Custom subnetting practice
I need to find a site/book where I can get some much-needed practice with custom subnetting. I'm only in class C right now, and the teacher is gives us either the number of hosts needed or the number of networks needed, along with the IP, and we have to find out the rest. I"ve been to "learnsubnetting.com" and it's ok, but I would actually prefer a different site or some kind of workbook. Any help would be great. Thanks.
