Minor nitpick, 10.2.0.0/8 is not a valid subnet mask. The largest subnet you can make starting with 10.2.0.0 is 10.2.0.0/15. As far as I can tell everything was done in 10.0.0.0/8 but Amazon has took down EC2-Classic documentation.

I believe it is valid, the /8 masks it so the 2 might as well be a 0.
