Hello,

From all those who have taken the current CCNA exam, which type of
subnetting questions did you have? Does the exam focus on a particular class
(Class C hopefully). Were you required to hammer out all the subnets
available in a class A range? Any tips on increasing subnetting speed
(memorizing powers of 2)?


Thanks in advance.

I use the 256- (number you want to increase by).


hmm, let me explain....

you want to go up in 8's? then it's 256-8 = 248

so 255.255.255.248  will be

..0
..8
..16
..32 etc

if you're doing it to a class b it's the same.  lets try going up in 4's
instead...  so, 256-4 = 252

255.255.252.0

if was start at 172.16.0.0 then you would get

172.16.0.0
172.16.4.0
172.16.8.0
172.16.12.0

make any sense?

I use this method pretty much entirely.
