There is an IBM redbooks publication called "TCP/IP Tutorial and Technical Overview", in which you can find a very clear explanation on subnetting with examples, and many other TCP/IP concepts.

You can read it on-line here, or you can download it in pdf format here.

One of the best publications I have found is the Cisco BCSN book I struggled with subnetting until I found this and it really helped me.

Here is an on-line subnet calculator the page also has some other really handy network tools as well. It is from my "Handy Hacks" Favorites Folder.
