Apple doesn't ever get down to tin tacks on its network gear.
But the standard Apple router configuration is to use 10.0.1.1 as home address but it still uses Class C subnet.. 255.255.255.0
The default dhcp range is 2-200 and the lease time is set to one day.
Those values are what I would stick with unless you know what you are doing.
My suggestion to help issues would be setting dhcp reservations for those things that are best kept at a static IP.. and set the lease time to 1hour to keep the renewal period short for devices using dynamic addresses.
In the old utility you could track some of this info but the new utility is near useless.
You will need other utilities to track things like DHCP and the number of devices on a network.. FING is an excellent free app for the iOS.
As a btw .. there is a bit of diagnostics on the iOS version of the utility.. it only applied to the latest gen AE and TC.. but it does contain some interesting stuff.. although most of it means nothing to me. Apple collects it.. in the background.. it never shows in the Mac version..
Click on Diagnostics and Usage.
You will see a bunch of dated files.
Some bits of some of them I can make sense of.
Some of it is goobly-gook. There are several pages worth in this one.
I got rid of my AC version TC.. so I have none of that info now.. and I do not miss it.. actually I do have serial access if I need it.
But for most of what people use you won't need this level. This is obtained by soldering in a serial port.. i do not recommend it to the faint of heart.

I can add changes to the route table.
tcgen4# route add -net 8.8.8.8/32 127.0.0.1
add net 8.8.8.8: gateway 127.0.0.1
tcgen4# route show
