Quick Subnetting (Good for exams)

excellent !!!

I'm going to print it out and work through it at my leisure.

Kool, this is what I need to put things into perspective. I can now stop using my fingers and toes

Since we know /24 is 255.255.255.0, you can take a short cut, and use one lower mask. /23 is 255.255.254.0. Now we take the 256 - 254, and we have a block size of 2. The first network is 172.16.0.0 and the second one is 192.16.2.0, up to 172.16.56.0, where our host is on.

Im confused was the first network 172.16.0.0 to 172.16.2.0 so hosts would be 172.16.0.1 to 172.16.1.254 so 508 useable hosts?

was the 192.16.2.0 typo?
