Nope.
You're going backwards in your numbers anyway...
Starting point = 172.70.32.0
172 70 32 0
10101100 01000110 00100000 00000000 = Starting point
in binary
===========================================================================
00000000 00000000 00011111 11111111 = Mask in binary
10101100 01000110 001xxxxx xxxxxxxx = Result for what
is or is not permitted.
Now start plugging some of the values into the third octet (in binary) and
make sure that the first three bits are "001" and never change.

Excuse my thick skull.
Would it be fair to say that is access-list is permitting the following
range of networks?
10.70.128.0 - 10.70.32.255
thanks
