP in the world has the bandwidth to sustain ALL of their customers simultaneously downloading at their full capacity. So if this was, for example, an office environment, the vast majority of the traffic is going through the switch, with no router CPU or memory involved.

But on the other hand, if I needed to handle a network that had over 100+ devices, I would definitely go with a business class product myself instead of an home gateway.
 
I didn't really intend on using more than 255 computers. I just wanted to setup several groups of virtual machines and give each a separate distinctive IP range.
