.Classful IP Range Calculation - ANSWER-If the first bit is a "0", it's a class A address (Half the address
space has a "0" for the first bit, so this is why class A takes up half the address space.)
If the second bit is a "0", it's a class B address (Half of the remaining non-class-A addresses, or one
quarter of the total.)
If the third bit is a "0", it's a class C address (Half again of what's left, or one eighth of the total.)
If the fourth bit is a "0", it's a class D address. (Half the remainder, or one sixteenth of the address
space.) If it's a "1", it's a class E address. (The other half, one sixteenth.)
