This might help http://www.gtoal.com/subnet.html
Also, I recomment any Cisco prep books by Todd Lammle. He has a method that will have you subnetting in your head after the chapter. He explains the binary (M$) way and then defines some rules to remember that are always true because the nature of the binary. Then you use those rules to determine the hature of the subnet without actually doing the binary conversion. I am sure there are similar methods, I just learned his first and loved it.

Doh...I forgot about the network address. "Always subtract 2" I have that drilled in my brain, don't know how I forgot it.
Ahhh, I see, you're saying "host number" is out of the available hosts which one this is.

My dept went to a really excellent Cisco course last year and one of the things the instructor taught us was how to calculate subnets in our heads after just 30-minutes of going over it with us. (really great instructor, btw...)
It kinda freaks out the geeks in the other departments when we do it for them because we haven't told them our secret. They just kind of give us that "Rainman" look.

I also have one with "SELECT * FROM USERS WHERE CLUE > 0"
And one in binary that converts to "You are dumb"
Ok, I am a geek. oh yeah... I have one that says

Not the kind of geek you were hoping for: computer. I'm a math geek, though. We're our own special, elitist breed.
