A good explanation is on page 306 of Caslow's book. He has six examples
to work with.
He suggests color coding your common bit values;
10000010.00001010.00101010.000 which is 130.10.32.0 255.255.224.0
You get a lot of waste in your example in the summarization as the
addresses are so far apart.
Summarization is classless..
