There's a number of networks from that list that have been deprecated from
filtering (e.g. they've been assigned!)...
But You should already know the RFC 1918 ones (included), then others should
be obvious:
127/8 Loopbacks
169.254/16 Microsoft
224/4 Multicast
240/4 Research
Then there's the first and last class of each class grouping:
0/8 and 127/8 (above)
128/16 and 191.255/16
192.0.0/24 and 223.255.255/24
Then there are some odd ones for testing purposes:
192.0.2/24
198.18/15
All the rest have been otherwise allocated.
So if you just understand the breakdowns there, honestly, about the only
thing to really memorize (something new anyway) are those two testing
networks.
Just my thoughts. Yes, it's irritating, but not that bad!

If we are talking RFC 3330, that is a whole bunch of numbers to memorize!
0.0.0.0/8
10.0.0.0/8
14.0.0.0/8
24.0.0.0/8
39.0.0.0/8
127.0.0.0/8
128.0.0.0/16
169.254.0.0/16
172.16.0.0/12
191.255.0.0/16
192.0.0.0/24
192.0.2.0/24
192.88.99.0/24
192.168.0.0/16
198.18.0.0/15
223.255.255.0/24
224.0.0.0/4
240.0.0.0/4
Are you sure there's is no information to be found on the doc CD about this?
In my opionion a SP CCIE should know every tiny biy of all the techniques
and protocols on the blue print but NOT memorize lists like this.
Cheers,
Koen
