Troy & list,
I think the reference to "summarize...as much as possible" is open to
interpretation, but my understanding of that statement would mean to reduce
the number of networks covered by the supernet to the smallest number
possible number while covering the indicated networks.
When you convert to binary, note how the first four digits are identical.
100 = 01100100
110 = 01101110
96 = 01100000
So, I would use 192.168.96.0 255.255.240.0 (/20 length) to summarize the
above.
Enjoy,
Ken W
