When I say your own I mean...
Give them a major net 135.50.0.0/16, or something like that.
Then say R2 tokenring needs to be a /28.
R3 to R5 P2P connection needs to have no more than two host addresses.
So on & so forth.
Make them work a bit to figure it out.
This was vital to my understanding of subnettting/VLSM/CIDR.
I thought I really knew all this stuff well until I hit the rack.
Then I realized after 8 months that now I can crank it out without even thinkin
g about it & how little I really did know.
Also as far as time is concerned.
I can address & get layer 2 operational on a 10 router lab in less than an hour
. frame/atm/switching/ the works.
Helps pound all the meaningless stuff that you might overlook into your head so
far that you can never forget it.
Of course this is just my opinion.

Thanks, Dan. That is something I've been concerned about myself since
the one-day format with preassigned addresses was introduced. As
should be fairly well known, I tend to be compulsive about
addressing, and would prefer to do my own.
The counterargument is that the real labs may play some specific
games with addressing to make things difficult. In other words, your
decent addressing plan would avoid some of the problems the real test
would force you to construct.
You have given me the idea that scenarios perhaps should give the
user an option whether or not to accept preconfigured addresses. The
only caveat I might make on that is that commercial labs may require
you to use specified addresses to reach resources (e.g., test
generators, TFTP servers) outside the pod.
